Frequently Asked Questions

  • What is Grok Imagine?

    Grok Imagine is xAI's video generation model. On MakeFun AI it runs in the browser in both text-to-video and image-to-video mode, so you can generate from a prompt alone or animate an image you upload.

  • How long can a Grok Imagine clip be?

    6, 10 or 15 seconds. Shorter clips return faster and cost fewer credits, so it is worth locking the prompt at 6 seconds before spending credits on a 15 second render.

  • Do I need an image to use Grok Imagine?

    No. Text-to-video works from a written prompt alone. Upload an image only when the opening frame matters — a product, a portrait, or a scene that has to match something you have already made.

  • How do I write a prompt that works on the first try?

    Name the subject, the action, the setting and the camera behaviour in that order, and keep one idea per clip. Vague mood words produce generic motion; concrete verbs like walks toward, tilts up or pushes in do not.

  • Do I need to sign up, and is it free to try?

    You can start for free. New accounts get bonus credits on signup, there is no credit card required, and the free plan has no daily generation limit. You can also claim extra credits every day by checking in. Everything runs in the browser on MakeFun AI — no GPU, no install, and no API key.

  • Can I use the videos I generate for commercial projects?

    Yes. Videos generated on a paid MakeFun AI plan can be used commercially — ads, social media monetization, client deliverables and product marketing. You keep ownership of the output, with no watermark, no attribution requirement and no per-clip royalties.

  • Where do my videos go after generation?

    Every finished job appears in the My Results tab beside the generator, where you can preview, download, share or delete it. The list keeps the last 3 days of generations, so download anything you want to keep before it rolls off.
