"We cut video ad production time by 80%. One product photo becomes a full 15-second ad in minutes. Character consistency sold our client — same face, three different markets."

ByteDance's most capable AI video model. Give it a prompt, a reference photo, a video clip, or an audio file — it generates professional-grade video that matches. Characters stay consistent across every shot. Lip-sync is frame-accurate. No GPU. No install.
Lip-Sync from
Any Audio
Upload a voiceover or music track. Mouth movement and body rhythm sync frame-accurately — for speech and beat-driven music.
Consistent
Characters
One reference photo locks in face, outfit, and proportions across every shot — different angles, lighting, and scenes.
Use Any Asset
as a Reference
Combine an image, a video clip, and audio in one generation. Tag each with @Image1 / @Video1 / @Audio1 in your prompt.
Extend &
Bridge Clips
Add 5–15 s to any clip, or connect two separate shots with a seamless generated transition — no visible cut.
Upload images, audio, or video clips — and get cinematic AI video in minutes. Precise lip-sync, consistent characters, seamless clip extension. No install required.

Seedance 2.0 supports text, image, video, and audio as input references. Combine multiple types of materials to guide AI video generation with greater precision and creative control.
Type @ to quickly insert uploaded files into the prompt — e.g. @Image1, @Video1, @Audio1.
Audio cannot be used alone with text — at least one image or video is required.
Each capability maps to a real production problem — built into Seedance 2.0 by ByteDance, not bolted on.
Upload dialogue, music, or narration and Seedance 2.0 generates matching visuals with millisecond-accurate lip-sync. Sound becomes the director — the first AI video generator built this way.
Facial features, attire, and body type stay locked across every angle and environment. Your characters remain themselves from frame one to the last — no drift, no inconsistency.
The model synthesizes synchronized Foley effects — footsteps, rustling fabric — and layers environment-specific ambient sound automatically, producing a full cinematic audio experience.
Lighting, color grading, and spatial logic stay consistent across multiple shots. Design long-form stories with confidence — Seedance 2.0 handles the continuity so you don't have to.
Feed images, video clips, and audio simultaneously as creative references. Product photos, past footage, brand music — whatever assets you already have become the blueprint for generation.
Generate the next 5–15 seconds of an existing clip without re-describing the scene, or connect two clips with a generated bridge. Same characters, same camera logic — no visible cut.

Three steps from idea to cinematic output — choose your input, write your prompt, and generate in minutes. No learning curve required.
An image locks in visual style. A video clip defines motion. An audio file sets rhythm. You can combine all three — or just start with text.
Write what you want, then tag what you uploaded: '@Image1 for character style, follow the movement of @Video1.' That's the full instruction set — no special syntax to learn.

The same model works across different production types. Here's how different teams use it.
Turn a product photo into a video ad without a production shoot. Generate variants for different markets from one reference image — same character, same product, different background or audio. Most teams do 3–4 variants per week this way.
Keep your main character consistent across every episode with one reference photo. Close-ups, wide shots, different lighting — the face stays the same. No need to re-describe the character each time.
Film yourself once, then use that clip as a motion reference for different character styles — anime, cinematic, costume swaps. What used to take all day now takes about an hour.
Generate a shot, extend it 10 seconds, then stitch another shot onto the end. You can show a director a 30-second continuous sequence instead of three disconnected clips. Good for pre-viz before any crew or set is involved.
Record your voiceover, upload a character photo, write a short prompt — the output includes accurate lip-sync. No green screen, no actor scheduling, no post-production audio work.
Feed in an environment sketch and a camera reference clip. Get a 10-second walkthrough video your art director and client can actually review before any 3D work starts.
Swap outfits, replace background elements, or add effects inside an existing clip. One source video, multiple variations. No reshooting required.
Upload a reference choreography clip and apply those exact movements to any character. Useful for dance covers, action sequences, and sports motion replication.
