Common questions about Thumio
Thumio can now build a thumbnail from a YouTube link, including Shorts.
Paste the URL, and Thumio says it watches the full video, picks out the hook and key moments, writes a title, and uses a photo from your library in the thumbnail. You don't need to upload the video or find a frame yourself.
