What is Doubao Seedance 1.5 Pro?
Doubao Seedance 1.5 Pro is ByteDance’s December 2025 audio-native video model. Built to tackle both text-to-video and image-to-video creative assignments, it comes with native built-in audio support, a broader range of clip lengths, and more accurate frame-guided control than prior Seedance 1.0 Pro builds.
What is Seedance 1.5 Pro best for?
Seedance 1.5 Pro excels at quick commercial pitches, short social media reels, character-focused on-camera footage, first-frame guided product demos, and transition sequences where synchronized motion control and audio generation wrap up in a single generation pass.
Which generation modes are available here?
On 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 show the generation modes this model is specifically optimized for.
Does Seedance 1.5 Pro support audio generation?
Yes, natively. Seedance 1.5 Pro is the first model in this Seedance series to have native audio generation integrated directly into its core production pipeline. This sets it apart from older Seedance 1.0 builds, making it far better suited for dialogue-focused clips, atmospheric scenes, and sound-conscious short videos.
Which durations, aspect ratios, and resolutions does it support here?
Currently, Seedance 1.5 Pro allows you to generate clips ranging from 4, 5, 8, 10, and 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 outlining your core subject and planned action, then add camera movement, scene context, audio targets, and any non-negotiable frame limitations. If you’re using first-frame or first-and-last-frame modes, note which elements need to remain consistent before specifying any motion or atmospheric tweaks.
When should I use Seedance 1.5 Pro instead of Seedance 1.0 Pro Fast or Quality?
Opt for Seedance 1.5 Pro if you need native audio support, a broader range of clip lengths, or more accurate control over first-and-last-frame transitions. Stick with Seedance 1.0 Pro Fast or Quality if you prefer a streamlined silent video pipeline and don’t need the updated audio-native generation tools.
Can I use Seedance 1.5 Pro for commercial work?
You can utilize Seedance 1.5 Pro for commercial creative projects on this platform, but every generated video still requires your standard brand, legal, and content sign-offs. Treat model outputs as raw production assets that need thorough review, not pre-approved final footage.
