A practical method
- Identify the film's central visual promise.
- Choose one focal element and remove competing detail.
- Review the thumbnail beside the title for combined meaning.
An example brief to adapt
Write a thumbnail brief for a fictional lighthouse short. Focus on the small lamp in the window, which is central to the story. Do not add a famous actor, invented award or misleading dramatic event. Any text will be added and checked separately.
Review before moving on
- Is the focal point readable at small size?
- Does the image match the film?
- Do title and thumbnail imply an unsupported claim together?
Record a concrete observation beside each check: a line in the treatment, a source passage or a timestamp in the downloaded film. If you cannot inspect an item yet, leave it open. A request in a brief is an intention; the result is what must be reviewed.

What to avoid
An attractive generated image can still be a poor thumbnail if it advertises a different story. Judge relevance before visual polish.
