A bit of a warning about using FFmpeg if you dont want col= orshifs.=C2=A0

I have found if i use any intermediate codec in YUV colo= rspace that the colors will shift slightly when read by FFmpeg. Doing an RG= B encoded intermediate file i dont see any noticeable colorshift. But that = normally means uncompressed, and very large files, for FFmpeg to be able to= read it.

But i too have noticed the mushed out details in the Ma= inConcept encoder in AME that the article talks about. Hopefully Adobe is p= ressing MainConcept to do something about it in the encoder since i would b= elieve they are a big customer of theirs... :-)

I should check out that x264pro plugin soon, the best o= f both worlds: Adobe handling the reading of the file and showing correct c= olors, and x264 encode for best quality... and all within AME :-)

Hmmm, I believe it.=C2=A0 There is room for vast differences in encod= er software quality.=C2=A0 I assume the Adobe one was written in-house.

x264, part of FFmpeg, is generally recognized as the best H.264 encoder.=C2= =A0 You could output your video from Premiere to an intermediate format an = then play with settings in FFmpeg.=C2=A0 You'll have to learn a little = command-line mojo, you'll have access to every possible setting.=C2=A0 = Or if you want a GUI, you can use VLC and others.

If you want to do it all within Premiere/AME, there's this: http://www.x264pro.com/
