Grok Video: what it does, what it costs

The budget end of the models where you pick the length, and the only one we price at 480p.

Grok Video is one of the models you can run inside UGC Vids AI. It is made by xAI, renders clips up to 10 seconds, and we price it at 480p and 720p. A render costs 50 to 140 credits depending on the length and resolution you pick, all from the same credit balance as every other model in the catalogue. Everything on this page is generated from the pricing table the app charges against.

What Grok Video is

Grok Video is xAI's video model, taking a reference image plus a prompt. It tops out at 720p: the model has no 1080p mode at all, so this is a genuinely lower-resolution option rather than a discounted version of the same render. We price it at 5s and 10s across 480p and 720p, which makes it the cheapest per second of the models where you choose the clip length.

Where Grok Video fits, and where it does not

Good for

Cheap iteration on a prompt before spending on a higher-resolution model
Feed-only cuts where 720p is enough
The 480p tier, which no other model here offers

Limits

No 1080p and no 4K: 720p is the hard ceiling on this model
Priced at 5s and 10s only, up to 10 seconds
Requires a reference image

Choose Grok Video to iterate cheaply on a scene, then re-render the winner on a model that can deliver 1080p or 4K.

Grok Video: frequently asked questions

How much does Grok Video cost per render?

Between 50 and 140 credits, across 480p and 720p at 5s and 10s. The full table is on this page.

Does Grok Video support 1080p?

No. The model itself has no 1080p mode, so 720p is the ceiling and a request above it is not valid. For 1080p or 4K, use Kling 3.0 or Seedance 2.0.

How long can a Grok Video clip be?

We price 5s and 10s, up to 10 seconds.

Grok Video or Veo 3.1?

Veo runs to 1080p and generates audio with the picture, but caps at 8 seconds, the shortest ceiling of the models where you pick the length. Grok runs longer clips at a much lower credit cost and cannot exceed 720p. Use Grok to find the shot, and Veo when the resolution has to hold up.

Can I use Grok Video on the free trial?

Grok Video runs during the free 3-day trial. Trial renders are capped at 250 credits each, and Grok Video starts at 50 credits. Inside that ceiling the trial covers 5s at 480p for 50 credits, 5s at 720p for 70 credits, 10s at 480p for 100 credits and 10s at 720p for 140 credits.
