Cut Video

Removing the first thirty seconds of dead air from a two-hour recording shouldn't take anywhere near as long as the recording itself, and it doesn't have to, since a cut made at the file's existing keyframes copies the kept footage directly rather than decoding and rebuilding the whole thing, so export time stays roughly the same whether the final clip is five minutes or ninety, rather than scaling with how much footage gets kept. This tool cuts and trims video files by copying footage directly from existing keyframes instead of re-encoding, keeping export time fast and largely independent of the result's length. Useful for trimming a long recording down to a short highlight without an export that scales with the original length, removing dead air from a stream recording in seconds, or cutting a large file down to its relevant section quickly regardless of how much ends up being kept.
