# To optimize OGV videos
Run `npx optimo video.ogv`. Optimo applies format-specific FFmpeg-powered compression that typically reduces OGV file size by 15–40% without visible quality loss. The original file is kept if the output is not smaller.

## Command
Start here. Run optimo on a video file:

```
npx optimo video.ogv
```
Tip: add `--dry-run` to preview changes.

## When to use OGV
- niche workflows
- open codec experiments

### Trade-offs
- Limited modern usage
- Compatibility varies

## Related formats
- [MP4](/content/optimize/mp4/index.html): The most compatible web video container; a safe default for delivery.
- [WebM](/content/optimize/webm/index.html): Web-first video format that often compresses well and is common for modern browsers.
- [MOV](/content/optimize/mov/index.html): Common container from cameras and editing tools; typically converted for the web.
- [MKV](/content/optimize/mkv/index.html): Flexible container used in many workflows; commonly remuxed/converted for delivery.
- [AVI](/content/optimize/avi/index.html): Legacy container format; usually worth converting to MP4/WebM.

## Frequently asked questions
### How do I optimize OGV files?
Run "npx optimo video.ogv" in your terminal. Optimo applies format-specific FFmpeg-powered compression that reduces OGV file size while preserving quality. The original file is kept if the optimized output is not smaller.

### Is OGV optimization lossless?
By default, optimo uses lossless optimization for OGV. For additional compression, add the --lossy flag to allow minor quality trade-offs for significantly smaller files.

### What tools does optimo use for OGV?
Optimo uses FFmpeg under the hood with format-specific settings tuned for OGV files.
