Seedance 2.5 · Coming Soon to Hilight ！
Quick Answer
Seedance 2.5 is coming soon to Hilight. Compared with Seedance 2.0, the new model supports native video generation of up to 30 seconds, increases the reference limit to 50 multimodal assets, and provides stronger control over motion, continuity, and targeted edits.
Once it launches, Seedance 2.5 will be available across five Hilight tools: Text to Video, Image to Video, B-Roll Clips, Virtual Try-On, and Product Close-Ups.
A few seconds may be enough to test a motion or visual idea, but not to develop a complete sequence. As videos get longer, keeping people, products, settings, and camera movement consistent becomes just as important as the quality of an individual frame.
Seedance 2.5 focuses on those practical challenges, giving creators more room to develop an idea and clearer ways to guide motion and refine the result.
What Is Seedance 2.5?
Seedance 2.5 is ByteDance's latest AI video generation model. It brings a longer timeline and multiple forms of creative input into one generation workflow.
Creators can combine text, images, videos, audio, subject references, motion references, style guides, and storyboards. Each asset has a distinct role, such as preserving a product's appearance, establishing the setting, guiding a performance, or arranging the shot order.
Instead of relying on one prompt to do everything, creators can define the subjects, scene changes, camera movement, and audio direction before generation begins.
Seedance 2.5 vs. Seedance 2.0: What Has Changed?
| Capability | Seedance 2.0 | Seedance 2.5 |
|---|---|---|
| Native duration | Better suited to shorter generated clips | Supports native video generation of up to 30 seconds |
| Reference assets | Supports up to 12 reference files | Supports up to 50 multimodal references |
| Motion control | Multimodal guidance and basic motion control | Greater control through reference videos, complex motion, and spatial relationships |
| Long-scene continuity | Consistent output for shorter creative sequences | Stronger continuity across subjects, objects, settings, lighting, and visual style |
| Refinement | Local issues often require another full generation | Specific elements can be changed while preserving the rest of the video as much as possible |
In simple terms, Seedance 2.0 expanded what creators could provide as input. Seedance 2.5 expands how much they can generate, how precisely they can direct it, and how easily they can refine the result.
Six Core Upgrades in Seedance 2.5
Here is how each change affects the creative process.
1. Native 30-Second Narratives
Thirty seconds changes more than the duration of the output. It changes the kind of sequence the model can create. Shorter generations often capture one action, one product reveal, or one visual idea. A 30-second generation creates room for an opening, progression, transition, and ending, with the subject, environment, and camera continuing to develop throughout the sequence.
| A shorter clip typically delivers | A 30-second narrative can develop |
|---|---|
| One action or visual highlight | A sequence with a beginning, progression, and ending |
| A single subject reveal | An evolving relationship between subject, setting, and event |
| A mood or motion test | A complete structure shaped by pacing, camera movement, and emotion |
2. Up to 50 Multimodal References
Seedance 2.5 can work with up to 50 multimodal references in a single generation. Images can establish a person, product, or location. Videos can guide movement and camera behavior. Audio can shape pacing and emotion, while storyboards can define the order of shots.
The goal is not to fill every available reference slot. Each asset should have a clear purpose:
Preserve appearance, color, material, clothing, and identity.
Define the location, lighting, framing, color palette, and overall visual direction.
Guide performance, object interaction, movement paths, and camera rhythm.
Establish music, emotion, voice direction, and storyboard order.
3. Reference Video Control
Text can explain what should happen, but it often struggles to communicate exactly how an action should unfold. A reference video can define movement paths, timing, camera distance, tracking behavior, and the spatial relationship between people and objects.
For hand interactions, character performance, complex camera moves, or scenes involving multiple subjects, a motion reference is often more useful than adding another layer of descriptive adjectives.
4. Stronger Long-Scene Continuity
Longer videos only work when the content remains consistent. A person should not change appearance between shots. A product should not shift shape or color. Lighting, spatial relationships, and camera rhythm should not change without a reason.
Seedance 2.5 places greater emphasis on preserving subject identity, object form, setting, lighting, and visual style as the scene develops. This allows the video to progress as one connected sequence rather than a collection of unrelated moments.
5. Precise Local Editing
When most of a generated video already works, one incorrect detail should not force a complete regeneration. Seedance 2.5 supports targeted changes to objects, backgrounds, people, expressions, clothing, styles, and effects while preserving as much of the original composition, motion, pacing, and camera structure as possible.
| What can be changed | What can be preserved |
|---|---|
| Object color, material, or detail | Subject position, movement, and framing |
| Background or environmental elements | Spatial relationships, lighting, and scene rhythm |
| Person, expression, or clothing | Other subjects, performance, and camera movement |
| Style or visual effects | Core content and overall video structure |
6. Multilingual Creation and Post-Production Flexibility
Seedance 2.5 also extends multilingual creation and provides output that is easier to carry into later text, music, editing, and localization workflows.
Multilingual video involves more than replacing subtitles. Voice, pacing, timing, and visual context all need to work together. Better support for these relationships makes it easier to develop regional versions while preserving the main creative direction.
How Seedance 2.5 Will Work in Hilight
Seedance 2.5 is coming soon as a model option across five Hilight tools.
1. Text to Video
Use Text to Video when you have an idea but no existing footage. Describe the subject, setting, action, and camera direction to create the scene. With up to 30 seconds available, the result can develop beyond one short action and include an entrance, progression, shot changes, and an ending.
2. Image to Video
Use Image to Video when you already have a product image, portrait, or illustration and want to turn it into moving footage. The new model carries the original subject, colors, and visual style through camera movement while introducing more natural action, environmental change, and scene development.
3. B-Roll Clips
Use B-Roll Clips when an existing video needs an opening atmosphere shot, an establishing shot, or a transition.
Describe the missing shot, add a reference image when needed, then select the scene type, visual style, and camera movement. Better scene understanding and shot continuity help the new footage fit more naturally into the existing edit.
4. Virtual Try-On
Upload a clear image of the garment, choose a model from Hilight's library or upload a reference photo, then select a lifestyle setting, minimalist studio look, or street-style fashion treatment.
You can also choose how the garment is presented, such as a natural pose, walking sequence, or turn. As the model moves, the garment's color, silhouette, fabric texture, and print remain more stable.
5. Product Close-Ups
Upload a product image and choose whether to highlight the overall design, material finish, surface texture, or label details.
You can then select a background treatment and camera movement, including static shots, push-ins, tracking shots, orbiting moves, and macro close-ups. Packaging, color, and key product details remain clearer as the camera moves closer to or around the subject.
How to Write a Better Seedance 2.5 Prompt
A useful prompt should do more than list words such as “product,” “model,” “camera movement,” and “advertisement.” It should tell the model what must remain consistent, what happens over time, how each reference should influence the result, and what the finished video needs to achieve.
| Prompt section | What to include |
|---|---|
| Product information | Product type, appearance, color, material, packaging, logo placement, and details that must remain unchanged |
| Video structure | Total duration and what happens during the hook, product reveal, use case, selling-point sequence, and ending |
| Reference direction | The role of each image or video, plus the intended setting, action, camera movement, lighting, and sound |
| Marketing goal | Target audience, publishing channel, primary selling points, brand tone, and intended viewer action |
Complete Prompt Example
Create a 30-second vertical launch video for a reusable insulated tumbler. Keep the cylindrical shape, light-blue matte finish, silver rim, logo placement, and metallic material from the product reference consistent in every shot. Do not change the product proportions or add new text or decoration.
From 0–4 seconds, use a fast push-in toward the tumbler on a tabletop, with condensation and cool mist creating the opening hook. From 4–10 seconds, orbit around the lid, rim, and matte texture to emphasize the seal and finish. From 10–19 seconds, show a female commuter placing the tumbler into a tote bag and drinking from it at an office desk. Keep her movement natural and the product appearance unchanged. From 19–26 seconds, use separate close-ups of steam and ice to demonstrate temperature retention for both hot and cold drinks. From 26–30 seconds, return to a clean product hero shot with the tumbler centered and safe space on the right for the brand logo and call to action.
Use a bright, clean, modern lifestyle advertising style with natural daylight, soft studio lighting, and smooth camera movement. Begin with faster pacing and settle into a calmer ending. Add a polished, upbeat soundtrack with realistic ambient sound. The video is intended for a social media product launch targeting urban commuters aged 25–40. Focus on portability, a secure seal, and all-day temperature retention, then end by inviting viewers to learn more.
If you are unsure how to write a prompt or do not yet have a complete video concept, choose Hilight Smart Video. Add a product link, product assets, and a basic creative brief. Smart Video analyzes the product information, verifies the product and hero image, organizes the available assets, distills the key product information, and identifies relevant high-performing creative references.
It then develops the creative direction, pacing, and storyboard. Once the storyboard is approved, Smart Video can continue generating voiceover, subtitles, and editing assets for a complete marketing video.
If you already know the exact shot you want to create, you will be able to go directly to Text to Video, Image to Video, or another supported Hilight tool and select Seedance 2.5 after launch.
