Split a long video into parts

Cuts a clip into fixed-length pieces — for a series of shorts, or when an upload limit forces you to break a recording up. Nothing is re-encoded, so even a long file finishes quickly at the original quality.

FAQ

Before you start

01
Will each part be exactly 60 seconds?
Cuts land on keyframes, so parts come out near the length you asked for. Hitting it exactly means re-encoding, which would take minutes per 20-minute file in a browser. Quality and speed won that trade.
02
Does splitting cost quality?
No. The streams are copied as they are, so every part matches the source.
03
Can I get all the parts at once?
"Download all" saves them one after another. Browsers block a burst of simultaneous downloads, so they are handled in sequence.
04
Can it split at scene changes automatically?
Yes. Pick "at scene changes" and press "find scenes": it looks for the points where the picture changes sharply and cuts there. It has to read through the whole clip, so it takes a while; adjust the sensitivity if you get too many or too few. Changes closer together than two seconds are merged.
