Tips

Prompt Suggestions:Use specific and vivid descriptions, including actions, scenes, lighting, etc. Avoid vague expressions.
Model Selection:Fast mode generates quicker, Quality mode produces better results but takes longer. Choose based on your needs.
Seed Value:Using the same seed value with the same parameters can reproduce similar results, useful for fine-tuning and iteration.

Frequently Asked Questions

  • Which modes does Google Veo 3.1 support here?

    Three: Text, which needs only a prompt; Image, which takes a start frame and optionally an end frame; and Reference, which takes 1 to 3 reference images and renders in 16:9.

  • Should I pick Fast or Quality?

    Fast returns sooner and costs fewer credits, which suits iteration and previews. Quality takes longer and produces the better final render. A common workflow is to lock the prompt on Fast, then re-run the winner on Quality.

  • How do I reproduce a result I liked?

    Reuse the same seed value, between 10000 and 99999, together with the same prompt and parameters. That is the practical way to fine-tune one shot without losing the version you already liked.

  • How long can the prompt be, and which aspect ratios are available?

    Prompts are limited to 500 characters, so spend them on scene, action, lighting and camera rather than adjectives. Aspect ratio can be Auto, 16:9 or 9:16, and Reference mode always renders 16:9.

  • 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 β€” 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 β€” 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.
