youtube-thumbnail

Design three 1280x720 YouTube thumbnail variants for a finished film as HyperFrames compositions, render them as stills with the motion pack, check them against YouTube's overlay zones and at phone size, and record them in receipts/publish.json. Use when a title is chosen and someone says make the thumbnail, design the cover, give me thumbnail options, or set up a thumbnail A/B test. Not for the title or description (youtube-package) or the upload (youtube-studio-upload).
