Thank you very much for the response :). Unfortunately I'm not a 
programmer but an animator, i simply love to dive into technical side of 
the story, but stated before clearly not to learn any programming. It 
would be simply too much :) for my head. Learning perspective, 
proportions, color/value relations from the artistic point of view is 
enough for me for next 5 years i assume :). I'd love to stick with HDTV 
resolutions and mp4 container (along with h.264 and aac) for storing my 
work, hence the question :). Hope you'll find some time to get the 
feature to work :).

I guess then it won't be possible in the near future to store full YUV 
information in mp4 via x264.

Thank you for the response!
Keep up great work for the community I'm really impressed as an average 
user!
