Video thumbnails
Find a thumbnail instead of guessing a timestamp
A useful thumbnail should be sharp, readable at small sizes, and representative of the video. Count mode samples the selected range evenly, giving you a faster first pass than scrubbing the entire clip.
After comparing candidates, you can capture a nearby exact timestamp or download the strongest image directly. The contact sheet keeps the whole selection visible in one file.
