I am working with a video vendor who just ripped a dvd and sent me BOTH m4v files AND aac files (audio and video separately),. When I asked him why he did not just send 1 m4v file with the audio and video in ONE FILE, he wrote me back this (Which I need to confirm is true or false):
.M4V is a video format that doesnt directly support audio so the computer automatically rendered the audio files out as .AAC. What you say is an .MP4 format is really just the "file type" and not the extension itself.
Doesn't sound quite right, but I am not a video pro. But I do not want to have to splice all these files together again.
Please advise: Is his statement (above) correct?
