Which model to use
- Testing an idea. Pixverse V6 at 3 credits a second. Five seconds costs about 25 cents, so you can try the same shot six ways for the price of one premium take.
- A person in the frame. Kling V3 Turbo keeps a face recognisable through the movement, which is where cheaper models drift.
- Lively motion. Hailuo 2.3 moves the subject and the camera more than most, for about 48 to 73 cents a five second take.
- The best take. Veo 3.1 Fast and Sora 2. Veo also generates its own audio, and its 4K costs the same as its 720p.
- 720p without a multiplier. Wan 2.7 starts at 720p rather than charging a multiple to get there.
Every model runs on the same credits and the same API key, so changing model is a parameter, not a migration. API pricing.
Make it move, or make it talk
These models animate a picture. They do not make the person in it speak: lip sync is a different family of models, driven by an audio track, where the mouth and jaw follow the voice. If what you want is a photo that says something, start at make a photo talk, which runs from 2 credits a second. If you want the photo to move, stay here.
Watermarks, rights and consent
- No watermark on any plan, including the free one.
- You own the content you generate, under Percify's terms. It is not exclusive: similar inputs can give similar output for someone else.
- Use your own image, or one you have the rights to. A photo of a person needs that person's agreement.
