Quick answers to the questions that come up most often. For deeper explanations, follow the links into the rest of the docs. ## What is Ozu? Ozu is an AI-powered pre-production tool for filmmakers. You paste a screenplay and Ozu generates a complete pre-production package: Actors, Props, Sets, a shot-by-shot storyboard of Frames, and a rough-cut Animatic. Script in. Animatic out. ## Who is Ozu for? Filmmakers, directors, animators, and creative professionals who need to visualize a film before they shoot it. Independent filmmakers who can't afford a full art department, and professionals who want faster iteration on pre-production. ## What script formats do you accept? Standard screenplay format — Final Draft (.fdx), Fountain (.fountain), and plain text. The script should follow standard INT./EXT. scene header conventions. Features, shorts, music video treatments, and commercial scripts all work. ## How does the pipeline work? Ozu breaks your script into Scenes, Shots, and Beats. Each Beat becomes one Frame in your storyboard. Along the way, Ozu auto-creates Actor, Prop, and Set nodes for every named character, object, and location so your visuals stay consistent across the whole project. For the full walkthrough, see [Getting Started](/user/getting-started/) and [Scene, Shot, Beat](/user/concepts/scene-shot-beat/). ## Do I have to use every node? No. The pipeline runs end-to-end from script to Animatic on its own. You can intervene at any node to adjust, reframe, or regenerate — or let Ozu take the whole trip in one pass and review at the end. ## Who is Ozu? Ozu is the AI assistant director. He reads your script before the pipeline runs, surfaces visual gaps, reviews generated assets against script descriptions, auto-drafts prompts for image generation, and runs quality checks at every stage. He carries the full context of your project across sessions. ## How does Camera Control work? Your approved Set panorama converts to a navigable 3D Gaussian splat. You load into it with familiar 3D viewport controls — orbit, dolly, pan — and frame your shot in real 3D space. Actor pins mark where characters stand. When you capture, the clean screenshot (no UI, no pins) feeds image generation. ## How do Credits work? Every AI generation operation consumes Credits. Verifying your email on signup grants 200 free Credits — enough to take a short scene from script to storyboard. For ongoing work, paid tiers refill a monthly allowance. See [Credits and Quotas](/user/troubleshooting/credits-and-quotas/) for the full breakdown. ## Do unused Credits carry over? On the free tier, the 200-Credit grant is one-time and doesn't refill. On paid tiers, the monthly allowance refills each billing period — check the tier details in the upgrade modal inside the app for carry-over rules. ## Can I buy additional Credits? Yes. Additional Credits are available as one-time top-up purchases at any time, regardless of your tier. ## Do you use my content to train AI models? No. Your scripts, generated images, project data, and creative content are never used to train AI models. ## Do I own the content I generate? Yes. You own your generated outputs. Ozu does not claim ownership of your characters, storyboards, environments, or other assets. The copyright status of AI-generated works is still evolving. Check Ozu's [AI Content Policy](https://ozu.studio/legal/ai-content) for the latest guidance. ## What happens if a generation fails? Ozu doesn't charge you for failed generations. Credits are held when a job starts and released (not debited) if it fails. You'll see a status indicator on the node — retry from there. For common failure modes, see [Generation Failed](/user/troubleshooting/generation-failed/) and [Safety Blocks](/user/troubleshooting/safety-blocks/). ## Didn't find your answer?
