- H.264: plays everywhere, YouTube's favorite. Larger files, universal compatibility.
- H.265 (HEVC): half the file size, same quality. Slower to encode, not supported on old devices.
- ProRes: editing codec, huge files, best quality. Mac workflows love it.
- VP9/AV1: YouTube and streaming codecs. Great compression, slow encodes on weak machines.
A phone that records H.265 will choke a five-year-old laptop. Check your editor exports what your delivery platform wants, at the resolution you shot.

Format friction should never cost money.
