| Story structure | Connected shots with setup, development, and resolution | A foundation for shorter clip creation |
| Reference understanding | Stronger control across subjects, scenes, motion, and sound | Unified multimodal reference foundation |
| Editing direction | Time-range instructions and more targeted changes | Earlier generation and reference workflow |
Direct the whole sequence
The official model focuses on longer storytelling, richer references, and targeted edits across a connected audio-video sequence.
These are official model capabilities. The generator above does not expose separate timeline, green-screen, or camera-control switches.
Long-form storytelling
Organize multiple connected shots inside a 30-second generation while preserving subjects, setting, pacing, and sound.
Multimodal reference
Guide composition, characters, props, motion, voices, and visual language with image, video, and audio references.
Timestamp-based editing
The official model can follow time ranges for targeted changes to actions, shots, and audio-video content.
Production-oriented control
Official scenarios include green-screen editing, camera perspective changes, clay renders, and performance blocking.
Built for stories that need direction
Move from commercial concepts to learning and industrial communication with one consistent creative brief.
Commercial production
Plan product, character, camera, and sound references for connected campaign scenes.
Industrial training
Visualize assembly order, equipment movement, and process demonstrations for training workflows.
Education and explanation
Turn historical events, scientific ideas, and procedures into structured visual lessons.

You can use up to 30 images, 3 videos, and 3 audio files. Reference videos and reference audio each have a combined 30-second limit.
Choose 480p, 720p, or 1080p, one of 7 aspect-ratio options, and MP4 or MOV output.
Yes. The current integration includes options to generate audio, enable web search, and return the last frame.
No. ByteDance describes them as official model capabilities and scenarios, but this page does not expose dedicated timeline, green-screen, or camera-control switches.
