Video Trimmer

Pick a start and end time and save just that slice of a video as a WebM.

Start time (seconds)

End time (seconds, blank = to end)

How it works

Times are in seconds; use decimals for sub-second precision.
The slice is re-encoded as WebM with the browser's MediaRecorder.
Leave the end time blank to keep everything from the start time to the end.
