# Edit video (https://openclip.app/docs/tools/edit-video/)



Edit video is six small operations under one roof. Pick an operation, set its options, and get an MP4 back. Every operation in this family outputs MP4.

Open it at [https://openclip.app/tools/edit-video](https://openclip.app/tools/edit-video), or press Cmd-K and type the operation you want ("trim", "crop", "mute").

## Trim [#trim]

Cut a video down to a time range.

| Option     | Type                  |
| ---------- | --------------------- |
| Start (ms) | Number, defaults to 0 |
| End (ms)   | Number                |

Times are in milliseconds. Leave End empty to keep everything after the start point.

## Crop [#crop]

Reframe the video. Two ways to define the crop:

* **Aspect ratio**: pick a preset and the tool centers the crop for you.
* **Pixel box**: drag a box in the visual crop editor, which sets exact X, Y, width, and height in pixels.

| Option                      | Choices                                    | Default |
| --------------------------- | ------------------------------------------ | ------- |
| Aspect ratio                | 1:1, 9:16, 16:9, 4:5                       | 9:16    |
| X / Y / Width / Height (px) | Free-form pixel values via the crop editor | N/A     |

## Rotate [#rotate]

Turn or mirror the video.

| Option  | Choices                    | Default |
| ------- | -------------------------- | ------- |
| Degrees | 90, 180, 270               | 90      |
| Flip    | None, Horizontal, Vertical | None    |

Flip sits under advanced options and can be combined with a rotation.

## Resize [#resize]

Scale to exact dimensions. Both fields are required; there is no aspect-lock, so mismatched values will stretch the video.

| Option      | Range     |
| ----------- | --------- |
| Width (px)  | 1 to 8192 |
| Height (px) | 1 to 8192 |

## Compress [#compress]

Shrink the file. The simple path is a target size; the advanced options give finer control.

| Option         | Choices                                                                         | Default  |
| -------------- | ------------------------------------------------------------------------------- | -------- |
| Target size    | Small (10 MB), Medium (25 MB), Large (50 MB), or a custom number                | N/A      |
| Video quality  | Auto, High (8 Mbps), Medium (4 Mbps), Low (2 Mbps)                              | Auto     |
| Max resolution | Original, 1080p, 720p, 480p                                                     | Original |
| Audio quality  | Auto, High (320 kbps), Good (256 kbps), Standard (192 kbps), Compact (128 kbps) | Auto     |
| Audio channels | Stereo, Mono                                                                    | N/A      |
| Remove audio   | On/off                                                                          | Off      |
| Quality (CRF)  | Higher quality (18), Balanced (23), Smaller file (28), range 18 to 32           | N/A      |

Set either a target size or a quality value, not both. When a Quality (CRF) value is set, it takes priority over the target size.

## Mute [#mute]

Strip the audio track. No options; run it and download the silent MP4.

## Watermarks and limits [#watermarks-and-limits]

All edit-video outputs are visual, so free-plan results carry a watermark. Runs count against your daily quota, and inputs follow your plan's size and duration caps. See [Tools overview](https://openclip.app/docs/tools/overview/).
