Genjutsu - AI Model API and Pricing

What recasting a clip means

Genjutsu keeps the motion, camera and timing of the clip you give it and swaps what is in it. A walk-and-turn filmed on your phone can become a model in a new jacket. The same hand gesture can hold a different product, and a street can become a beach.

It accepts up to eight reference images in one run. Use them to pin down the new subject from several angles, such as front, side and back. Add a close-up of any logo or texture that must stay exact.

How to run it

Open Genjutsu in the video to video AI tool. Upload your source video and up to eight reference images. Add a short note if you want, and pick 480p, 720p or 1080p. The price shows as soon as the clip is uploaded, before you start.

Rules your source clip must follow

Length comes from your clip, not from a setting. The source must be at least 4 seconds, and anything over 30 seconds is cut to 30. Trim before you upload, because you pay for every second that goes through.

Pick clips with clear, readable motion and a subject that stays in frame. Here is a prompt that works alongside the references. "Replace the runner with the woman in the reference images, same red track jacket. Keep the park but make it autumn."

The most expensive option, so budget carefully

The rate is 205 credits per second at 1080p, 87 credits at 720p and 41 credits at 480p. A 5-second clip at 1080p costs 1,025 credits, about $10.91. A 10-second clip costs 2,050 credits, about $21.82.

Cheaper routes exist. Kling 3.0 Motion Control at 27 credits per second makes one character from a photo perform the motion from a clip. Kling 3.0 at 27 credits generates new 1080p clips up to 15 seconds with reliable object handling. Seedance 2.5 at 27 credits makes 30-second takes with synced dialogue.
