👍 How do I create a thumbnail for my video?

Create Thumbnail generates a ready-to-use thumbnail straight from your video's own images, so you don't need a separate design tool. It lives in the Export panel under Other Actions.

Create a thumbnail

1. Click Export in the top-right, then click Create Thumbnail under Other Actions.
2. (Optional) In Describe the thumbnail, add direction for the look, e.g. "Bold title text, dramatic lighting, surprised expression."
3. Under Select pictures you want to use to create a thumbnail, tick the scene images you want the thumbnail based on. (There's a per-model limit, e.g. up to 14 images for Nano Banana 2.)
4. Choose a Model from the dropdown (default: Nano Banana 2).
5. Click Create Thumbnail. The button shows the credit cost (e.g. 2 credits).

Each run produces one thumbnail. Want options? Run the flow again, tweak the description or swap the selected images, to generate more.

Review past thumbnails

Click See History (top-right of the Export or Create Thumbnail panel) to see every thumbnail you've generated, handy when you've created several and want to compare and pick the best.

💡 Tips:

• Select a few strong, on-character images rather than every scene, tighter input gives a cleaner result.
• Use the description box to add a title or set the mood; leave it blank to let the model choose.
• Generate a few variations and compare them in See History before choosing.
