Hi, I am encoding a Quicktime Prores file to mp4 using the below settings. In the resulting file, the audio is 1 frame out of sync, audio comes in 1 frame early, cutting off the first frame and adding 1 silent frame to the end (see attached screen grab)."F:\ffmpeg copy\ffmpeg-20160115-git-b58cfa6-win32-static\ffmpeg-20160115-git-b58cfa6-win32-static\bin\ffmpeg.exe" -i small_test.mov -c:v libx264 -crf 23 -preset medium -vsync 1 -pix_fmt yuv420p -c:a aac -strict -2 -b:a 128k -y"\\10.0.1.103\Studio Canal 1_1\KEVS_TEMP\small_test.mp4" -report
And here is the output:"F:\ffmpeg copy\ffmpeg-20160115-git-b58cfa6-win32-static\ffmpeg-20160115-git-b58cfa6-win32-static\bin\ffmpeg.exe" -i small_test.mov -c:v libx264 -crf 23 -preset medium -vsync 1 -pix_fmt yuv420p -c:a aac -strict -2 -b:a 128k -y"\\10.0.1.103\Studio Canal 1_1\KEVS_TEMP\small_test.mp4" -report
