Claude Built This in < Hour (part 1)

In the interest of helping people understand what is possible, I present an example of using chat-based AI with Elements (not the API version, but the MCP version).

First, here’s the site: https://bythompress.com. The buttons are not yet hooked up, and this is just a preview I’m revealing to help you understand what the AI did.

Now for the main course: the following is the full chat session that created it.

byThom ZConnect — Landing Page Build Session

A chat session with Claude, working in RapidWeaver Elements — September 16–18, 2026


User

In Elements: Create a single landing page for a new app that I’m launching, called byThom ZConnect. This iOS application connects Nikon Z System cameras to your mobile device, allowing for simple, convenient, and quick downloading of images, which then can be sent on via the app to Photos, Files, Messages, and Mail.


Claude

Happy to build this in Elements — a landing page for ZConnect sounds like a fun one. Before I start adding pages and components, a few quick questions so I get the structure and look right on the first pass:

  1. Where should I build this? — New page in my open project / Brand-new Elements project
  2. What’s the launch status / main call-to-action? — Live, App Store link / Pre-launch, email signup / Coming soon, no CTA yet
  3. Visual direction? — Dark, photography-forward / Light & minimal (Apple-style) / Match my existing site design

Where should I build this? — Brand-new Elements project What’s the launch status / main call-to-action? — Live — App Store link Visual direction? — Dark, photography-forward


Claude

[Creates a new Elements project; surveys Smart Templates; sets site title and dark-mode settings; builds the page from six templates with custom copy; applies always-dark styling in two passes; verifies the render; records everything in project memory.]

Your ZConnect landing page is built in a new Elements project. Here’s what’s on the page, top to bottom: a dark hero with the byThom ZConnect wordmark, an amber “Get the app” nav button, the headline “Your Z System images. On your phone. Fast.”, and a primary App Store button; a four-step “How it works” strip (Connect → Browse → Download → Send on); a six-item feature grid (Simple, Quick, To Photos, To Files, Messages and Mail, Made for Nikon Z); a compatibility section with a checklist; an amber closing CTA (“Stop emailing yourself photos. Get ZConnect.”); and a minimal footer with the Nikon trademark disclaimer.

For the dark, photography-forward look, I didn’t rely on the visitor’s system appearance — every section background is forced to near-black (#0a0a0a) in both light and dark modes, with white/gray text and a single Nikon-ish amber (#fabc00) reserved for the eyebrow label and primary buttons. The copy is written plain and direct, photographer-to-photographer, no marketing fluff.

A few things I deliberately left for you, since I didn’t want to invent facts or links:

  • App Store URL — paste your real link into the four download buttons (hero, compatibility, CTA, and the navbar “Get the app”). I didn’t want to fabricate one.
  • Images — the hero and compatibility sections still show template placeholder photos; swap in app screenshots or a camera-plus-iPhone shot.
  • Compatibility claims — I kept them generic (“Full-frame Nikon Z bodies,” “iPhone and iPad”); tighten those to your actual supported bodies and iOS version.
  • Icons — the step and feature icons are template defaults with blue fills; you may want amber replacements.

All of this is logged in the project’s backlog and journal in Elements, so a future session will pick up right where this left off. Want me to tackle any of those next — for example, if you give me the App Store link I can wire up all four buttons?


User

I’ve made some edits of text. We now need to add a FAQ section.


Claude

[Adds the FAQ Accordion Smart Template, positions it between the compatibility section and closing CTA, writes seven Q&As, and restyles it to match the dark treatment.]

The FAQ section is in, sitting between the compatibility section and the closing amber CTA. It uses the accordion template (one question open at a time, plus-icon toggles) and matches the rest of the page: near-black section background, a slightly lighter card wrapping the accordion, white questions, gray answers, and the amber accent on the “FAQ” eyebrow. The last item carries an amber “View on the App Store” button.

The seven questions cover which cameras it works with, whether an internet connection is needed, whether images get altered, where downloads go, raw/NEF support, how it differs from Nikon’s own app, and pricing. Two of those answers I deliberately hedged because I don’t know the facts: the NEF answer points to the App Store listing for file-format details, and the pricing answer just defers to the listing. If you tell me whether ZConnect handles NEF/HEIF and what the price is, I’ll write those answers properly. Same goes for the “different from Nikon’s app” answer if you want it sharper.

I also didn’t touch any of the text you edited elsewhere on the page — and I’ve noted in the project memory that your live copy is the source of truth going forward. One small thing to eyeball in preview: the accordion’s plus/× toggle icon comes from the template and may need a color tweak against the dark cards.


User

I’ve replaced the SVGs in the Content: Horizontal Icon List section with images. Can we put a background behind those similar to what’s up at the top of the site (some sort of dark graduation).


Claude

[Reads the current page structure to find the user’s image swaps, then applies a dark vertical gradient to the four step-image holder boxes.]

Done. Each of the four step-image boxes in the “How it works” section now has a dark vertical gradient instead of the template’s solid white/slate fill: it starts at a dark gray (#262626) at the top and fades down into the same near-black (#0a0a0a) as the section behind it, in both light and dark modes. The effect is that each image sits on a subtly lifted dark plate whose bottom edge dissolves into the page — the same gallery-in-a-dark-room feel as the top of the site. The boxes keep their rounded corners and padding, so your images get a little breathing room inside the gradient.

If you’d like it more pronounced, I can start the gradient lighter (#404040), run it diagonally (top-left to bottom-right) for a lit-from-above look, or add a faint 1px gray border to define the card edges. Just say which direction to push it.

One thing I noticed while reading the page: two of your FAQ answers (“Where do downloaded images go?” and the pricing answer) refer to “byThom Ingest” rather than ZConnect — flagging it in case that’s a leftover from an earlier name rather than intentional. Happy to swap those to ZConnect if you want.


User

Good catch. I’ll fix the naming. Yes, increase the gradient and make it diagonal. Also, in the Features: Clean Grid I removed the SVG icons, but I’m not sure why the items so far apart. I like a Spacing of 2, max 8.


Claude

[Strengthens the gradient and makes it diagonal; adjusts the features grid gaps and removes leftover icon margins.]

Both changes are in.

The four step-image boxes now run diagonally (top-left to bottom-right) and start noticeably lighter — #404040 fading down to the page’s #0a0a0a — so the lit-corner effect reads more clearly against the dark section.

For the features grid, the extra distance was coming from two places. The grid’s gap was set to 10, jumping to 16 vertically on tablet and up — I’ve brought that to your preference: spacing of 2 on mobile, 8 from the md breakpoint up. But the bigger culprit was a leftover from the icons you deleted: each feature title carried a top margin of 5 that originally separated it from the icon badge above. With the icons gone, that margin was just dead air at the top of every card, so I zeroed it while keeping the small gap between each title and its paragraph. The cards should now sit as a tight, scannable grid.

Take a look in preview — if 8 still feels roomy at desktop widths I can drop the md+ gap to 6, or tighten just the vertical axis.


User

I’ve moved the SVGs to resources/svgs instead of just resources. Please note. Images will be in a resources/images folder, and svgs in resources/svgs. Also, Apple has an SVG for download on the app store that should be used where you’re using buttons.


Claude

[Finds the Apple badge the user imported into resources/svgs; checks the SVG component’s capabilities; replaces all four App Store text buttons with the badge; records the folder convention in project memory.]

All set. The four “Download on the App Store” text buttons — hero, compatibility section, the amber closing CTA, and the FAQ’s pricing item — are gone, replaced with your Apple badge SVG. The badges render at 160px wide in the three main spots and a bit smaller (128px) inside the FAQ card, and they scale up slightly on hover so they read as clickable. The black badge sits nicely on the dark sections and provides good contrast on the amber CTA card.

I’ve also recorded your resource convention in the project memory — images in resources/images/, SVGs in resources/svgs/ — so future sessions will file new resources accordingly and won’t reintroduce text buttons for download CTAs.

Two housekeeping notes from scanning your resources: meeting-bw.jpg (the old hero placeholder, now unused) ended up inside the svgs folder, and macbook-guy.jpg — still used by the compatibility section — sits at the resources root rather than in images. You may want to tidy those in the app.

The badges still need their destination: when you have the App Store URL, give it to me and I’ll set the link on all four in one pass (and the navbar’s “Get the app” button too, which I left as a small amber text button since a full badge would overwhelm the nav — happy to swap it if you’d rather have the badge there as well).


User

Apple’s SVGs needed Fill removed. “See how it works” button doesn’t scroll to that section.


Claude

[Searches Elements’ docs for the anchor mechanism; discovers the Inspector’s Advanced → ID field isn’t writable via automation after several attempts; works around it with a custom anchor component; sets Fill to none on all badges; files a field report about the gap.]

Both fixed.

On the badges: Fill is now explicitly off on all four badge SVGs, so Apple’s own black-and-white artwork renders untouched. I’ve also noted in the project memory that brand/multi-color SVGs should always have Fill disabled when placed — so this won’t recur when future sessions add SVGs.

On the scroll: the Inspector’s Advanced → ID field (Elements’ normal way to create anchor targets) turns out not to be writable through the automation interface — I tried every plausible property name and filed a field report about the gap. The workaround is clean, though: I created a one-line custom component called “Anchor: How It Works” that renders an invisible <div id="how-it-works"> with a bit of scroll-margin so the section doesn’t land flush against the viewport top, dropped it immediately above the How section, and pointed the “See how it works” button at #how-it-works (same tab). Elements ships with smooth scrolling enabled site-wide, so the button should now glide down to the section.

Give it a try in preview. If the section lands too high or too low relative to the top of the screen, tell me and I’ll adjust the anchor’s scroll offset — and if you ever add a sticky nav, that offset will need increasing to compensate.


User

Scroll to anchor doesn’t work. Meanwhile, when you hover over the first Download at App Store button you get a black graduated background replacement under the element.


Claude

[Inspects the button and badge properties to diagnose both issues.]

Found both culprits. The button’s stored link kept the control’s default “open in new window” behavior — so the click was trying to open a new tab instead of scrolling the current page. And the badge’s hover-scale is what’s triggering that dark artifact: scaling promotes the SVG to its own compositing layer, which forces the hero’s blurred background disc behind it to repaint — that’s the “black graduation” you’re seeing under the element. The clean fix is to drop the hover transform entirely.

[Applies both fixes.]

Both should behave now.

For the scroll: the link itself was fine, but Elements’ link control defaults to “open in new window,” and my explicit override apparently didn’t take on the first pass — so clicking was attempting to open #how-it-works in a new tab (which browsers often block or which just looks like nothing happened). I’ve re-set the link with new-window explicitly off, so the click stays on the page and smooth-scrolls to the anchor above the How section.

For the badge: the hover scale-up I’d added was the problem. Scaling an element promotes it onto its own GPU compositing layer, and since the hero badge sits over that blurred decorative disc in the hero background, the repaint showed up as a dark gradient patch beneath the badge. I’ve removed the hover transform (and its transition) from all four badges rather than just the hero one, since the CTA badge sits over the amber card and could have shown a similar artifact. The badges are now static; the cursor change from the link still signals they’re clickable. If you’d like some hover feedback back, a slight opacity dim on hover doesn’t trigger the same repaint problem — say the word and I’ll add it.

Test the “See how it works” button in preview once more. If it still won’t scroll there specifically (but works in an exported/published site), that would point to preview-mode hash handling rather than the page itself — worth one check in an actual browser export before we chase it further.


User

The SVG in the top bar should be replaced by the app’s icon, which is in resources/images and titled bythom-zconnect-appicon.png.

See how it works text still doesn’t scroll. No indication that it is a live button. However, don’t do anything there yet as I’m thinking about adding a video about it works. Maybe we can pop up the video when the user clicks on that.


Claude

[Swaps both the desktop and mobile navbar logos for the app icon; leaves the button untouched and logs the video-modal idea.]

The navbar now shows your app icon. I swapped it in two places: the desktop logo, where the template’s rotated-diamond placeholder sat next to the wordmark (the icon now sits there at 40px with slightly rounded corners, iOS-style), and the mobile logo, which was still showing the template’s Elements SVG. Both point at images/bythom-zconnect-appicon.png, so if you ever update the icon file, both spots update together.

And understood on “See how it works” — I’ve left it completely alone and parked it in the project backlog so we don’t lose the thread. For what it’s worth, the video popup idea is a good fit for what Elements gives us: there’s a Modal component (with a Modal Close) and a Video component, so the pattern would be the button opening an overlay with the video playing inside, on the dark page — no navigation, no scrolling involved, and it sidesteps the anchor problem entirely. It would also solve your “no indication it’s live” complaint, since opening a modal is unmistakable feedback. When you’ve decided and have the video file (drop it into a resources/videos/ folder if you want to extend your convention), tell me and I’ll wire it up — button, modal, close control, and dark styling to match. If you instead decide to stick with the scroll, the next diagnostic step would be checking whether the anchor works in an exported site versus Elements preview, which would tell us whether it’s the page or the preview environment.


User

I need to re-edit the video eventually, but zconnect.mp4 is now in the resources/video folder. Note that it is a vertical video.


Claude

[Builds the modal: dark panel, close control, and a video player sized 9:16 at 70% viewport height, loaded with zconnect.mp4 and a splash-screenshot poster. Discovers the video source property by probing, but can’t find a way to wire the button to the modal via automation.]

The video modal is built and loaded with zconnect.mp4. Since it’s a vertical video, I set the player to a 9:16 aspect ratio capped at 70% of the viewport height, so the whole phone-shaped frame fits on screen without scrolling, portrait or desktop. It sits centered in a dark rounded panel (matching your card styling) with a Modal Close control at the top, and I gave it your splash screenshot as the poster frame so it doesn’t open as a black rectangle before playback. When you re-edit the video later, just replace zconnect.mp4 in the resources — the modal picks up the new file automatically, nothing to rewire.

One step needs your hands in the app, and I want to be straight about why: connecting a button to a modal is done through the Link panel’s “Modal” target type, and that particular link type isn’t reachable through the automation interface (it only speaks URL/page/anchor/resource links — I’ve noted this in the field-report log along with the Advanced ID gap). So: select the hero’s “See how it works” button, open its Link control, and choose Link → Modal → the modal I just added. That replaces the dead #how-it-works text link currently on it, which likely also explains why the anchor never fired — the plain-text link type may not render as a real navigable href in the core button, something the modal approach makes moot.

Once you’ve wired it and confirmed the popup works, tell me and I’ll clean up the leftovers: the invisible anchor div and its custom component, which will be orphaned at that point. And if you want the button itself to look more alive, I can add a hover state (background lighten or an amber border) that won’t trigger the compositing artifact we hit on the badges.


User

I do like my buttons to hover at 103%. However, I’m not sure what you mean by “Modal” target type. I find no reference to that.


Claude

Fair challenge — I asserted that from the docs’ vague “trigger from buttons” line, and if the Link panel doesn’t show it, I was wrong about the mechanism. The good news: Realmac open-sourced the core components on GitHub, so I can read the actual Modal implementation and find out exactly how it’s triggered.

[Clones the open-source RWElementsCorePack and reads the Modal component’s source.]

Mystery solved, and I was wrong earlier — sorry for sending you hunting for a link type that doesn’t exist. Reading the Modal’s actual source code in Realmac’s open-source core pack cleared it up: a modal isn’t opened by a link at all. The modal component renders an invisible Trigger slot inline wherever the modal sits, and clicking anything placed inside that slot dispatches the open event; the dialog overlay itself is teleported to the end of the page regardless.

So I’ve wired it properly: the modal now lives in the hero’s button row, right where the old button stood, and your “See how it works” button has been moved inside the modal’s Trigger slot. Clicking it should now open the video overlay. I also cleared the dead #how-it-works link from the button and — since the button previously had a fully transparent background, part of why it didn’t read as live — raised its dark background to full opacity so it looks like a real secondary button next to the badge.

Your 103% hover is now the house standard: applied to “See how it works” and the navbar’s “Get the app,” with the transition limited to transform only, and recorded in the project’s visual style guide so it’s applied to any future buttons automatically. I deliberately left the App Store badges static, since hover scaling is exactly what produced that black gradient artifact over the hero’s blurred backdrop — if you want the badges at 103% too, I can try it with the tighter transition and we’ll see if the artifact stays away.

One leftover: the “Anchor: How It Works” custom component in your library is now orphaned (I noticed you’d already deleted its instance from the page). Want me to remove it from the component library, or keep it around in case you want scroll anchors elsewhere later?


User

Okay, the modal video works. However, now when the video starts playing we only see a horizontal swath across the middle. It’s playing as 16:9 within 9:16.


Claude

[Reads the Video component’s source and finds the inner player element hard-codes a 16:9 aspect regardless of settings; builds a scoped CSS override as a custom component.]

Fixed. The override forces the player inside the modal to honor the 9:16 frame — full width and height of its wrapper with cover fit — instead of the baked-in 16:9. It’s injected once into the page head via a “Vertical Video Fix” custom component sitting invisibly inside the modal panel, and it’s scoped to videos inside modals only, so nothing else on the page (like a future landscape video section) inherits it.

Open the modal again and the video should now fill the tall frame edge to edge. Worth knowing for the future: this is a quirk of the core Video component, not anything you did — it assumes landscape footage and hard-codes 16:9 on the actual player element, with the aspect-ratio control only shaping the outer box. I’ve logged that in the project’s concerns file, so if Realmac fixes it upstream we can remove the override, and if you ever add a landscape video in another modal, we’ll need to tighten the CSS scoping at that point.

One check when you look: with cover fit, if your edit’s frame isn’t exactly 9:16 there’ll be a slight crop at the edges. If you’d rather letterbox than crop (show every pixel with thin bars instead), say so and I’ll flip it to contain.


User

Verified working. Putting project aside for today.


Claude

Great — glad it’s all verified. I’ve logged the session in the project journal, so when you pick this back up (today, next week, whenever), the next session will know exactly where things stand.

For your own mental checklist, what’s still open: the App Store URL for the four badges and the navbar button once the listing is live, your re-edit of zconnect.mp4 (just replace the file in resources/videos/ — nothing to rewire), the compatibility section image which is still the macbook-guy.jpg placeholder, the footer social icons which aren’t linked to anything yet, and the orphaned anchor component in your library that I can delete whenever.

Nice progress for one day — the page went from empty project to a complete, dark, working landing page with a video demo. Enjoy the break, and good luck with the ZConnect launch.


User

Site has been established on my server so that I can fully test. When I click on the video in the published site I get “No video with supported format and MIME type found.”


Claude

That error message is the browser saying it either couldn’t fetch the file or couldn’t decode it — and since the modal played fine in Elements preview, the page wiring itself is sound. Two suspects, and one quick test splits them:

Open the video’s URL directly in the browser on the published site — yourdomain/resources/videos/zconnect.mp4 (adjust if your export structure differs; you can grab the exact path from the page source’s <source src=...>).

If that 404s, the file didn’t make it to the server or the path shifted — check the upload included the resources/videos folder. If it loads as a download or plays weirdly, it’s a server MIME issue: the server needs to send .mp4 as video/mp4 (on Apache, AddType video/mp4 .mp4 in .htaccess fixes it).

If the direct URL plays in Safari but the error appears in Chrome or Firefox, it’s the codec — and this is my prime suspect. iPhone recordings and many Mac exports default to HEVC (H.265), which Safari and Elements’ WebKit-based preview play happily but Firefox doesn’t at all (that exact “No video with supported format and MIME type found” wording is Firefox’s), and Chrome only sometimes. You can confirm in two seconds: open zconnect.mp4 in QuickTime, press ⌘I, and look at the format line — “HEVC” means that’s it.

The fix is re-exporting as H.264, which every browser plays. Since you’re planning to re-edit the video anyway, just export the final cut as H.264/“Most Compatible.” If you want to fix the current file immediately via ffmpeg:

ffmpeg -i zconnect.mp4 -c:v libx264 -pix_fmt yuv420p -c:a aac -movflags +faststart zconnect-h264.mp4

(+faststart also moves the metadata to the front of the file so playback starts before the whole file downloads — worth having regardless.)

Then replace the resource in Elements and republish. Tell me which branch it turned out to be — if it’s the server path rather than the codec, I’ll dig into how Elements structures resource paths on export to make sure the page and folder agree.


User

I’ve redone the video, now named /resources/videos/bythom-zconnect-intro.mp4. Can you swap that for the one that’s currently being used.


Claude

[Reconnects to the reopened project and swaps the modal’s video source to the new file.]

Swapped — the modal now plays videos/bythom-zconnect-intro.mp4. Everything else about the player (the 9:16 frame, poster image, vertical-video CSS fix, close button) carries over untouched, so it’s just the source that changed. Republish and the new file will go up with the page.

Two small notes: the old zconnect.mp4 is still sitting in your resources — now unused, so you can delete it in Elements to keep the published site lean (no rush; it just means uploading a video nobody plays). And when you test on the server, do check it in Firefox or Chrome specifically, not just Safari — if the original failure was the HEVC codec, those are the browsers that would have shown it, so they’re the proof the re-export solved it.


User

Still doesn’t work. Video is “MPEG-4 AAC, H.264” according to file data. In Firefox you get the message I noted earlier. In Safari you get just a black box for the movie, which also doesn’t play.


Claude

H.264/AAC failing in both browsers kills the codec theory — and importantly, it means both video files failed the same way, which points at something environmental: the path the page requests, the upload, or how your server serves .mp4. Let me actually look at the live site rather than theorize.

[Checks project settings for the site URL; can’t reach the unindexed test domain directly; verifies in the component source that the page emits a plain relative source path.]

The page-side code checks out — the component writes a plain relative <source src="resources/videos/…mp4">, identical in preview and publish. And here’s the telling pattern: it worked in Elements preview (served by the app itself) but fails on your server in both browsers, with both files, and both codecs. That combination almost certainly means the problem is between the browser and your server, not in the page or the video. Firefox’s exact message appears when the fetched “video” comes back as the wrong content type (like an HTML error page), and Safari’s silent black box matches the same failure.

Two minutes of testing on your machine will pinpoint it. First, view source on the published page and search for .mp4 to get the exact URL being requested (with cache-busting on it may carry a ? query — harmless, but confirm the path portion). Then check what the server actually returns for it:

curl -I https://bythompress.com/resources/videos/bythom-zconnect-intro.mp4

(adjusting to the exact path from the page source). The headers tell the whole story:

  • 404 → the file isn’t where the page thinks. Check that the resources/videos/ folder made it up in the publish/upload.
  • 200 but Content-Type: text/html → the server is intercepting the request and serving a page instead. Prime suspect on your setup: hotlink/media protection in an .htaccess — if bythompress.com inherited rewrite rules from your other sites (which I’d expect protect media files), those rules may be blocking or redirecting .mp4 requests even from your own page. A referrer-check rule that doesn’t whitelist the new domain would do exactly this.
  • 200 with Content-Type: application/octet-stream or text/plain → MIME config; add AddType video/mp4 .mp4 to .htaccess.
  • 200 with video/mp4 but no Accept-Ranges: bytes → the server isn’t honoring byte-range requests, which Safari requires for video playback (Firefox is more forgiving, so this alone wouldn’t explain Firefox — but combined issues are possible).

My money is on one of the middle two given both browsers fail identically. Tell me what the headers say and I’ll give you the exact .htaccess fix — and if it turns out to be the hotlink-protection scenario, the fix is one added condition rather than removing your protection.


User

I published the page to bythompress.com if you can look at that better. I think this is the relevnt code:

(pasted the published modal/video HTML source)

And Part 2:


User

I published the page to bythompress.com if you can look at that better. I think this is the relevnt code:

(pasted the published modal/video HTML source)


Claude

That paste is gold — I can see something suspicious in it already: the player is initialized with an empty video ID (videoPlayer('rw…', 'mp4', '', …)), and the <video> tag carries an x-bind="mp4" binding. If that binding sets a src attribute from the empty ID, it would override the perfectly correct <source> child — an empty src on a <video> element produces exactly your two symptoms. Let me check what x-bind="mp4" actually does in the component source.

[Reads the binding in the component source — it only sets muted/loop/controls, so that theory dies; then fetches the video URL directly, which fails only because the response exceeds a 30 MB fetch limit.]

Good news and bad news from the source: that binding only sets muted/loop/controls — no src — so the empty ID is normal for mp4 files and the markup is actually correct: the player genuinely requests resources/videos/bythom-zconnect-intro.mp4.

That failed fetch is actually a very useful result: the server returned a response body over 30 MB — my fetcher’s limit — which means the file exists at that URL and the server is delivering it. No 404, no hotlink block, no HTML error page (those would be tiny responses). So the upload, the path, and the page are all fine.

That leaves the file itself, and there’s one classic way a file can be “H.264” and still fail in every browser: pixel format / profile. Browsers only reliably decode 8-bit 4:2:0 H.264 (yuv420p). Editors and screen-recording workflows frequently export H.264 as 10-bit or 4:2:2 chroma — QuickTime and Finder happily play those and report simply “H.264,” so everything looks right locally, while Firefox throws precisely your “No video with supported format and MIME type found” and Safari renders a silent black box. Both browsers, file present, “correct” codec on paper — this fits every symptom.

One drag-and-drop test settles it: drag bythom-zconnect-intro.mp4 from Finder straight into a Firefox window (playing it as a local file). If Firefox shows the same error locally, the server is fully exonerated and it’s the encoding, guaranteed. (If it plays locally, then we’re down to a server header issue and I’ll walk you through capturing the Content-Type.)

Assuming it’s the encoding, re-export forcing the compatible pixel format:

ffmpeg -i bythom-zconnect-intro.mp4 -c:v libx264 -pix_fmt yuv420p -crf 23 -c:a aac -movflags +faststart bythom-zconnect-intro-web.mp4

The -pix_fmt yuv420p is the line that matters; +faststart moves the index to the front so playback starts before the full download, and CRF 23 will likely also shrink that 30+ MB file substantially — worth having on a landing page regardless. If you’re exporting from an editor instead, look for “Most Compatible,” 8-bit, or explicitly 4:2:0 in the export settings.

If you confirm which way the Firefox drag test goes, we’ll know we’ve got it — and once the new file is in resources/videos/ under the same name, republish and nothing else needs touching.


User

The Firefox drag test works fine. Video plays.


Claude

That settles it: the file and its encoding are innocent, the page is innocent — the fault is in how the server hands the file to the browser. The video plays when the browser gets the raw bytes, but through the server something about the response makes both browsers reject it. The two usual offenders are the Content-Type header (server announcing the .mp4 as something other than video/mp4 — Firefox refuses on the spot when the announced type is wrong) and, less commonly, compression (a server configured to gzip everything will also gzip the video, which corrupts streaming playback).

One command exposes both — run this in Terminal and paste me the output:

curl -sI -H "Accept-Encoding: gzip, deflate, br" https://bythompress.com/resources/videos/bythom-zconnect-intro.mp4

The lines I care about are Content-Type, Content-Encoding (shouldn’t be present at all), and Accept-Ranges (should say bytes — Safari cares about that one).

If you’d rather just try the likely fix straight away: assuming Apache on that host, drop this into the .htaccess at the site root (or add to the existing one):

AddType video/mp4 .mp4
<FilesMatch "\.mp4$">
    SetEnv no-gzip 1
</FilesMatch>

The first line is the probable cure — some hosts ship stripped-down MIME maps that simply don’t know .mp4, and everything you’re seeing follows from that. Reload the published page (hard-refresh, since the failed response may be cached) and the modal should play. If the headers turn out to already say video/mp4 with no encoding applied, paste them anyway and we’ll go one layer deeper — but I’d be surprised.

(pasted the curl headers: HTTP/2 200, content-type: video/mp4, accept-ranges: bytes, server: cloudflare, cf-cache-status: HIT, cache-control: max-age=14400, last-modified that day at 14:55…)


Claude

Those headers are textbook-perfect — video/mp4, byte ranges supported, no compression, clean 200. There is nothing wrong with how the server is configured. But two details in there tell an interesting story: server: cloudflare with cf-cache-status: HIT, cache-control: max-age=14400, and a last-modified of today at 14:55.

You’re behind Cloudflare, which caches that video for four hours at their edge — and the copy being served right now was cached at 14:55 today, presumably your latest upload. Which means: every time you’ve replaced that file during this debugging saga, Cloudflare could keep serving the previous version for up to four hours (plus your browser’s own cache on top). Your fixes may have been landing on the origin server while the browsers kept receiving the stale, broken copy — quite possibly the original problem file. It would also explain a discrepancy I noticed: when I fetched the URL earlier it was over 30 MB, but your headers show 21 MB — different versions of the file at different times.

So before anything else: test the published page right now, in a private/incognito window (or hard-refresh with Shift held). The copy currently at Cloudflare’s edge is today’s upload, the one that just passed your Firefox drag test — there’s a fair chance it simply plays.

For the rest of your testing workflow, two habits will save you this pain: after replacing any media file, purge it in the Cloudflare dashboard (Caching → Purge Cache → Custom Purge lets you purge just that one URL rather than the whole site), or flip on Development Mode (top of the Caching page) while you’re actively iterating — it bypasses Cloudflare’s cache entirely for three hours.

If it still fails in a private window after a purge, then something is genuinely odd about what the edge is serving versus what you uploaded, and the next step would be curl -o test.mp4 on that URL and playing the downloaded file — that would tell us byte-for-byte what browsers are receiving. But test first; I suspect you’ve been chasing a ghost that Cloudflare kept alive.

Yes, it appears to be the Cloudfare issue. Meanwhile, I’ve reported a couple of the issues you encountered along the way to Realmac, and they said that surfaced an issue they’ll be fixing. So you’ve been helpful to all of us.


Claude

That’s a satisfying ending — a bug hunt that went through codec theory, server config, and component internals before landing on a cache quietly serving yesterday’s mistakes. Classic. I’ve logged the resolution and the Cloudflare purge habit in the project journal, so future sessions will know to purge or use Development Mode whenever you swap media files on this site.

And that’s genuinely good to hear about Realmac — the two items worth watching are the ones we worked around: when they fix the Video component’s forced 16:9 on the inner player, the “Vertical Video Fix” override can be retired, and if they expose the Advanced → ID field to automation, anchor links become a one-step job. Both are noted in the project memory with that exact plan.

Congratulations on getting ZConnect’s page fully working end to end — from empty project to published, dark, video-equipped landing page with a real App Store presence. When the app listing goes live and you have the URL, that’s the last wire to connect. Good luck with the launch; the Z System crowd is lucky to have tools built by someone who actually shoots.

Part 3

You can see that back and forth pretty clearly in this session. I tend to have a .MD plan file that I’m working from that’s ordered the things I need, and I serve them to the AI one at a time after the initial build request. As the AI creates the frameworks, I fill in the content (e.g. FAQ section) and then serve up another request.
But this session also shows something else that sometimes happens. As it turns out, the Elements Hosting is using Cloudfare, and Cloudfare caches things like video files (for four hours). This caused a bit of grief as we tried to sleuth through why the video wasn’t working correctly. Once I loaded the new video and expired the cache, everything was fine. So sometimes you’ll go down a cul-de-sac and need to regroup.
Overall, the process of using AI to help create and style pages works very well. All this happened faster than I could have done it myself from scratch, and I’m one of the more experienced Elements users out there.
My hat’s off to @dan and the full team: this was worth the wait.

Hi @thominator

Congrats on getting the site online with the help of the MCP connection in Elements. :slightly_smiling_face:

Regarding Cloudflare, indeed it caches certain assets for 4 hours by default. You can check out the list of assets it caches here. MP4 files are on the list.

It’s best to put the site into development mode while you are working on it so that caching is paused. I’ll send you an invite to join the managed Cloudflare account so you can do that on your end. :slightly_smiling_face:

Congrats again, and thanks for signing up on Elements Hosting, we’re really happy to host you! :purple_heart:

I’m not jealous :slight_smile: So yesterday I paid $20 to a bot company to set MCP so all I asked was for it to connect to Elements and test to say it had done - simple request. I hour later all monthly credits used - please upgrade and no set up! So how many thousands of pounds did you pay for this? :slight_smile: I’m not built for AI! :slight_smile:

Congrats on the website :+1:
But honestly I would be really interested in ZConnect. When will it be available?

That doesn’t sound like MCP, that sounds like API.
If you really want to work with AI and Elements, you want to use chat outside of Elements via MCP. API use is too expensive for the token usage that gets generated.

I was targeting next week. However, you just never know with the App Store. You can submit an App and discover that you’ve violated some vague rule or didn’t fill out a form somewhere correctly, and then you get to do the process all over again. Sometimes again and again.

Thom this was not API I went into Elements MCP server and got https: code. I asked ChatGBT to set up an MCP server, it said I could not on free account but would need to have a paid account. I bought the cheapest to set it up as I dont know how much I would use. I asked it to set up the MCP now I had paid. It asked if I had the https address but not to post it yet. It hen set about creating the link via MCP server. At no time did I ask for API key nor go anywhere near menu for API key.

It would be interesting to know what a real world example like this cost to create.

Again, this was MCP, not API. Under API (directly within Elements), yeah, it probably would have been several hundred dollars. However, under MCP (chat window talking to Elements) you are paying a monthly fee, not a per token cost. I happen to have a $200/month plan, but I’m using Claude in Xcode, Excel, and Elements almost constantly, and not running up against limits or extra costs. Under the $20/month plan, you may find yourself hitting a daily limit, but it’ll be way less costly than using API.
Moreover, if you have a recent Apple Silicon Mac with enough memory, I’d suggest you just try MCP using LMStudio and Gemma4 or Gwen 3.8 (everything in that sentence except the Mac is free). Both seem to work fine, though Claude’s been at this longer and it clearly shows that it’s a little better at tech stuff as is happening under the covers of Elements.
Again, I want to point out to people that if you’re using AI within Elements, you’re using API and getting charged for every token. If you’re using a chat engine outside Elements you’re using MCP and while you have a daily ration of tokens under those plans, they aren’t counted the same way, and you should be able to get an hour or two of use every day from the lowest cost monthly plan.

I am loosing the hype a little bit… went back to two of my designs - incorporated some ideas from AI design into them…

Did a SEO pass on all pages (useful)

Starting to make a list - for me - of useful AI
Design Ideas
SEO labeling
Complex Formatting

Thom - very nice work! Nice to have the big Claude plan…

Understood, but I’m using ChatGPT (currently the free version), and virtually any use of graphics (uploading a screenshot and asking for some information), results in a very short session due to lack of tokens. It will allow continuing with text only sessions, but I expect if I was to send a screenshot of an issue with a web site for example, it would quickly become a frustration.

I’m not averse to having a paid account when needed, but I’m trying to get a real world idea of ongoing costs. I’ll look into LMStudio, Gemma4 and Gwen 3.8, though I currently have no idea what they are.

If you require free. Do as I suggest and get LMStudio running on an Apple Silicon Mac. Hook it up to Elements using MCP. Pick a model that can live in the available memory of your Mac. It’ll still be free. It might not be as good as the top paid models, but it will still be quite useful once you learn how to use it.

Short of that, invest the US$20/month to get a paid Claude account. You’ll still hit daily limits if you try to use it too much, but it’ll last a lot longer than trying to do the same thing with the free model, and it resets daily.

FWIW, I’m using the US$200/month model and basically running something all the time. I look at it this way: that’s US$2,400 a year. An entry level hire that could do not even a small portion of what Claude is doing would cost me US$60,000 a year, minimum, and would generate a great deal of paperwork in doing so. I’m getting way more value than the money I’m putting in at the moment.

Very smart with your plan choice and work flow

Have to actually try the MCP with Qwen…

Because of my long prompts and drift - Claude said it would be a nightmare and would not work - so I didn’t try it…

Smaller bite size tasks - which I am learning - should be fine…

I tried to do too much in one pass - redoing - refixing and entire site in 6 phases….

I have the elements add on templates - I wish in design it would use it more… restructure and pull in those nicely spaced sections… still working on a prompt to bring them in…

Don’t know what happened - cleaned out files - the other day and somehow deleted qwen

Got it reinstalled and MCP connected (finally)

Running Qwen SEO creation prompt on six page new site - non ai injected yet

Seems to be working!!! We shall see :slight_smile:

It is slower - but does work

Local AI model Qwen

12:12 started prompt…

12:22 reworking descriptions

Added steering task…

12:27 Trimming down to 160 characters

12:31 Presented table of titles, descriptions and og for approval

I could see starting a task then making dinner or something in the future… fan does kick in - processor peeks at about 200 degrees at times

It is workable - which is nice :+1: not to have to wait till tokens reset in 4-5 hours
