Auto Video Thumbnail Generator

Auto Video Thumbnail Generator

Generate YouTube thumbnails from any video file or topic with Gemini AI. Upload an MP4, MOV, or AVI, or type a topic, and get up to 10 unique thumbnails in 16:9, 9:16, 1:1, and more. No design skills needed. Export as image files.

Making a click-worthy thumbnail for every video is slow, and hiring a designer for each upload gets expensive. This Actor reads your video file or a topic you type, analyzes it with Gemini AI, and returns ready-to-use thumbnails in the aspect ratio you need. Upload a reference image to match your brand style, or add custom instructions like 'make it colorful and energetic'.

Troubleshooting

Why am I getting an error about missing input?

You must provide either a video file URL or a main topic. If both are empty, the Actor cannot generate thumbnails. Add one of them and try again.

The generated thumbnails don't match my brand colors.

Upload a reference image that represents your brand style. The AI will adapt colors, composition, and mood to match that reference.

I asked for 10 thumbnails but got fewer.

Check the numberOfImages input. It must be between 1 and 10. If you set it to 10, the Actor will generate 10 unique variations, but generation may take longer.

The thumbnail looks blurry or low quality.

Use a higher quality reference image and ensure your video file is not heavily compressed. The AI generates thumbnails at a standard resolution, but input quality affects output.

Can I use a YouTube URL instead of uploading a file?

No, this Actor requires a direct video file upload or a main topic. To get thumbnails from a YouTube URL, use the YouTube Scraper Actor to download the video first, then pass the file to this Actor.
