About AVI
Audio Video Interleave
Microsoft's RIFF-based video container from 1992. It is mostly found in older camera footage and DivX or Xvid files. Convert AVI to MP4 to play old clips on phones and current players, usually at a smaller size.
About M4A
MPEG-4 Audio
An audio-only MPEG-4 file, the format iTunes and Apple Music use. It usually holds lossy AAC and sometimes lossless ALAC. Use it for iPhones, Macs and iTunes libraries, where it plays and tags natively.
