Detailed result requirements

Required inputs

Original image of video character or theme object + video theme or title → Generate high-contrast composition and title area → Current single YouTube Thumbnail

Input quality

No universal public standard is available. Check the requirements of the platform or service you will use.

Composition

No universal public standard is available. Check the requirements of the platform or service you will use.

Output aspect ratio

Set the output canvas from the selected platform placement or production template, not from a reference image. Choose the option that matches this request: standard YouTube video thumbnail — 16:9 (recommended); YouTube Shorts thumbnail — 9:16 (recommended); YouTube Podcast Playlist Cover — 1:1 (required). Choose the target aspect ratio before generation; do not default to 1:1. Use a custom ratio only when the actual placement or production template requires it. Choose the video-asset type first. Standard video, Shorts, and podcast-playlist artwork are three separate deliverables. Create one aspect-ratio-specific deliverable per request; generate each additional placement as a separate output. Recompose for the selected ratio while preserving the complete subject, all text, and every required safe area. Never stretch the subject or treat cropping important content as adaptation.
