About MP4
MPEG-4 Part 14
An ISO container standard (ISO/IEC 14496-14) based on Apple's QuickTime format. It usually holds H.264 or H.265 video with AAC audio. Use it when a video has to play on any phone, browser, TV or editing app.
About OGG
Ogg Vorbis
Ogg is an open container from the Xiph.Org Foundation, and .ogg files usually hold Vorbis, a royalty-free lossy audio codec. Use it for games and open-source software that prefer a patent-free lossy format.
