Seedance 3.0 AI is a video generation tool that creates 1080p video with built-in dialogue, music, and sound effects from text, images, video clips, or audio tracks.
What is Seedance 3.0 AI?
Seedance 3.0 AI is a cloud-based video generator that renders 1080p MP4 video with synchronized audio — including lip-synced dialogue, ambient sound, and background music — from a single prompt or a combination of inputs. It accepts text descriptions, uploaded photos, video clips, and music tracks, and outputs a fully edited video clip. The platform is developed by Seedance and requires no local hardware; all processing happens server-side.
Key Features
- Multi-reference input — Combine up to 15 reference images or clips in one prompt to control character appearance, lighting, and motion style.
- Built-in audio — Dialogue, ambient effects, and background music are generated together with the video; no post-production audio editing needed.
- Lip sync in 10+ languages — Written dialogue in English, Japanese, Korean, Mandarin, Spanish, and other languages produces matching mouth movements without dubbing.
- Beat sync — Upload a music track and Seedance 3.0 AI times every transition, zoom, and scene change to the rhythm automatically.
- Video extension — Extend any clip by adding seconds; motion, lighting, and physics continue naturally with no visible seam.
- Prompt-based video editing — Type a change (e.g., "swap the background from a boardroom to a rooftop") and the scene rebuilds around that edit.
- First & last frame control — Pin the opening and ending frames of a clip (e.g., a logo on the first frame, a product shot on the last) and the motion between is entirely generated.
- Multiple AI models — Access models including Seedance 2.0, Seedance 1.5 Pro, Sora 2, VEO 3.1, Kling V3, Kling O3, Vidu Q3, and image models like Nano Banana Pro, Seedream 4.5, Seedream 4.0.
Who is it for?
- Content creators — Generate short-form videos with consistent characters, custom audio, and beat-synced edits for social media or ad campaigns.
- Agencies and studios — Produce high-volume video assets (up to 5,000 credits/month on Enterprise) with commercial-use license and dedicated support.
- Marketing teams — Turn product photos into animated clips, extend existing footage, or edit video scenes by prompt for rapid iteration.
What can you do with Seedance 3.0 AI?
- Create a full video from a text description: Write a scene with camera angles, lighting, and action (e.g., "A chef tosses pasta in a copper pan, steam catching the afternoon light through a kitchen window") and receive a rendered 1080p clip with matching audio.
- Animate a single image: Upload a product shot, portrait, or illustration and have Seedance 3.0 generate motion (e.g., awnings flutter, pedestrians cross) while preserving the original details.
- Match a reference style: Supply a fashion editorial photo as a reference; the tool replicates its lighting, framing, and motion in a new generated video.
- Extend existing clips: Take a 5-second drone shot and stretch it to 15 seconds with continuous wave motion and physics.
- Edit a video's background or elements by typing: Change the setting from a boardroom to a rooftop terrace without re-recording or timeline editing.
How does Seedance 3.0 AI work?
- Drop in your inputs — Write a text prompt, upload character photos, a reference video, or a beat track. A single sentence also works.
- Seedance 3.0 AI renders everything — Video, dialogue, effects, and music are generated together. Lip sync matches your chosen language. Clips arrive in seconds.
- Download or extend — Get a 1080p MP4. Use Video Extension to chain clips longer, or Video Editing to reshape the output with a new prompt.
