## What it does

Drop a video, scrub to the clip you want, hit I to mark the in point and O to mark the out point. The trimmed range plays inline before you download so there are no surprises.

Fast mode keyframe-snaps the in/out markers for an instant trim with no quality loss when the source codec matches the target. Frame-accurate mode re-encodes at exact frame boundaries.

## Keyboard shortcuts

I — set in point at the playhead. O — set out point. K — play / pause. J — rewind, doubling the rewind speed on each press. L — fast-forward, doubling the speed on each press.

Shortcuts work whenever the page has focus and a text input isn't selected — same convention as Premiere and DaVinci Resolve.

## How to use it

1. **Drop the video** — Drag the file in. The inline preview loads immediately.
2. **Mark in/out** — Scrub or use J/K/L. Press I where you want the clip to start, O where you want it to end. The selected range highlights on the scrubber.
3. **Trim and download** — Process renders the clip. Fast mode finishes instantly if codecs match; frame-accurate takes longer but cuts exactly at the marker.

## When to use it

### Pulling a highlight

Got a 30-minute talk recording and need the one good 2-minute segment? Mark in/out, download, share.

### Removing dead air

Top and tail a recording where the first/last few seconds are setup.

### Producing social cuts

Cut 9:16 cards from a 16:9 master without re-rendering the whole thing.

## FAQ

### Why isn't my trim instant?

Frame-accurate mode always re-encodes. Switch to Fast to use the keyframe-snap path when source and target codecs match.

### Can I trim multiple ranges at once?

Not yet — this is single-cut. To stitch multiple ranges, trim each separately and use the Merge Videos tool.

### Does it preserve audio?

Yes. Both modes carry the audio track through; Fast mode preserves the original encoding bit-for-bit.
