Although MP4 is among the list of YouTube supported format, some users still receive "invalid file format" error message when trying to upload MP4 to YouTube. That's because MP4 is a container format that can be encoded with many different types of codecs, such as Divx, H264, MPEG-4, H.263 and audio codecs AAC, MP4, AC-3, etc while YouTube is only compatible with MPEG-4/H.264 video and AAC audio. When MP4 video that you want to upload contains YouTube unsupported codecs, YouTube will reject your video file.
