How it understands your video
You can describe the video in a few words, add your thumbnail, or add the video itself. When you add a video, your browser takes 6 frames from across the video with their times and sends only that one picture to the AI. The video file is never uploaded, so even big files work on a phone.
Advanced description and chapters (timestamps)
Chapters split your video into sections on the progress bar and can appear in Google search. YouTube shows them when the description has timestamps that follow its rules: the first is 0:00, there are at least 3, they go in order, and each chapter is at least 10 seconds long. The tool checks these rules for you and warns you if something needs fixing.
For exact timestamps
Paste your key moments ("0:00 intro, 1:20 warm-up…") or your script in the Key moments box. Without it, AI suggests chapters from the video frames, so check each time before you publish.
Edit before you publish
- Title: tap another idea or type your own; the counter turns orange above 70 characters.
- Description: edit freely and replace [add your links] with your real links.
- Tags: remove with ✕, add your own, and watch the 500-character counter.
- Copy each part or everything at once, then paste into YouTube Studio.
