What Seedance Can Film
Representative frame previews of the styles and scenes Seedance excels at β these stills illustrate the look, not actual video output from the model.
What Makes Seedance Stand Out
Three capabilities that set Seedance apart from other video models.
Fluid, natural human motion and dance
Seedance excels at the human body in motion β leaps, spins, and dance moves flow naturally, with limbs staying stable at full speed.
Multi-shot narrative sequences in one clip
A single generation can chain several shots together, cutting between angles and moments like a real edit to tell a small story.
Fast generation for cheap, rapid iteration
Quick renders and a low per-clip cost let you retry motion and framing until the shot lands.
What is Seedance 1.5 Pro?
Seedance 1.5 Pro is ByteDance's joint audio-video generation model. Unlike most video AIs that output silent footage you have to score afterward, Seedance generates the picture and the soundtrack at the same time, so dialogue, ambient sound, and on-screen action are aligned from the first frame. Its standout feature is multilingual lip-sync: characters can speak across languages with mouth movements that track the audio convincingly.
The model renders at 480p or 720p and produces clips from 1 to 8 seconds long. It is flexible on framing, supporting a wide range of aspect ratios including 16:9 and 9:16 for landscape and vertical, 4:3 and 3:4, the cinematic 21:9 ultrawide, and 1:1 square. That makes it equally at home producing a YouTube intro, a TikTok short, or a square social ad without cropping or letterboxing.
Seedance works in both text-to-video and image-to-video modes. You can animate from a single still, or supply both a first and last frame (two images) to guide the motion between a defined start and end pose. Every generation costs a flat 20 credits, which keeps experimentation cheap when you are dialing in a prompt or a lip-synced line of dialogue.

Why Choose Seedance
What makes Seedance 1.5 Pro different from a generic video generator.
Audio + video in one pass
Seedance generates the soundtrack alongside the footage, so action and sound are synced from the start. No separate scoring or dubbing step required.
Multilingual lip-sync
Characters can speak across languages with mouth movements that genuinely track the audio. Ideal for talking-head clips and localized content.
First + last frame control
Supply two images, a starting and ending frame, and Seedance interpolates the motion between them for precise, repeatable shots.
Every aspect ratio you need
From 21:9 cinematic ultrawide to 9:16 vertical and 1:1 square, generate native to the platform instead of cropping a 16:9 clip.
Text and image to video
Start from a written prompt or animate an existing still image. Two input modes cover both blank-page ideation and asset reuse.
Just 20 credits a clip
A flat, low cost per generation makes it cheap to iterate on prompts, dialogue, and framing until the shot is right.
