Non-Destructive Trimming: Preserve Your Original Video

Trimming lets you shorten a clip by adjusting where it starts and ends. Bitcut uses non-destructive trimming — the original video file is never modified. You're simply choosing which portion of the source video to show on the timeline. You can always extend a clip back to its full length.

How to Trim a Clip

1

Select the clip

Tap the clip on the timeline. A blue border appears and the clip toolbar shows at the top.

2

Drag the left edge

Grab the left handle of the selected clip and drag it to the right. This moves the start point — the beginning of the clip is trimmed away. The preview updates in real-time so you can see exactly where the clip will start.

3

Drag the right edge

Grab the right handle and drag it to the left to trim the end point. Everything after this point is hidden from playback.

4

Release to confirm

When you release the handle, the trim is applied. The timeline adjusts and subsequent clips shift to fill any gap.

Zoom In for Precision

Pinch to zoom into the timeline before trimming. At higher zoom levels, each pixel represents a smaller time increment, giving you frame-level control over where the trim lands. This is especially useful when trimming speech clips to start exactly on a word.

Extend it back: Made a mistake? Just drag the edge back in the opposite direction to restore the trimmed portion. Nothing is permanently removed.

Trimming Clips with Subtitles

If a clip has subtitles, trimming adjusts which words are visible. Words outside the trimmed range are hidden automatically. The subtitle timing stays synced — no manual adjustment needed.
