Look for the setup label first
When reviewing a short demonstration, pause before the close-up and look for the label, object, or setup cue that tells you what is being shown. The final visual can be useful, but it needs context to become a meaningful observation.
Write down what is plainly visible and what remains outside the frame. That prevents a short edit from becoming a claim about materials, speed, or included items.

Use timestamps and short descriptions rather than broad conclusions. Related methods for reading evidence are available in /updates/.
