# check-video-frame-rate
Separate capture rate, playback interpretation, timeline rate, and export rate.
## When to use
- Use before production, ingest, editing, slow motion, multicamera sync, or delivery.
- Preserve originals before changing metadata or interpreting a clip.
## Procedure
1. Record required delivery frame rate, regional power frequency, motion style, slow-motion plan, audio-sync needs, and platform limits.
2. Inspect each camera's nominal and actual rate, variable-frame-rate status, shutter, time base, audio sample rate, and metadata.
3. Confirm the editing sequence and playback interpretation explicitly.
4. Decide whether off-rate footage plays real time, conforms for slow motion, drops or repeats frames, or needs high-quality conversion.
5. Test long clips for drift and motion cadence, not only the first seconds.
6. Export a representative motion and lip-sync sample at the delivery rate.
7. Document every conversion, interpolation, conformance, and exception.
## Done
- A frame-rate report lists source, actual rate, interpretation, sequence, shutter, audio, conversion, and delivery decisions
- Test export playback verifies real-time speed, intended slow motion, cadence, lip sync, and long-duration stability
