Cut a video
Mark the pieces you want on the timeline. Everything else goes.

Choose the pieces to keep
Marking instead of typing
Move the video to where a piece should start, press add, then drag the handles until it looks right. Preview the piece to check it. Add as many as you like, and choose at the end whether you want them joined into one video or handed back as separate files in a zip.
Why it finishes immediately
By default nothing is re-encoded. The pieces you asked for are copied out of the original stream byte for byte, which takes about as long as your disk needs to read them, and the quality is exactly the quality you started with. The catch is that a copy can only begin on a keyframe, so a cut may land up to a second or two from where you put it.
If a cut has to be exactly on the frame, switch the method to exact. That re-encodes, which takes real time and costs a little quality, and is worth it only when the precise frame matters.
Very large recordings are fine
A three-hour stream recording is not loaded into memory here. The file is mounted straight from your disk and read only where the cuts are, so the tab's memory holds the pieces you are keeping rather than the whole recording. Cutting a thirty second clip out of a multi-gigabyte VOD takes a fraction of a second and uses about as much memory as the clip itself.
That is the part hosted clip sites cannot do at any price: the reason they are slow is that the file has to reach them first. A four-gigabyte upload takes as long as it takes, whereas your disk is already right here.
Common questions
My cut is slightly off from where I put it.
That is the keyframe snap. Copying without re-encoding can only start where the video already has a full frame, which is typically every one to two seconds. Switch the method to exact if the frame matters, and accept a re-encode.
How big a file can it handle?
Much bigger than the other tools here, because the video is read off your disk rather than copied into the tab. Multi-gigabyte stream recordings work. What has to fit in memory is the output, not the input.
Can I get each piece as its own file?
Yes, choose separate files and you get a zip with one file per piece, numbered in order.
Does joining the pieces re-encode them?
No. The pieces are concatenated as they are, so a join is as fast as the cuts were. All the pieces come from one source, so they always share a format.
Is my video uploaded?
No, and for a file this size that is the whole point. It never leaves the machine, so there is no upload to wait for.
