Video thumbnail
Bold uppercase title over a photo, a highlighted second line, channel and duration — YouTube style.
Creator thumbnail
A face cut out with a white outline, two to four huge words, a yellow highlight and an arrow.
Tutorial thumbnail
How-to video thumbnail: a screenshot in a tilted app window with a marker circle and a curved arrow on the spot that matters, the tool's logo on a big tile and a bold promise next to it.
Gaming thumbnail
Gaming video or stream thumbnail: the character large with a hard rim light, the title on a slanted band, the episode number, and the rank on a gold shield.
Reaction thumbnail
YouTube reaction thumbnail: the thing you react to in a torn paper frame, your face in a big ringed circle, two or three words in heavy outlined type over rays in the accent colour.
Livestream
A glowing LIVE badge, the start time in a monospace face, the stream title and a player frame with your image.
