# Edit a talking video with AI and cut the filler

Updated 2026-11-09

To edit a video automatically, read the transcript and mark the filler lines and repeated takes, then cut them out. AI Video Editor also cuts long pauses. It uses rules, not an AI model, and everything runs on your device with nothing uploaded. You get an edited MP4 and a list of every cut.

## Edit a video in three steps

Use a video of someone talking, such as a screen recording, a lesson or a team update.

1. Drop the video. Choose whether to cut long pauses, filler lines, or both.
2. Finding filler needs a transcript, which Whisper makes in your browser. Nothing leaves your device.
3. Press Edit video, watch the result and read the cut list.

## How pause cutting works

Any silence of 0.7 seconds or more is cut. The tool leaves 0.2 seconds on each side of the gap, so the first and last word of a sentence do not clip. The pace tightens but the speech still sounds natural.

## What a filler cut removes

The code works on whole transcript lines, because the timing is known for each line and not for each word. A line made only of filler words, or one the speaker restarts soon after, can go. A short um inside a good sentence usually stays. The filler rules are English, and the restart rules work in any language.

For cuts at word level you still need a manual editor.

## Reading the cut list

The list gives the time and the reason for every cut, measured on your original video. Your original file is never changed. If a cut was wrong, find the time in the list and restore that section in your own editor, since there is no screen for reviewing cuts first.

## Size limits

Every frame is encoded again, so the limit is 120 MB, or half of that on a phone. The output is an H.264 and AAC MP4 at the original picture size.

## Questions

### What leaves my device?

Nothing. The transcript is made in your browser and a word list finds the filler, so no audio, text or video is uploaded.

### Is there a limit?

Yes. Each press of Edit video uses one of the 5 free AI runs shared across tools in any rolling 24 hours, even if you only cut pauses.

### Does the edit change the picture quality?

The video is re-encoded to H.264 at its original size, so expect a normal re-encode and keep your source file.
