Frequently asked questions
How long can the video be?
The tool analyses the first 15 seconds of a clip. Longer videos are trimmed automatically.
Is my video uploaded to a server?
No. The analysis runs inside your browser, so the video stays on your device.
Which AI video generators can I use the prompts with?
The prompts are written in plain descriptive English, so they work with text-to-video tools such as Veo, Sora, Kling, Runway and Pika.
Why are some prompts quite generic?
The detector recognises about 80 common object types plus colours and lighting. For the best result, edit the prompt and add the action, camera movement and mood you want.
