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 WAV
Waveform Audio File Format
A RIFF-based audio format from Microsoft and IBM, released in 1991, that almost always holds uncompressed PCM. CD-quality stereo takes about 10 MB per minute. Use it for editing, mastering and tools that want uncompressed audio; convert away from it to save space.
