An AI director that actually storyboards before it shoots
BigBanana treats AI video generation like animation production—script, assets, keyframes, then motion—instead of praying to the text-to-video slot machine.

What it does
BigBanana AI Director is a browser-based workbench for producing AI short dramas and motion comics. It breaks the pipeline into four phases: narrative planning, consistency asset generation, shot workbench with keyframe control, and delivery with a built-in timeline editor. You can import a full novel and have it auto-split into episode drafts, or build projects manually with seasons and episodes.
The interesting bit
The “Script-to-Asset-to-Keyframe” workflow borrows from traditional animation rather than the usual “prompt and hope” approach. It generates start and end frames first, then uses Veo for interpolation—constraining everything against locked character reference sheets and scene concept art. There’s even a nine-panel storyboard preview to pick compositions before committing to full generation.
Key highlights
- Project-level organization: Hubs for multi-season shows with shared asset libraries and worldview bibles (maps, locations, music style anchors)
- Consistency system: “Costume wardrobe” for characters, reusable prop assets, and batch gap-filling for missing reference images
- Dual video pipelines: Single image-to-video or start/end frame interpolation with context-aware generation that reads scene and costume references
- CutOS timeline editor: In-browser rough cut with reordering, trimming, and filter export to Premiere/Resolve
- Prompt version control: Centralized prompt management with rollback history across all pipeline stages
Caveats
- The public repo is now documentation-only; actual code updates ship via Docker images after plagiarism disputes
- Hard-locked to AntSK API for models (GPT-5.2, Nano Banana Pro, Sora-2, Veo-3.1, etc.) unless you pay for commercial source access
- Project data lives in browser local storage, which is fine until it isn’t
- CC BY-NC-SA 4.0 license means no commercial use without separate negotiation
Verdict
Worth a look if you’re producing serialized AI video and tired of character drift between shots. Skip it if you want hackable open-source code, self-hosted models, or a zero-cost pipeline—the maintainers are explicit that “free as the only standard” users should go use Doubao instead.
