Cut the useful moment. Keep the original private.

Set the interval on the picture, choose speed or precision, then verify the changed clip before download.

Speed and precision solve different cuts.

A correct choice starts with what the boundary means.

Preview

Find the content boundary on decoded browser playback before processing bytes.

Copy

Keep the original streams and remux quickly when a nearby keyframe is acceptable.

Re-encode

Decode from the requested point and encode new frames when the visual boundary must be exact.

Verify

Reopen the output and compare observed duration with out minus in.

A filename is not proof of a cut.

Cutroom exposes the command path, output bytes, observed playback duration, and tolerance. Raw footage is never persisted; only settings and the last verification receipt survive reload.
