Seedance 1.5 Pro / テキストから動画
Supports generating video with audio from text and images, and supports first and last frames.
Seedance 1.5 ProCinema Video with Synchronized Sound
Seedance 1.5 Pro adds native audio synthesis, adaptive duration (-1), and a draft mode for cheap previews — alongside full text / image / frame conditioning at up to 1080p.
Next-Gen Seedance Capabilities
Audio-aware generation with smarter duration selection and draft previews.
Native Audio Co-Synthesis
Turn on native audio to receive time-aligned environmental sound, foley, and ambience locked to on-screen motion.
Adaptive Duration & Draft Mode
Pass seconds: -1 to let the model choose clip length from prompt pacing, or enable draft mode for faster cheaper previews before final 1080p renders.
First & Last Frame Bridges
Animate between two stills for match cuts, product morphs, and scene transitions that land exactly on the end frame.
Camera Lock for Product Work
Freeze the virtual camera so only the subject moves — cleaner packshot motion and fewer accidental reframes.
How It Works
A production-ready path from brief to finished asset.
Describe Scene + Sound Intent
Write the visual beat and, if useful, the acoustic mood (rain, crowd, engine, silence).
Enable or Disable Audio
Leave native audio on for finished clips, or turn it off when you need a silent plate for post.
Use Adaptive or Fixed Length
Pass -1 to let the model pace the clip, or pin 4–12 seconds for strict editorial timing.
Draft → Final
Preview in draft mode, then re-run at full quality for delivery-ready masters.
Audio-First Production
When the soundtrack is part of the generation, not a post pass.
Social with Sound
Native ambience for TikTok / Reels without a separate audio track.
Product Film Previews
draft mode for cheap client previews before final renders.
Narrative Shorts
Adaptive duration lets the model pace dialogue-friendly clips.
Seamless Scene Chains
Chain clips with continuous ambient sound via last-frame continuation.
Prompt & Usage Tips
Practical guidance for reliable first-pass results.
If you want sound, name environmental cues (rain on metal, distant traffic). Silence should be explicit.
For narrative or dialogue-ish clips, adaptive duration often times cuts better than a fixed number.
Validate motion in draft/silent first, then enable audio for the final pass.
Audio-Enabled Quickstart
Generate clips with synchronized native audio in one request.
