YouTube says that it accepts the MPEG2 format, and so I uploaded an MPEG2 video file of my movie and indeed it looked great, much better than MPEG4 or H264. However, there was no audio, as the mp2 video file is independent of the audio file. I then found no way to swap the audio in.
Does anyone have a solution to this? Can I upload the audio file by itself and then combine the two?
Had to make sure the m2v and aiff files have the exact same name, then opened the MPEG Streamclip app and just opened the m2v file...it brings in the aiff file with it automatically. Then chose File/Convert to MPEG with MP2 audio
