# Video Transformations

> Resize, trim, extract thumbnails, and re-encode videos with URL-based parameters

<Warning>
  Video processing is resource-intensive (5–30s per file). For high-traffic assets, [prewarm](/media-transformations/upload-and-prewarm) transformed variants at upload time so the first request is served from cache.
</Warning>

All video transformation parameters, the CRF quality table, and examples are documented in the API reference.
