Re: [Avid-L2] H264 Problems With Exported Video

I am just talking out of my butt....but Ive had odd stuff with H264 out of Avid before. We found that the X264 codec ( free opensource) works better.We had good luck using that with QT Pro, coming from Anim QT(out of avid) For even more control, there is the MEGUI (also a free opensource project). Now the bad news...its a complicated beast with a bunch o'parts to install and master. One of my IT guys has it sorta figgered out, but I havent really had the time to play with it much, so I cant offer you any scripts, at this point.

Subject: [Avid-L2] H264 Problems With Exported Video

Hello,

I'm exporting a 720p video to H264 from Xpress Pro HD 5.2.7. The video's
high contrast black & white, blown out whites. The white wall in several
shots throughout the exported video flashes between white and grey.

I've never had trouble exporting anything to H264, I have the correct
QuickTime and nothing has changed on my system. I exported other videos to
H264 after this problem and they're fine. I've tried exporting this video
with several combinations of H264 settings and I always get exactly the same
result.

I tried exporting the video to DNHD and the problem does not exist there,
however, there is a different flashing where the edges of the blown out
whites meet other darker objects in the frame. I brought the whites way down
to see if it would resolve the issue, but it did not. I've included a link
to a short excerpt from the H264 and the DNHD exports. I hope someone can
help. Thanks!
