Trim or Cut a Video

Remove the bits you don't want, or keep only the part you need. You can save without re-encoding, so the picture stays exactly as it was, and the video never leaves your device.

How to Trim a Video

Open your video in the video editor.
Drag across the timeline to select a part. Press + to zoom in for a precise selection, and drag the selection's edges to adjust it.
Press Delete above the timeline to cut the selected part out, or Trim to keep only that part (the Cut tool on the left has the same two buttons: Delete selection and Keep only the selection). Repeat as often as you like; Ctrl+Z or the undo arrow above the timeline takes back any step.
In the Compress tool on the left, set Save as to Lossless (cuts only) for a fast save in the original quality, or Maximum quality for cuts on the exact frame.
Press Save MP4 at the top right. A WebM video saved Lossless stays WebM, so the button says Save WebM.

Questions

What's the difference between Lossless and Maximum quality?

Lossless copies the original video data, so it's fast and changes nothing, but cuts can only fall on the video's keyframes; the editor shows how much extra it will keep. Maximum quality encodes the video again, so every cut lands on the exact frame you chose.

Why is Lossless greyed out?

Lossless only cuts. Once you add a logo, music, fades, an ending, text, a filter, transitions or more clips, rotate or crop the picture, or change the speed or the volume, the picture or sound has to be encoded again; the editor says what blocks it. Subtitles don't block it, but they aren't burned in: save them as an .srt file instead.

Do subtitles still match after I cut?

Yes. Subtitles move with every cut, and the ones in a removed part go with it.

How long can my video be?

Up to 2 hours on a computer, and up to 30 minutes and 1 GB on a phone. Videos over 10 minutes open with a note that saving may need a lot of memory.
