Plan 30-second stories, coordinate multimodal references, interpret cinematic direction, and refine professional creative ideas with ByteDance's next-generation audio-video model.
Coming Soon
Seedance 2.5 has been released by ByteDance. Nanobana integration is in progress, so generation is not available on this page yet.
Four capabilities that move video generation from a short clip toward a complete creative sequence.
30-second storytelling
Build a complete 30-second segment, then extend it twice when the story needs more room.
Up to 50 references
Coordinate combined image, video, and audio materials inside one richer creative brief.
Cinematic interpretation
Use a reference for framing, camera rhythm, and intent instead of relying on simple motion transfer.
Professional editing
Work toward white-model control, green-screen replacement, blocking, and broader audio-video changes.
Key Features
The four Seedance 2.5 capabilities that matter most.
These four points summarize the model's published capabilities. They describe Seedance 2.5 itself, not controls currently exposed by Nanobana.
Feature 01 · 30-second narrative
Give a complete story beat room to unfold.
Seedance 2.5 can create a single video segment up to 30 seconds and extend it twice. That gives setup, action, camera movement, and resolution more space before separate clips need to be assembled.
Generate one segment up to 30 seconds
Extend the result twice when the sequence needs more time
Plan a beginning, development, and ending in one brief
Feature 02 · Multimodal references
Direct one scene with a richer set of creative evidence.
Up to 50 combined image, video, and audio references can provide appearance, location, movement, sound, and style cues. Clear roles help the model interpret them as one coordinated direction.
Combine image, video, and audio materials
Assign references to characters, products, locations, motion, or sound
Keep complex briefs organized around one intended result
Feature 03 · Reference interpretation
Borrow the filmmaking logic, not just the movement.
Seedance 2.5 is designed to read a reference video's intention, framing, and cinematic language. A creator can direct pacing and camera behavior while changing the subject and story.
Reference framing, shot rhythm, and camera movement
Reinterpret creative intent in a new scene
Move beyond literal motion transfer
Feature 04 · Production control
Shape difficult shots with more deliberate editing tools.
White-model control, green-screen editing, camera direction, performance blocking, and a wider range of audio-video edits make the model more relevant to planned production workflows.
Use white-model input to guide staging and camera structure
Replace green-screen environments while preserving the performance
Respond to a broader range of visual and audio edit requests
Prompt recipes
Draft a complete Seedance 2.5 brief before generation opens.
The fictional Last Tram project turns the four core capabilities into practical prompt structures. Save or adapt them now, then use them when Seedance 2.5 becomes available on Nanobana.
Tell one story in 30 seconds
A clear opening, development, and resolution gives the model enough direction to pace one continuous sequence.
View the prompt+
Create a continuous 30-second cinematic short at blue hour in a rain-washed coastal city. A cobalt-blue vintage tram arrives for its final route. Begin with a wide view through sea mist, track alongside the tram as it slows, move inside to an amber-coated conductor checking a silver case, then end as the tram disappears around the cliff road. Keep the tram design, wet stone streets, teal-and-amber grade, realistic motion, and quiet reflective mood consistent. Include natural tram sounds, rain, distant waves, and no on-screen text.
Give each reference a job so several creative inputs support one coherent scene instead of competing.
View the prompt+
Use @Image1 for the exact cobalt tram design, @Image2 for the conductor's amber coat and face, @Image3 for the silver case, @Video1 for the restrained walking rhythm, and @Audio1 for the bell and wet-track ambience. Create three connected shots at the same coastal station. Preserve character identity, tram proportions, case details, weather, lighting direction, and color grade across every shot. Interpret the references as one cinematic world rather than arranging them as a collage.
A reference supplies pacing and framing while the subject, location, and story remain original.
View the prompt+
Use @Video1 only as a reference for camera language: begin with a slow push through foreground reflections, transition into a lateral tracking move, then finish on a held close-up. Reinterpret that rhythm inside a vintage coastal tram at night. Follow the conductor from the rear door to a passenger holding a silver case. Do not copy the reference subjects or location. Keep movement deliberate, eyelines natural, reflections physically plausible, and the cobalt, teal, and amber palette consistent.
Define what must be replaced and what must remain untouched during a focused production edit.
View the prompt+
Use @Video1 as the green-screen source. Keep the conductor, amber coat, silver case, body movement, timing, and camera angle unchanged. Replace only the green background with a rain-washed coastal tram platform at blue hour, including the same cobalt tram, wet stone reflections, sea mist, overhead practical lights, and distant waves. Match edge light, contact shadows, perspective, depth of field, and ambient sound so the composite feels like one photographed scene. Add no text or logos.
Prepare a Seedance 2.5 video brief in three steps.
The exact Nanobana controls will be finalized with the API integration. These steps focus on the creative decisions already supported by the model's published capabilities.
01
Plan the sequence
Describe the story beat, subject, environment, movement, camera language, sound, and how the 30-second segment should end.
02
Assign the references
Choose only the image, video, and audio materials that clarify identity, setting, motion, sound, or visual direction, and state each role.
03
Generate, extend, and refine
After integration launches, review the first segment, extend only when the story needs it, then make focused edits without changing the whole direction.
Seedance 2.5 questions
What is Seedance 2.5?+
Seedance 2.5 is a next-generation audio-video joint generation model developed by ByteDance. It is designed around 30-second storytelling, multimodal reference control, and more capable video editing.
What is the relationship between Nanobana, Seedance 2.5, and ByteDance?+
Seedance 2.5 is developed by ByteDance. Nanobana is an independent creative platform preparing a web workflow for the model. Nanobana does not develop or own Seedance 2.5 and is not affiliated with or endorsed by ByteDance.
Can I generate with Seedance 2.5 on Nanobana now?+
Not yet. Seedance 2.5 has been released, and Nanobana integration is coming soon. This page currently provides verified capability guidance and prompt planning without submitting generation tasks to another model.
How long can a Seedance 2.5 video be?+
The published model page describes a single generation of up to 30 seconds with the option to extend the video twice. Exact duration choices exposed by Nanobana will be confirmed when the API integration is complete.
How many references can Seedance 2.5 use?+
Public model information describes up to 50 combined image, video, and audio inputs. Nanobana's final upload limits and accepted file requirements will be published with the integration.
What does cinematic reference interpretation mean?+
A reference video can guide framing, camera rhythm, motion, and creative intent rather than acting only as a motion template. The prompt should still state which parts to interpret and which subjects or locations must be different.
Which professional editing tasks does Seedance 2.5 support?+
ByteDance highlights white-model control, green-screen editing, professional camera movement, performance blocking, and broader audio-video editing requests. Nanobana will list the exact exposed controls after integration testing.
Will Nanobana offer 4K Seedance 2.5 output?+
That is not confirmed yet. ByteDance's Seedance 2.5 page does not specify 4K output. Nanobana will publish verified resolution choices when its Seedance 2.5 integration is ready.
Plan the first story you want to make with Seedance 2.5.
Use the prompt recipes to shape a 30-second sequence, choose purposeful references, and define the camera and edits before Nanobana generation opens.
