Each clip costs credits based on the model, the resolution and the length. Grok Imagine starts at 5 credits, Veo 3.1 Fast costs 17 at 720p, and the most detailed settings cost more. The exact total shows on the Generate button before you click.
Veo 3.1 and Gemini Omni charge per clip, so a longer clip costs no more. The other models charge per second, so a 10-second clip costs about twice a 5-second one.
Credits come from your TurboCast plan and are shared with images, text to speech and voice cloning. Starter includes 300 credits a month. That covers 17 eight-second Veo 3.1 Fast clips, or 37 six-second clips on Grok Imagine at 720p.
Credits are reserved when a clip starts. If it fails or the model refuses the prompt, every credit returns to your balance automatically.
The AI video generator is part of every paid plan rather than a free tool. That keeps the queue short, files watermark-free and commercial use included.
