# AI Video Editor

ToolSugar AI Video Editor tidies a talking video in two ways, both in your browser with no upload. Pause cutting finds silences. The filler option transcribes the speech, then fixed rules mark filler lines and restarted takes. No AI model decides. You get an edited MP4 and a list of every cut with its reason.

Runs on your device

## How it works

1. Drop a talking video. Choose whether to cut long pauses, cut filler lines and retakes, or both.
2. With filler cutting on, set the spoken language for the transcript. Nothing leaves your device either way.
3. Press Edit video, watch the result, and read the cut list to see what was removed.

## Key facts

- **Pauses**: Silences of 0.7 seconds or more are cut, leaving 0.2 seconds on each side so words do not clip
- **Filler cuts**: Whole transcript lines, because speech timing is known per line and not per word
- **File size limit**: 120 MB, or half of that on a phone, because every frame is encoded again
- **Free runs**: Each edit that cuts filler words counts as one of 5 free AI runs in any rolling 24 hours, with no sign up
- **Output**: An H.264 and AAC MP4 at the original picture size, plus a cut list

## Common uses

- Cleaning up a screen recording where you paused to think between steps.
- Tightening a talking-head update before sending it to a team.
- Removing false starts from a course lesson recorded in one long take.

## Questions

### Will it remove every um and uh?

No. A cut covers a whole transcript line, so a short um in the middle of a good sentence often stays, because removing it would take the sentence too. Lines that are only filler go, and the filler rules are English. For word-level precision, you still need a manual editor.

### Can I skip the speech step?

Yes. Turn the filler switch off and only long pauses are cut. No speech is transcribed, so the speech model is not downloaded and the job is faster. Nothing leaves your device in either mode, and each edit still counts as one of the 5 free runs.

### What if it cuts something I wanted to keep?

Your original file is untouched. The cut list gives the time and reason for each cut, measured on the original video, so you can restore a section in your own editor. There is no screen for reviewing cuts before the video is made.
