--- name: check-video-frame-rate category: media description: Check source, sequence, shutter, playback, and delivery frame rates for intended motion and synchronization. Use when footage may stutter, drift, interpolate, or change speed unexpectedly. --- # 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
