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 than older 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, opening-frame guided product demos, and transition sequences where synced motion control and audio generation wrap up in a single generation cycle.
Which generation modes are available here?
Within this tool, Seedance 1.5 Pro offers text-to-video, opening-frame image-to-video, and first-and-last-frame transition workflows. The generator dashboard will only show the generation modes this model is specifically calibrated to support.
Does Seedance 1.5 Pro support audio generation?
Absolutely—natively. Seedance 1.5 Pro is the first model in this Seedance lineup to include native audio generation built straight into its core production workflow. 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 intended action, then add camera movement, scene context, audio objectives, and any non-negotiable frame limits. If you’re using opening-frame or first-and-last-frame modes, note which elements need to stay consistent before going over 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 want a simplified silent video workflow and don’t require the updated audio-native generation tools.
Can I use Seedance 1.5 Pro for commercial work?
You may use Seedance 1.5 Pro for commercial creative projects within this tool, but every generated video still requires your standard brand, legal, and content sign-offs. Treat model outputs as raw production assets that need careful review, not pre-approved final footage.
