3D Shorts Explainer

3D Shorts Explainer turns a topic into a vertical 9:16 short: a hook, four to eight shots, narration, music, and captions. The script is approved before any image credits, and the look is approved before any video credits. Check facts before publishing.

Flow

Create, then Script, Look, Render, and Done. Keyframes use a locked character's reference stills when you pick one. Motion defaults to Seedance 2.0 Fast (bytedance/seedance-2.0-fast). Other catalog models are allowed. A failed stage retries without redoing earlier stages.

API

The studio route is POST /api/explainer-shorts. /api/3d-shorts is the public alias. It returns 202 with project_id and state: scripting. Poll GET /api/explainer-shorts/:id. Length is 15, 30, 45, or 60 seconds. Credits follow max(1, round(provider dollars × 250)) when a provider price is known. Keyframes are 8 credits each. Voice is 4.
