The Key Principle<\/strong>: Use natural language to describe what to extract from which file<\/p>\nAdvanced Example<\/strong>:<\/p>\nReference @Image1 for the man's appearance in @Image2's elevator\r\nsetting. Fully replicate @Video1's camera movements and the\r\nprotagonist's facial expressions. Hitchcock zoom when startled,\r\nthen several orbit shots inside the elevator. Doors open, tracking\r\nshot following him out. Exterior scene references @Image3, man\r\nlooks around. Reference @Video1's mechanical arm multi-angle\r\nfollowing shots tracking his line of sight.\r\n<\/code><\/pre>\n3. Character and Object Consistency (The Identity Lock)<\/h3>\nThe Previous Problem<\/strong>: AI video models struggle maintaining identity across frames\u2014faces morph, products change, details disappear<\/p>\nSeedance 2.0 Solution<\/strong>:<\/p>\nFace Consistency<\/strong>:<\/p>\n\n- Characters maintain exact appearance throughout<\/li>\n
- Facial features stable across all angles<\/li>\n
- Expression changes natural while preserving identity<\/li>\n
- Multi-character scenes keep everyone distinct<\/li>\n<\/ul>\n
Product Detail Preservation<\/strong>:<\/p>\n\n- Logos remain crisp and accurate<\/li>\n
- Text legibility maintained<\/li>\n
- Brand colors consistent<\/li>\n
- Fine details (stitching, textures) preserved<\/li>\n<\/ul>\n
Scene Coherence<\/strong>:<\/p>\n\n- Environments stable throughout<\/li>\n
- Architecture consistent<\/li>\n
- Props maintain appearance<\/li>\n
- Background elements don't drift<\/li>\n<\/ul>\n
Complex Example<\/strong>:<\/p>\nMan @Image1 comes home tired from work, walks down the hallway\r\nslowing his pace, stops at the front door. Close-up of his face\r\nas he takes a deep breath, adjusts his expression from stressed\r\nto relaxed. Close-up of him finding his keys, inserting them into\r\nthe lock. He enters and his daughter and pet dog run to greet him\r\nwith a hug. The interior is warm and cozy, with natural dialogue\r\nthroughout.\r\n<\/code><\/pre>\nResult<\/strong>: Man's face identical across all shots (long, medium, close-up), daughter and dog maintain appearances, interior consistent, emotional arc clear<\/p>\n4. Motion and Camera Replication<\/h3>\nWhat You Can Replicate<\/strong>:<\/p>\nComplex Choreography<\/strong>:<\/p>\n\n- Fighting sequences with multiple moves<\/li>\n

- Action scenes with stunts<\/li>\n
- Athletic performances<\/li>\n
- Coordinated group movements<\/li>\n<\/ul>\n
Camera Techniques<\/strong>:<\/p>\n\n- Dolly shots<\/strong>: Smooth tracking on rails<\/li>\n
- Crane movements<\/strong>: Vertical and sweeping motions<\/li>\n
- Tracking shots<\/strong>: Following subject motion<\/li>\n
- Handheld feel<\/strong>: Documentary-style natural shake<\/li>\n
- Hitchcock zoom<\/strong>: Dolly zoom\/vertigo effect<\/li>\n
- Whip pans<\/strong>: Fast transitions between subjects<\/li>\n
- Orbit shots<\/strong>: 360\u00b0 circular camera movement<\/li>\n<\/ul>\n
Editing Rhythm<\/strong>:<\/p>\n\n- Cut timing between shots<\/li>\n
- Transition styles (hard cuts, fades, wipes)<\/li>\n
- Pacing variations<\/li>\n
- Montage sequences<\/li>\n<\/ul>\n
Advanced Camera Example<\/strong>:<\/p>\nReference @Image1 for the man's appearance in @Image2's elevator\r\nsetting. Fully replicate @Video1's camera movements and the\r\nprotagonist's facial expressions. Hitchcock zoom when startled,\r\nthen several orbit shots inside the elevator. Doors open, tracking\r\nshot following him out. Exterior scene references @Image3, man\r\nlooks around. Reference @Video1's mechanical arm multi-angle\r\nfollowing shots tracking his line of sight.\r\n<\/code><\/pre>\n5.

Complex Template Example<\/strong>:<\/p>\nReplace the person in @Video1 with the girl in @Image1. Replace\r\nthe moon goddess CG with an angel referencing @Image2. When the\r\ngirl crouches, wings grow from her back. Wings sweep past camera\r\nfor transition. Reference @Video1's camera work and transitions.\r\nEnter the next scene through the angel's pupil, aerial shot of\r\nthe angel (spiraling wings match the pupil), camera descends\r\nfollowing the angel's face, pulls back on arm raise to reveal\r\nthe stone angel statues in background. One continuous shot\r\nthroughout.\r\n<\/code><\/pre>\n6. Video Extension (Seamless Continuity)<\/h3>\nCapability<\/strong>: Extend existing videos while maintaining narrative and visual coherence<\/p>\nExample Prompt<\/strong>:<\/p>\nExtend @Video1 by 15 seconds. Reference @Image1 and @Image2 for\r\nthe donkey-on-motorcycle character. Add a wild advertisement\r\nsequence:\r\n\r\nScene 1: Side shot, donkey bursts through fence on motorcycle,\r\nnearby chickens startled.\r\n\r\nScene 2: Donkey performs spinning stunts on sand, tire close-up\r\nthen aerial overhead shot of donkey doing circles, dust rising.\r\n\r\nScene 3: Mountain backdrop, donkey launches off slope, ad copy\r\nappears behind through masking effect (text revealed as donkey\r\npasses): \"Inspire Creativity, Enrich Life\". Final shot: motorcycle\r\npasses, dust cloud rises.\r\n<\/code><\/pre>\nResult<\/strong>: Original video seamlessly continues with new scenes matching style, character, motion quality, and narrative flow<\/p>\nBest Practice<\/strong>: Set generation duration to match extension length (extend by 5s = generate 5s)<\/p>\n7. Video Editing (Non-Destructive Modification)<\/h3>\nCharacter Replacement<\/strong>:<\/p>\n\n- Swap actors while keeping action identical<\/li>\n
- Change protagonists in scenes<\/li>\n

Style Transfer<\/strong>:<\/p>\n\n- Apply new visual treatments<\/li>\n
- Change color grading<\/li>\n
- Modify lighting atmosphere<\/li>\n<\/ul>\n
Narrative Changes<\/strong> (Plot Subversion):<\/p>\nDramatic Example<\/strong>:<\/p>\nSubvert the plot of @Video1. The man's expression shifts instantly\r\nfrom tender to cold and ruthless. In the moment the woman least\r\nexpects it, he shoves her off the bridge into the water. The push\r\nis decisive, premeditated, without hesitation\u2014completely subverting\r\nthe romantic character setup. As she falls, no scream, only\r\ndisbelief in her eyes. She surfaces and shouts at him: \"You were\r\nlying to me from the start!\" He stands on the bridge with a cold\r\nsmile and says quietly: \"This is what your family owes mine.\"\r\n<\/code><\/pre>\nResult<\/strong>: Complete tonal shift from original\u2014romantic scene becomes thriller\/betrayal<\/p>\n8. Audio-Synchronized Generation<\/h3>\nNative Audio Capability<\/strong>: Seedance 2.0 generates videos with built-in sound\u2014not silent outputs requiring post-production<\/p>\nWhat's Generated<\/strong>:<\/p>\nLip-Sync Dialogue<\/strong>:<\/p>\n\n- Multi-language support<\/li>\n
