Choose a cover image for video

We have a 45-second behind-the-scenes video of the ceramicist spinning a bowl. Pick and set a thumbnail so the bowl-on-wheel frame with the potter’s hands in motion appears first to viewers, and make sure the image is clear at 1080x1920 for mobile. Use that cover when I publish this afternoon.

Before I set a cover for this studio clip, make the choice easy to approve: surface three candidate frames — the opening wide shot, the mid-action hands-on-wheel, and the close-up of the spinning clay — labeled by timestamp and how they read on a phone. Highlight which frame shows the maker’s face and which reads best at small sizes. Flag any that look blurry or cut off at 9:16.

I just reviewed the ceramicist’s 45-second clip and most candidate thumbnails blur when I view them at mobile size; the only clear frame is a static shot at 00:03 but it doesn’t show the hands. I need a cover that sells the process immediately. Is it better to use the static clear frame even though it’s less dynamic, or pick a slightly blurred action frame that shows hands and add a contrast boost? Which choice likely gets more clicks?

Across a dozen videos I keep losing time debating covers: the team argues over showing the maker’s face, the most dynamic action, or a clean branded frame, which delays posting. What rule or routine should I adopt so covers are decided quickly and consistently — for example, a three-option preflight, a fixed priority (action > face > brand), or a required mobile preview — and how would that change approvals?
