Video thumbnail: caption, update and AI thumbnail

The finished video page has a thumbnail block. What you can do there: • “Thumbnail hook caption” — a catchy text on the image. A long text is wrapped automatically into 2–4 lines so it does not run off the edges. • “Update thumbnail” — the same frame with the new hook text (even if you have not pressed “Save” yet). • “Another frame from the video” — picks a different random frame. • “Generate thumbnail with AI” — choose a model (for example Ideogram or Nano Banana) and the AI draws a juicy, clickable thumbnail from the title, description and hook. You do not write a prompt. This is a paid operation: it is charged from the AI balance like a regular AI image; if the model fails, nothing is charged. • “Upload your own thumbnail” and “Download thumbnail”. Note: YouTube does not let our channel upload thumbnails via the API, so YouTube uses an auto-cover from a video frame by default. You can download the thumbnail here and upload it to YouTube manually. The “Regenerate description/hashtags/hook” button recreates only the texts — the footage does not change. To get a different video with the same settings, use “Repeat” in the “Parameters” panel.
