What is Seedance 2.0
Seedance 2.0 is ByteDance's flagship video model, released in spring 2026. It is the next generation after the Seedance 1.0 line, which topped independent video generation rankings back in 2025. Version 2.0 takes the senior seat in the family: it delivers the best quality and is the only model in the 2.0 line that generates at 1080p.
The main architectural difference of the 2.0 generation is joint audio and video generation. Earlier video models produced a silent clip and the sound had to be added separately. Seedance 2.0 creates picture and audio in one generation: character lines, sound effects and background music, with lip movement synced in several languages. That makes the model self-sufficient for short scenes with speech.
The second difference is multimodal references. In a single generation the model accepts up to 9 images, 3 video clips and 3 audio files, and refers to them directly in the prompt. Because of that Seedance 2.0 holds a character, object and style, and with a reference video it replicates camera motion and the way things move in frame. Editing and extension modes for a finished clip are available as well.
On Genosai the model runs online: you do not need a developer account, API keys or your own infrastructure. You open the video studio in the browser, describe the scene, optionally upload frames and references, and get a finished clip with sound. Seedance 2.0 suits anyone who needs maximum quality: ad inserts, short scenes with dialogue, product presentations and social content in vertical and horizontal formats.
Capabilities
Seedance 2.0 covers the full cycle of a short clip — from a frame or text to video with sound. Here is what the model does in practice.
Resolution and duration
The model generates at 480p, 720p and 1080p, with 1080p available only in the flagship version of the 2.0 line. Clip length is 4 to 15 seconds at 24 frames per second. The smart-duration mode picks the length by the meaning of the prompt, but you can set it explicitly. Different aspect ratios — 16:9, 9:16, 1:1, 4:3, 3:4 and 21:9 — let you assemble a clip straight for YouTube, Reels, Shorts or a wide frame.
Audio together with video
The key feature of the 2.0 generation is native audio. The model generates an audio track at the same time as the image: dialogue, sound effects and music. Speech is synced to lip movement in several languages, so a short talking scene can be produced whole in one generation, with no separate voiceover and editing.
First and last frame
Seedance 2.0 supports start- and end-frame control. You upload a start image and, if needed, an end one — the model builds smooth motion between them. This is handy for controlled transitions, logo animation, a product turnaround or a storyboard where how the scene begins and ends matters.
References and motion transfer
In a single generation the model accepts up to 9 images, 3 videos and 3 audio files. Images hold a character, object and style from frame to frame; audio sets a voice or a music bed; and a reference video lets it replicate camera motion and how objects move. That turns Seedance 2.0 into a tool not only for generating from scratch but for precisely reproducing the motion you want.
Text and image input
The model works as both text-to-video and image-to-video. In the first case you describe the scene in words; in the second you animate an uploaded frame by giving it motion. Editing and extension of an already finished clip are also available if you need to adjust a scene or add length to it.
Examples
There is no demo gallery for Seedance 2.0 on Genosai yet, so instead of ready clips we describe the typical scenarios the model is built for. The first scenario is text-to-video: you describe the scene in words, and the model generates video with sound, including lines and effects. Specificity about camera motion, light and on-screen action pays off especially well here.
The second scenario is image-to-video: you upload a single frame and give it motion to animate a product shot, a character or a location. The third scenario is first and last frame: you fix the start and end of a scene, and the model builds a smooth transition between them, which is handy for logo animation or a product turnaround. The fourth scenario is working with references: up to 9 images, 3 videos and 3 audio files hold the character, style and camera motion so a series of clips looks like one piece. In all cases the model generates picture and sound together, at up to 1080p.
How to use on Genosai
Launching Seedance 2.0 on Genosai requires no setup: everything happens in the browser and the model is already connected. The basic path from an idea to a finished clip looks like this.
- Sign in to your Genosai account and open the video studio.
- Pick Seedance 2.0 in the model list.
- Describe the scene: action, camera motion, light and sound if you need it.
- If needed, upload a first and last frame and references — up to 9 images, 3 videos and 3 audio files.
- Set the resolution, duration and aspect ratio, then run the generation.
- Download the clip or refine the prompt and regenerate.

These templates show how to phrase tasks for Seedance 2.0. Replace the text in square brackets with your own data and add details on motion, light and sound — the model takes them into account when generating, so specificity pays off.
Text-to-video: [scene and action], smooth camera move [dolly/zoom], natural light, background music, 1080p, 10 seconds.Image-to-video: animate the uploaded frame [description], subtle object and camera motion, keep the composition, 720p.First and last frame: transition from [start frame] to [end frame], smooth motion interpolation, no hard cuts.Dialogue scene: [character] delivers the line [text], lip sync, lively expression, quiet ambient in the background.Product ad: [product] on [background], slow turnaround, studio light, highlights on the surface, a soft click sound.Reference video: replicate the camera move from [reference] but with a new scene [description], same rhythm and dynamics.Vertical 9:16 clip for social: [story], dynamic in-frame editing, energetic music, 15 seconds.Generation cost
On Genosai the cost of Seedance 2.0 depends on resolution and duration and is counted per second of the clip: about 9 credits per second at 480p, 30 credits at 720p and 80 credits at 1080p. So a ten-second clip at 720p costs about 300 credits, while the same clip at 480p is noticeably cheaper. You pay for actual generations, with no monthly subscription, so the spend is easy to plan for a task.
This grid lets you balance the budget flexibly: run drafts and storyboards at 480p, and render the final scene with sound at 1080p. Starter credits after sign-up let you try Seedance 2.0 for free. Current packages and balance are in the Pricing section.
Comparison
Seedance 2.0 is the choice when you need maximum quality, 1080p resolution and audio in a single generation. If speed and price matter more, look at the fast versions of the same line: Seedance 2.0 Fast and the most budget Seedance 2 Mini. Among other families, close in class are Kling 3.0 and Veo 3.1 Quality.
| Model | Strength | Price on Genosai |
|---|---|---|
| Seedance 2.0 | 1080p, audio, references | from 9 credits/sec |
| Seedance 2.0 Fast | Speed, audio, up to 720p | from 15.5 credits/sec |
| Seedance 2 Mini | Lowest price in the 2.0 line | from 9.5 credits/sec |
| Kling 3.0 | Quality and modes with sound | from 14 credits/sec |
| Veo 3.1 Quality | Top detail and 4K | from 250 credits |
All models are available in one Genosai interface, so you can compare them on your own scene and pick the best by price and quality. A practical approach is to run drafts on a fast version and render the final with sound on Seedance 2.0.
Limitations and tips
Seedance 2.0 is the flagship, and that shows in the price: 1080p with sound costs noticeably more than the fast versions. If 1080p and native audio are not critical for you, for volume and drafts it is more rational to take Seedance 2.0 Fast or Seedance 2 Mini and keep the flagship for final scenes. Exact limits and the set of parameters may depend on the studio, so rely on the actual result.
Like any video model, Seedance 2.0 is sensitive to prompt detail. Describe not only the object but the camera motion, light, action and sound: the more specific the input, the more predictable the clip. For talking scenes, state the line itself and keep it sensibly short to fit the duration. For controlled transitions use the first and last frame, and for a single series use shared references.
Work iteratively: get a short draft at 480p, check the composition and motion, then raise the resolution to 720p or 1080p for the final. That way you save credits and reach the result faster, without overpaying for failed takes at maximum quality.
