Check which frames the analysis actually received. A fast gesture can fall between sampled frames, so a summary may describe the surrounding poses while missing the event itself. Inspect the source around the gesture, record a short visible interval and use a supported video or frame-input method with adequate coverage. A timestamp written in a prompt does not give a model visual evidence it never received.
Identify an observable event
Choose a gesture with a clear beginning, peak and end, such as a clap or hand crossing the chest. Note the source timeline and inspect adjacent frames in a capable video editor. Avoid assigning an exact joint position to a hand hidden by another person or blurred beyond recognition.
Different analysis and generation systems sample video differently. Check the actual API or interface contract, including duration and frame handling where documented. Do not infer dense motion capture merely because the request accepts a video filename or returns a detailed paragraph.
Expand evidence around the missed beat
- Locate the gesture in the source editor at normal speed.
- Inspect its onset, peak and release in neighboring frames.
- Record the short interval and the evidence available at each point.
- Supply that interval or reviewed frames through supported inputs.
- Check whether the revised analysis names the correct visible action.
The next question is whether the generator follows that evidence. Keep analysis accuracy and output movement as separate checks. A complete written description can still exceed a chosen model’s motion-control capability.
Avoid false precision
Do not convert a sparse frame summary into a claim of exact choreography or recovered skeletal motion. Runway’s performance-capture guide describes a driving-video workflow, but does not establish the behavior of unrelated video-summary channels. Evaluate the actual system at the actual gesture.
Should I slow the source down before analysis?
That can make events easier to observe, but changes the apparent duration. Record the speed change and keep the original timing for reproduction. Do not hand a slowed interval to a generator while claiming its actions are already synchronized to the original music.
Is a missing gesture always a sampling problem?
No. Occlusion, blur or model interpretation can also be responsible. Start with the received visual evidence, then investigate the next stage. Keep the reference excerpt so another reviewer can reproduce the diagnosis.
