Audio out of sync when exporting H.264. I just discovered the following: Whenever I export a H.264 in MP4 container, the audio in the resulting file goes about 10 ms out of sync. (575 audio samples to be exact.) Green is the original clip, red is the resulting file from export. I used 25fps in export settings.

Hi, I recently got the new version of ffmpegx and I though I would rerip and try out H.264 on my Team America DVD. I used the preset and only adjusted the bitrate. When done I checked it out and after about half way through the movie and until the end the audio is slightly out of sync with the video.

I have a problem with EE4 when producing an H.264 encoded MP4 file from a DV25 coded AVI file, the audio is significantly out of sync with the video. Targeting WMV from the same source works fine. Encoding to H.264 using the open source program 'Handbrake' also works fine (their de-interlacing is arguably better as well!)

Re: H.264 Pro Recorder audio out of sync.
