The models, on one balance
No single model wins every prompt. One holds a face steady, another handles camera movement, another is cheap enough to try an idea ten times. Running them in one place means comparing them is a dropdown rather than five subscriptions.
- Sora 2, OpenAI
- Veo 3 Fast, Google
- Kling V3 Turbo, people who stay themselves as they move
- Seedance 2.0, ByteDance
- Hailuo 2.3, expressive movement and camera work
- LTX-2 Pro, longer takes
- Pika 2.2, clean, well composed shots
- Pixverse V6, the cheapest way to test an idea
Prices differ by model and by clip length, and the playground quotes the exact cost before anything runs. The full lists with the price of a clip on each are on text to video and image to video.
Find the idea cheap, finish it on a strong model
The expensive part of AI video is not the final render, it is the ten attempts before it. Test the prompt on a model that costs 3 credits a second until the wording is right, then spend on Sora 2, Veo 3 or Kling once. Runs that fail are refunded.
Longer than ten seconds
Most video models stop at 10 or 15 seconds a generation. For a longer piece, Percify plans several clips as one story and stitches them, so a long AI video of up to 60 seconds comes from one prompt without drifting between clips.
When the video needs to speak
Generating a scene and making a person say specific words are different jobs. For speech, generate a voice with the AI voice generator and lip sync it to a photo with a talking photo, from 2 credits a second.
