H.264

H.264, also called AVC, is a video coding format used in many media workflows.

Updated 2026-10-29 · Topicut editorial

Meaning

H.264, also called AVC, is a video coding format used in many media workflows.

A practical example

A delivery specification may request H.264 video inside an MP4 container with a separately defined audio codec.

What to check

A codec name alone is incomplete. Resolution, profile, level, pixel format and decoder support can affect whether a particular export works as intended.

For a related planning or text task, open the youtube chapter formatter. The tool has its own limits; its result is not a measurement or approval of every concept described here.

Continue with the video glossary or a workflow guide.
