We're seeing an issue when exporting in H.264 (High Quality) and playing in QuickTime 10.0 (Mac OS 10.6). We are using a custom size video to fit a spot on our website (398x498). When exported and played in QuickTime 10.0 the white inverts throughout the video (back and forth). The same issue is not seen when viewed in VLC, QuickTime 10.1 Chrome, Firefox, Flash or IE.
We are also NOT seeing the same issue when we export the same video to a different custom size (336x596). Those videos play normal in QT10.0. And lastly we're NOT seeing this issue when exporting as QuickTime/JPEG2000 format.
Very strange. Anyone know of why this might be happening?
This is how the video should look:
And this is how they are appearing:
But like I said, the issue is very specific to QuickTime 10.0 on Mac 10.6. VLC, Flash, Chrome, FireFox all play it correctly.

How does it play in Bridge with Quicktime 10.0?
Does Bridge use QuickTime by default? Or is there an option to modify this?
The video plays fine in Bridge CS6 but shows the corruption issue in Bridge CS5.
By defalut it uses QuickTime I believe. CS6 has added video drivers so that may be why it play is CS6 but not 5.
You can change the option of what file it uses either by right clicking and choosing another program, or change the default in preferences/file type associations.
Sounds like it's just a decoding bug in QuickTime 10.0 and fixed in 10.1.
Now, how to avoid it: I'd guess that it's an overflow in their decoding of solid regions, so dropping the background to something less than pure white might avoid the problem.
