Performance Considerations

Video transformations are significantly more resource-intensive than image operations. Keep these factors in mind:

Processing time

Video processing can take 5-30 seconds depending on original file resolution and quality settings.

Cache efficiency

Cached video transformations are served in under 50ms, making caching essential for performance.

Storage impact

Higher quality settings result in larger file sizes. Balance quality against storage costs.

Bandwidth usage

Consider delivering lower resolutions to mobile devices to reduce bandwidth consumption.
Avoid on-demand video transformations for high-traffic scenarios. Pre-process videos during upload or content ingestion whenever possible.
