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.
How long does it take to generate a video?
Grok Imagine Video 1.5 typically finishes in about 40 seconds. Typical times are the median of recent successful generations on Vani; longer clips take longer.
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 and Seedance 2.0 VIP animate still images. Some models also let you set the first and last frame.
How long can the videos be?
From 1 second to 15 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.
What are camera moves and effects?
They are ready-made presets in Vani Studio: 64 camera moves, 105 effects and 20 transitions, such as Dolly In, Living Memory and Morph. Pick one, add your photo or a few words, and Studio writes the prompt for you.
