A short demonstration is easier to interpret when you first look for the setup: the workpiece, its position, and the operator's visible checks. Those details provide context for a result frame that might otherwise look more conclusive than the clip supports.
Treat a clip as a review prompt
Pause on the first setup frame and the final result frame, then list what is shown and what is not. A video can document a moment in a prototype workflow; it does not by itself establish final specifications, repeatable output, or delivery timing.
