Render a thumbnail
Package a finished video with its cover: one frame of it, three to five words, at most one picture, sized for the platform.
It is filed beside the video as <video>-thumbnail.jpg, so a post that carries only the video key gets the cover on YouTube, LinkedIn, Facebook and Reels without another step.
Ask in plain words
- "make a YouTube thumbnail for this video"
- "thumbnail generator API"
- "put a three word cover on my Reel"
