AI Storyboard Generator: Turn Your Story into a Long AI Video, Scene by Scene

Most AI video generators stop at a single clip of a few seconds. Proxima Storyboard builds a whole film: write a story, let the AI split it into panels, draw every scene with your own characters and then animate the panels one by one into a continuous movie. You review each result and shape the final edit as you go.

Because the film is assembled scene by scene, the method has no hard length ceiling — in theory it scales to films of up to half an hour.

Two Storyboard Modes: Panels and Sheet

• Panels mode — full control. Every scene is a separate panel with its own image prompt and video prompt. You generate, preview and regenerate each scene individually and approve the takes you like.
• Sheet mode — the fast way. The whole story is drawn as one storyboard sheet, and the Convert to Movie button turns it into a video in a few clicks, with less control over each shot.

How to Make a Longer AI Video with Proxima Storyboard

Here is a simple step-by-step guide for Panels mode. Create your film one scene at a time, review each result and shape the final edit as you go.

1. Select the Panels storyboard mode.
2. Choose between 4 and 16 panels. We plan to increase this limit in the future.
3. Write your story in any language.
4. Select 1–3 characters (see consistent characters). If you haven't created any characters yet, make them first in Character Asset Pack. You can also try a storyboard without character tags.
5. Optionally, upload visual references such as locations, objects or other elements.
6. Add a short description to each visual reference to explain what it represents.
7. Go back to the top and click Enhance. The AI expands your story across the panels and writes image prompts for the scenes, including the relevant character and visual tags.
8. Choose an image model at the bottom. Qwen 2.1 works especially well with multiple references, but you can also use Krea 2 and LoRAs.
9. Review and edit the image prompt of each panel. Click Draw to generate panels one by one, or Compose to generate them all at once.
10. Once the storyboard images are ready, the video settings appear at the bottom. Choose the resolution, LoRAs and other options.
11. Switch to video mode with the video camera icon. For each panel, click the magic wand to generate the prompt for that video scene, then click Generate Video.
12. After generation, preview the single scene and the full edit with all scenes generated so far. Approve the result or regenerate it.
13. Repeat for each panel until your storyboard film is complete.

For the most control, review and refine each scene as you go. For speed, you can also build a storyboard in just a few clicks — with less control over the result.

Smart Prompts for Every Scene

The magic wand in every panel is a prompt enhancer: it takes all the available context — your story, the scene, the characters and references — and writes the video prompt for Minimax H3 for you. You can edit it, or just press Generate.

Pro Video Settings: LoRAs, Resolution, Takes

• Minimax H3 LoRAs — improve dynamics, image quality and camera movement right in the storyboard video settings.
• Up to 2K resolution — every scene is animated and joined with the previous one, so the film flows as one continuous take.
• Several takes per scene — regenerate a scene, compare the variations and keep the one you like best.

Who It Is For

• Short films and music videos — pre-visualize every shot and turn it straight into video.
• Social media series — tell a story across several clips with the same characters.
• Comics, picture books and pitches — get a consistent sequence of panels in one style.
• Ads and product stories — build a short narrative around a product or a mascot.
