# Video Edit

Cut, join and shrink video without leaving your own machine

## What this does

You have raw footage and need it shorter, joined up, or small enough to post. This handles the common video chores on your own computer: cut a section out, stick clips together, change the size, take the sound out, or turn one format into another. Reach for it when you want the edit done without uploading anything.

### Top 3 things it does for you

- Trim a clip down to the part you want
- Join several clips into one
- Resize a video for where you are posting it

A scan is named by the exact content it read, not by a version number. A different version is a different artifact, and nothing here applies to a version AIR has not scanned.

## About Video Edit

Everyday video work, done locally with ffmpeg. Trim and cut segments, concatenate clips, resize, change speed, add an overlay, extract audio, compress, and convert between formats.

Useful when you need a clip shortened, several clips joined, a version sized for a social platform, the audio pulled out or replaced, a smaller file, a different format, or just the basic information about a video file.

## Questions

### Is Video Edit safe to install?

AIR scanned this exact version of Video Edit and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit fdd6457fed4d, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/video-edit.

### How do I install Video Edit?

Open https://airmarket.ai/app/video-edit on Air Market and use the install action: Air Market hands Claude a prompt naming this exact skill, and Claude sets it up. Source, pinned to the exact commit this listing describes: https://github.com/calesthio/OpenMontage/tree/fdd6457fed4d00aef47e40cc0a7635e6d37d5729/.agents/skills/video-edit. Install from that link, not the branch.
