API

video-compress

Runs in your own browser through FFmpeg compiled to WebAssembly. The default mode picks a bitrate for you; the codec can be chosen explicitly. Note that a long video takes real minutes on the caller's own CPU — budget the wait, not the price.

History

• v1 — 2026-08-02 — Initial release (browser lane).

This contract cannot change without a new version and a line above: a test compares the published schema, pricing and limits against a committed lockfile and fails the build otherwise. Subscribe to /v1/changelog to be told when something moves.
