- Tennis players reviewing serve or stroke technique
- Worth noticing
- Its instructions focus on comparing movement principles, not matching identical poses, and say different frame rates need no playback adjustment.
Field notes
Each side has independent controls, while a Sync tab plays the clips together; users can adjust playback from ¼× to 4× and loop the aligned interval. The instructions cover zooming, panning, fullscreen inspection, and frame-specific pen or arrow annotations with separate undo histories. Serve presets are pre-marked, but newly added library clips may need contact markers; local recordings are described as staying on the user's device.
