MP4 (MPEG-4 Part 14) is a video container format based on QuickTime MOV. But unlike MOV, it adds support for other MPEG features. MP4 supports video (MPEG-4 Part 2 and MPEG-4 Part 10/H.264), audio (MP3, AAC, SLS, TTSI, and ALAC), and subtitles (MPEG-4 timed text). It’s this codec combination that gives MP4 its flexibility.

Although not a format itself, Facebook has some technical requirements regarding the type of audio/video format it supports. While most file formats are supported, it’s best to use either MP4 or MOV. Also, the video compression codec should be in H.264 with AAC sound compression at 128kbps+. You can convert any video file type to Facebook using programs such as Wondershare UniConverter, VLC Media Player, Aiseesoft Video Converter Ultimate, and more.
