Compare three distinct approaches in words — subject, contrast, text area, background — and render only the one you pick.
One hero subject with real separation from the background, so the image still reads when it is a card on a phone.
Leave with a channel rule, so the next thumbnail is recognizably from the same channel without starting over.
Give a long-form idea a single visual anchor that matches the title's promise instead of restating it.
Put the product where the eye lands first and keep the comparison legible at card size.
Show the result or the moment of difficulty, with clear space for the step count or the outcome.
Keep the face and the scene readable together, with the expression carrying the hook.
Hold one layout across episodes so the series is recognizable in a subscription feed.
Start with the title
Share the promise the video makes, who it is for, and the subject that has to survive into the thumbnail.
Compare before rendering
Each direction names its focal subject, contrast approach, text area, relationship to the title, and background treatment.
Then make it
The selected direction is rendered at 16:9 from your frame or as an original concept, and handed back with its actual dimensions and format.
