AI video generator

imaginary.app turns a written prompt, or with Veo 3.1 a photo, into a short video clip, with sound if you want it. Pick a model, set the format and length, see the credit cost, then generate. If a generation fails, its credits come back.

Key takeaways

  • Model: Google Veo 3.1, in three variants (Lite, Fast and Quality).
  • Veo 3.1 clips are 4, 6 or 8 seconds, in 16:9 or 9:16, at 720p or 1080p, plus 4K on Fast and Quality.
  • A Veo 3.1 clip costs 1 to 38 credits; credit packs start at $9.99, with no subscription required.
  • Failed generations return their credits automatically.

Write a prompt and generate your first clip

Choose a model and settings, see the credit cost before you start, and get the credits back if a generation fails.

What you can make

An AI video generator is strongest at short, single shots: one subject, one action, one camera move. That covers more than it sounds like. People use ours for:

  • Product and ad shots. A slow push-in on a bottle, a phone turning on a plinth, a hero shot animated from your own product photo. See AI video for product ads.
  • Vertical social clips. 9:16 shots with sound for Reels, Shorts and TikTok; our social shorts guide covers hooks and pacing.
  • B-roll and explainers. Establishing shots, cutaways and scene-setters to cut between talking segments or slides.
  • Short dialogue scenes. Veo 3.1 generates speech, effects and ambience with the picture. Put the spoken line in quotes and say who speaks it.

For ready-made starting points, browse the prompt library or real clips other people shared in the public gallery.

How it works

  1. Sign in with Google

    Creating an account is free and needs no card. You buy credits only when you want to generate.
  2. Write your prompt

    Describe the subject, the action, the setting, the camera and, if you want sound, what we should hear. Prompts can be up to 2,000 characters. With Veo 3.1 you can also start from an uploaded image, or give a first and last frame.
  3. Choose a model

    Veo 3.1 Fast is the default. Lite is cheaper for drafts and Quality is for final renders.
  4. Set the format

    Pick the aspect ratio, resolution, clip length and whether to generate audio. The options shown are the ones the selected model supports.
  5. Check the cost and generate

    The generator shows how many credits the clip will cost before you start. Credits are taken when the generation starts and returned automatically if it fails.
  6. Download the result

    Finished videos are saved to your account, where you can watch and download them.

Choose a model

Veo 3.1 comes in three variants. Starting prices are each variant’s lowest setting (a 4-second silent 720p clip); the generator shows the exact cost for your settings.

What it costs

You pay per clip in credits. A credit costs $0.21 to $0.25, depending on the pack or plan you buy it with, and the smallest one-time pack is $9.99. On Veo 3.1 a clip costs 1 to 38 credits depending on the variant, resolution, length and audio; an 8-second 1080p Veo 3.1 Fast clip with sound is 10 credits ($2.13–$2.50). Full tables are on the pricing page and in the Veo 3.1 cost calculator.

We are not the lowest price per second for Veo 3.1: Google Cloud's own list price is lower if you set up a Cloud project and billing yourself. What you get here is no Cloud setup, one-time packs instead of a monthly plan, and automatic refunds on failures.

If a generation fails

Credits are taken when a generation starts. If it fails, the credits for that generation go back to your balance automatically. You only pay for videos that finish.

When another tool may suit you better

  • You need a single continuous take longer than 8 seconds. Some other video models generate longer clips in one pass; see our model comparisons.
  • You generate at high volume and can manage Google Cloud billing yourself: going direct to Google costs less per second.
  • You only make a few clips a day: Google Flow's free daily credits may be enough. Our alternatives guide compares the options honestly, ours included.

For developers

Veo 3.1 Lite, Fast and Quality are also available through our REST API with a veo_ API key; credits and refunds work the same way. See the API documentation.

Frequently asked questions

Is this AI video generator free?

Creating an account is free: you sign in with Google and no card is needed. Generating a video uses credits, which you buy in one-time packs from $9.99 or with a monthly plan.

Can I turn a photo into a video?

Yes, with Veo 3.1. Upload a starting image, or a first and last frame, and describe the motion. Lite, Fast and Quality all support it.

How long can the videos be?

Veo 3.1 makes 4, 6 or 8 second clips. For longer videos, generate several shots and edit them together; first-and-last-frame helps one shot pick up where the previous one ended.

Do the videos have sound?

Veo 3.1 can generate dialogue, sound effects and ambient audio with the clip, and you can switch audio off for a silent clip that costs fewer credits.

What happens if a generation fails?

The credits for that generation go back to your balance automatically. You only pay for videos that finish.

Can I use the videos commercially?

Our Terms of Service allow personal and commercial use of the videos you generate, subject to the restrictions in those Terms. Read them before you publish, along with any rules that apply to the content itself.
