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 jobs, it comes with native built-in audio support, a broader range of clip lengths, and more accurate frame-guided control compared to 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 audio generation wrap up in a single generation pass.
Which generation modes are available here?
For 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 to run.
Does Seedance 1.5 Pro support audio generation?
Yes, natively. Seedance 1.5 Pro is the first model in this Seedance series with native audio generation integrated directly into its core production pipeline. This sets it apart from earlier Seedance 1.0 versions, 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 make clips ranging from 4, 5, 8, 10, up 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 planned action, then add camera movement, scene context, audio objectives, and any non-negotiable frame limitations. If you’re using first-frame or first-and-last-frame modes, note down which elements need to stay consistent before outlining 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 require native audio support, a broader selection of clip lengths, or more accurate control over first-and-last-frame transitions. Stick with Seedance 1.0 Pro Fast or Quality instead if you want a simplified silent video workflow 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 each generated video still requires your standard brand, legal, and content sign-offs. View model outputs as raw production assets that need thorough review, rather than pre-approved final footage.
