Confirm sources, limits, and output settings before sending the file onward.

Workflow

Decision

Which one should you use?

Use YouTube thumbnail dimensions for the clickable image that represents a standard video in search, recommendations, channel pages, and embeds.

Use YouTube Shorts dimensions for vertical short-form video frames and Shorts-first cover planning. Build a separate vertical composition rather than cropping a 16:9 thumbnail.
