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

Thanks Dave. I'm finishing up some other work tonight, so I'll be trying
these suggestions tomorrow and I'll let you guys know how it plays out.

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.

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!
