What's Happening With a Full Frame Video That Has Lots of Black Around It When Used With The Foundation Flex Video Stack?

Take a looks at this screen shot. In QuickTime and when uploaded to YouTube these videos runs at full frame. Once I bring it into a Foundation 2 column Flex Video stack it sits upper left and is surrounded on the right and bottom with lots of black. Any idea what may be happening?

This is how they are on YouTube… https://www.youtube.com/watch?v=Xe3juSKhayc

Yeah. Just noticed as well Joe. I’ll have to make the adjustment somehow in YouTube since the raw video file in QT displays just fine.
