Detect Motion
Detect Motion finds moving and still stretches in video. Run it before Delete Non-motion or Camera Selection needs that information. Detect Motion itself doesn't edit the timeline.
Analyze video
- Select video files in the media bin or select clips on the timeline.
- Open the Process menu and click Detect Motion…. You can also right-click selected files in the media bin and choose Detect Motion….
- Choose Selected in Bin or On Timeline, then check the files you want to analyze. Audio-only files aren't supported.
- Keep Motion Type set to Auto unless it identifies the footage poorly. In that case, choose Screen, Camera, or Hybrid and run it again.
- Click Run Detect Motion.
For cancellation and errors, see Run an AI Tool.
Detect Motion looks for visual change, not what caused it.
Review the result
To see the analysis on the timeline, right-click a clip, open Display, and click Motion Overlay. You can also right-click an empty part of the timeline and choose Motion Overlay. The colored bars show how much the picture changes across each analyzed clip, which makes moving and still stretches easy to compare. This setting applies to the whole timeline and stays on between sessions.
To check a file's summary, right-click it in the media bin and choose Module Results. The Motion row shows the detected footage type and the number of motion segments.
Use the result
- Clip → Delete Non-motion… uses the analysis to find still stretches. You can disable those stretches or delete them from the timeline, so check the highlighted regions before applying the change. See Cut Silence and Dead Footage.
- Camera Selection uses motion as one clue when choosing which camera to show. In its camera list, the monitor icon means that lane has motion data. See Pick Camera Angles with Camera Selection.
