MP4 (MPEG-4 Part 14)
The most widely supported video format. Plays on virtually every device, browser, and app. Balances quality and file size well thanks to H.264/H.265 compression.
M4A (MPEG-4 Audio)
Apple's audio-only container, typically using AAC encoding. Common for iTunes purchases, Apple Music downloads, and iPhone voice memos.
