3. Trim the start or end: move the mouse to the edge of the clip until the cursor changes, then drag inwards.
4. Remove a part in the middle: press C for the razor tool and click at the start and end of the part. Press V to go back to the selection tool, click the piece and press ⇧Delete (Ripple Delete) so the gap closes.
5. Click Export.

Trim precisely

• Zoom the timeline with the + and − buttons (or = and −) to work frame by frame.

• Want only one section? Press I and O to set In and Out points, then choose Range ▸ Sequence In/Out when you export.

Questions

Will trimming reduce the quality?

The export is re-encoded. Choose Match Source – High bitrate to keep it as close to the original as possible.

Is there a file size limit?

No server limit — files open from your own computer, so the only limit is your device.

Can I trim a video on my phone?

Yes. Drag the clip edges with your finger, and long-press for the clip menu.
