I've created a comp in AE that renders very well .mov with Animation codec.

If I export it using h.264 coded in .mp4 (both from AE or Encoder), black pixels (default background) looks brown! This happens watching the video with QuickTime 7 and VLC 2. I have other players (such as WMP) that playbacks without any color problems.

I've tried to change color profiles in AE but honestly the video looks good in AE itself.

Have you ever encountered this problem?

What could I try?

That's a well-known issue with h.264 gamma shift in the Quicktime player. You've verified that the video is correct in AE and windows media player so the video is fine. If you have dual monitors, you can position the QT player so it's partially in both monitors and sometimes the gamma shift goes away. It's weird. Anyway, it's just a quicktime problem. You can check google for more info, there's plenty out there.

Yes, before posting I searched on google and I found that problem.

However I have the same problem on VLC so I was thinking about a different cause!

Thank you
