Google cares about page speed and mobile responsiveness. Those are big now. As mentioned, you should make sure you have the alt text supplied if these are images. If they’re just text, then Google will see it.
Long story short, I’m not sure if worry about it if you’ve done your diligence in the other areas.
This is a curious one because I have come up against this myself and it led me to disable the animations for a while. I am using Animate from Foundation that appears to be identical to Animagic with all the same options.
A few days ago I changed another site from an RW theme to Foundation and ran the same test in Webmaster tools but to my surprise found that it captured the entire page without problems.
In terms of SEO animations didn’t seem to affect my rankings one way or another but I am selling via the site and the animations lead to improved sales on average, so from that perspective alone it seems like the animations are worth keeping.
The one thing I have found that doesn’t render now when Google renders the page are Vimeo videos and they are also slowing down page opening so I need to find another solution for that.
