Quality tiers
Durations
Output duration matches the input clip. Longer clips cost proportionally more credits. StirVid returns a quote before deducting credits; the quote reflects both mode and duration.Sound retention
- Retain: original audio is muxed into the output MP4 unchanged.
- Silent: no audio track written.
Storage
- Rendered MP4s are archived to storage on completion.
- Signed URLs are issued on demand and expire on rotation.
- Job records persist even after the media is archived, so historical generations remain queryable through the Control API and MCP
generation_status.
