Seedance 1.5 Pro is ByteDance's cinema-quality video generator with native synchronized audio — producing perfectly lip-synced dialogue, sound effects, and background music in a single pass. Generate 4-12 second videos at up to 1080p with cinematic camera control and character consistency across shots.

What you can create

• Cinematic short films with synchronized dialogue

  Generate cinema-quality scenes with characters speaking naturally in 8+ languages. Seedance 1.5 Pro creates perfectly lip-synced dialogue with matching voice, enabling short narrative sequences, dramatic scenes, and character-driven storytelling with professional audio quality.

• Professional ads and product showcases

  Produce polished promotional videos with ambient sound, music, and voiceover built in. Cinematic camera movements — pan, tilt, zoom, dolly, orbit, and truck — add professional production value to product demos, brand videos, and marketing content.

• Multi-shot narratives with consistent characters

  Create coherent multi-shot sequences where characters maintain their facial features, clothing, and style across different camera angles and scenes. Build short stories, explainer sequences, and serialized content with visual continuity.

• Image-to-video animations with start and end frame control

  Upload a start frame and optional end frame to precisely control how your video begins and concludes. Animate still images into cinematic sequences with natural motion, camera movement, and synchronized audio — perfect for animating artwork, product images, and concept illustrations.

Why creators choose Seedance 1.5 Pro

• Native audio-video generation in one pass

  Audio and video are generated simultaneously using a dual-branch diffusion transformer — not added separately as a post-process. This produces naturally synchronized dialogue, sound effects, and background music that match the visual content from the start, eliminating audio-video alignment issues.

• Multilingual lip-syncing across 8+ languages

  Precise lip-syncing works across English, Mandarin, Japanese, Korean, Spanish, and more. Characters speak naturally in each language with accurate mouth movements, enabling multilingual content creation and localization without re-rendering.

• Cinematic camera control

  Direct your video's cinematography with specific camera movements — pan, tilt, zoom, dolly, orbit, and truck. Describe your desired camera work in the prompt and Seedance 1.5 Pro translates it into smooth, professional camera motion that elevates production quality.

• Up to 1080p resolution with flexible duration

  Generate videos at 480p, 720p, or 1080p resolution with durations from 4 to 12 seconds. Choose the resolution and duration that matches your project requirements — from quick social clips to detailed cinematic sequences.

How to generate your first video

1. Write your prompt or provide an image. Describe your scene with specific details about action, dialogue (in double quotes), camera movements, mood, and desired audio. For image-to-video, upload a start frame and optionally an end frame to control the animation arc.
2. Configure your settings. Choose resolution (480p, 720p, or 1080p), aspect ratio from 7 options (including adaptive), duration (4-12 seconds), and toggle audio on or off. Audio is enabled by default — disable it to reduce credit cost.

Common questions

What is Seedance 1.5 Pro?

Seedance 1.5 Pro is ByteDance's latest video generation model, available via the Replicate API. It uses a dual-branch diffusion transformer architecture to generate audio and video simultaneously — producing cinema-quality videos with perfectly synchronized sound, dialogue, and music in a single pass at resolutions up to 1080p.

How does Seedance 1.5 Pro compare to Seedance 1 Pro?

Seedance 1.5 Pro adds native audio-video generation — audio and video are created simultaneously, not separately. This enables precise lip-syncing, synchronized sound effects, and background music. It also supports multilingual lip-syncing across 8+ languages and both start and end frame control for image-to-video generation.

Does Seedance 1.5 Pro support audio generation?

Yes — audio generation is enabled by default. Seedance 1.5 Pro generates synchronized dialogue, sound effects, and background music that match the video content. You can disable audio to reduce credit cost. For best audio results, describe desired sounds and dialogue in your prompt using double quotes for speech.

What aspect ratios does Seedance 1.5 Pro support?

Seedance 1.5 Pro supports 7 aspect ratios: 1:1, 4:3, 3:4, 16:9, 9:16, 21:9, and adaptive (auto-detected from input image). The adaptive option is useful for image-to-video when you want the output to match your source image dimensions.

How much does Seedance 1.5 Pro cost in credits?

Credit cost depends on resolution, audio, and duration. At 720p without audio, it costs 10 credits per second (50 for 5s). With audio enabled, the rate doubles: 720p with audio costs 20 credits per second (100 for 5s). At 1080p with audio, it costs 50 credits per second (250 for 5s). Disabling audio halves the cost at every resolution tier.

Does Seedance 1.5 Pro support ending frame images?

Yes — for image-to-video generation, you can upload both a start frame and an optional ending frame image. The model animates between the two frames, giving you precise control over where the video begins and ends. This is useful for transitions, product reveals, and controlled animation arcs.
