What is Doubao Seedance 1.5 Pro?
Doubao Seedance 1.5 Pro is ByteDance’s December 2025 audio-native video model. Designed to tackle both text-to-video and image-to-video creative tasks, it comes with built-in native audio support, a broader range of clip durations, and more accurate frame-guided control than older Seedance 1.0 Pro versions.
What is Seedance 1.5 Pro best for?
Seedance 1.5 Pro excels at quick commercial concepts, social media short clips, character-focused talking-head footage, first-frame guided product demos, and transition sequences where synchronized motion control and sound generation happen in a single generation pass.
Which generation modes are available here?
Within this platform, Seedance 1.5 Pro offers text-to-video, first-frame image-to-video, and first-and-last-frame transition workflows. The generator dashboard will only surface the generation modes this model is specifically optimized to run.
Does Seedance 1.5 Pro support audio generation?
Yes, fully. Seedance 1.5 Pro is the first model in this Seedance lineup to have native audio generation integrated directly into its core creation pipeline. This sets it apart from older Seedance 1.0 versions, making it far better suited for dialogue-driven clips, atmospheric scenes, and sound-conscious short videos.
Which durations, aspect ratios, and resolutions does it support here?
Currently, Seedance 1.5 Pro enables you to generate clips ranging from 4, 5, 8, 10, to 12 seconds long. It also supports 16:9, 9:16, 1:1, 4:3, 3:4, and 21:9 aspect ratios, alongside 480p, 720p, and 1080p output resolutions.
How should I prompt Seedance 1.5 Pro?
Start by mapping out your central subject and desired action, then add camera movement, scene context, audio objectives, and any mandatory frame constraints. If you’re using first-frame or first-and-last-frame modes, note which elements must stay consistent before describing any motion or atmospheric tweaks.
When should I use Seedance 1.5 Pro instead of Seedance 1.0 Pro Fast or Quality?
Pick Seedance 1.5 Pro if you need native audio support, a broader selection of clip durations, or more exact control over first-and-last-frame transitions. Opt for Seedance 1.0 Pro Fast or Quality instead if you prefer a streamlined silent video workflow and don’t require the updated audio-native generation features.
Can I use Seedance 1.5 Pro for commercial work?
You may use Seedance 1.5 Pro for commercial creative projects on this platform, but every generated video still needs your standard brand, legal, and content sign-offs. Treat model outputs as raw production assets that require thorough vetting, not pre-approved finished footage.
