H264 white screen from Episode Pro
on Dec 6, 2006 at 9:41:07 pm

I have QT 7.1.3 on my Mac (10.4.8). I'm using Telestream Episode Pro to compress from a Quicktime animation compressed file to H264. When I open the file I get a white screen.

I assuming this is because I attempted the high setting with 4:2:2 selected instead of 4:2:0. Is there any resource that would explain which settings are off limits for general use? Or is there some other explanation for the white screen?

This is for viewing by specific clients rather than the whole internet.

Thanks, James

You are correct about this being an issue with QT. QT only supports the baseline and main profiles of the H.264 codec. To view High profile or 4:2:2 encodes, you need a PC and a decoder like the one available from MainConcept. VLC can semi play back high profile H.264 encodes on the mac though.
