✳ GLOSSARY
What is mp4?
The most widely compatible video container, accepted by every social platform, phone and editor.
An .mp4 file almost always holds H.264 (or increasingly HEVC) video with AAC audio. That combination has hardware decoding built into practically every device made in the last fifteen years, which is why MP4 plays everywhere without taxing the CPU.
MP4 with H.264 video and AAC audio is a common delivery choice. The container alone is not a guarantee: check the destination codec, duration and file-size requirements.
Koldflux picks the right codec, container and bitrate for every platform automatically - this glossary exists because our own team had to get it right first.
