API prices are for prepaid API keys; the 6-second column is what one clip of that length costs at the model's lowest resolution. In chat and Studio, generations use your plan's allowance.All API prices
How it works
From an idea to the clip, in three steps.
Start from words or a picture
Describe the shot, animate a photo, or set the first and last frame.
Choose model, length and shape
Choose from 6 video models, then the resolution, length and aspect ratio.
Watch, change, reuse
Ask for a new version in the same thread. Every clip is kept in your media library.
Use cases
What people make with AI video.
A few of the jobs AI video does well, with the Studio preset that does it in one step.
Bring a photo to life
Animate a still image with a slow push-in, an orbit or a drone reveal.
Product videos
Circle a product or glide past it for a store page or an ad.
Social clips
Short clips in vertical, square or wide shapes, with effects like colour bursts or levitation.
Transitions
Morph or whip from one picture to the next for reels and intros.
Cinematic shots
Direct a shot by choosing the camera, lens, focal length, aperture, grade and genre.
Storyboards and ads
Try ideas quickly from text, then ask for a new version in the same thread.
For developers

Questions, answered.
What is the best AI video generator?
It depends on what you are making. Vani puts Seedance and Grok Imagine in one place, so you can try the same idea on several models and keep the result you like. The comparison on this page shows what each model does, its API price and how long it typically takes.
Is the AI video generator free to use?
You can start free: video generation is included on every Vani plan, Free too, and uses your plan's allowance. Paid plans give you more room. On the API, videos are billed per second or clip from a prepaid balance instead.
Can I turn a photo into a video?
Yes. Upload a photo in chat or Studio and describe the motion. Grok Imagine Video 1.5, Seedance 2.0 Fast VIP, Seedance 2.0 Mini, Seedance 2.0 VIP and Seedance 2.5 animate still images. Some models also let you set the first and last frame.
How long can the videos be?
From 1 second to 30 seconds, depending on the model, at up to 4K. Each model's page lists its lengths, resolutions and aspect ratios.
Is there an AI video generation API?
Yes. Every model on this page is on the Vani API with a prepaid key: POST /v1/videos. Video is priced per second or per clip. A video is created as a job; poll it, then download the file. A failed generation is not charged.
