using qt-faststart
extract qt-faststart.exe
cd “directory that contains qt-faststart.exe”
qt-faststart “input.mp4” “output.mp4”
using mp4box
extract it somewhere
cd “to mp4box dir”
extracting video
MP4box “filename.mp4orwhatever” -raw 1
then
extracting audio
MP4box “filename.mp4orwhatever” -raw 2
muxing them together
MP4box -add video_file_u_just_extracted.h264#video -add audio_file_u_just_extracted.aac#audio -fps somevalue “outputfile_llolol.mp4”

It’s a YouTube bug that occurs when recompressing certain h264 encodes to flv. I’m not sure why it happens, but it does. If you change the content it fixes it (for example, with my french community fragmovie it did that with the 30fps version, but not the 60fps one).
