What is Doubao Seedance 1.5 Pro?
Doubao Seedance 1.5 Pro is ByteDance’s December 2025 audio-native video model. Generate from a prompt or an image, with native audio, longer clips, and tighter frame 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, first-frame guided product demos, and transition sequences where synced motion control and audio generation wrap up in a single generation pass.
Which generation modes are available here?
Leave the upload empty to generate from your prompt. Add one image for a first frame, or two images when the start and end are fixed. The form only shows inputs this model supports.
Does Seedance 1.5 Pro support audio generation?
Yes, natively. Seedance 1.5 Pro is the first model in this Seedance line 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, moody 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, plus 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 goals, and any non-negotiable frame limitations. If you’re using first-frame or first-and-last-frame modes, jot down which elements need to stay consistent before going over any motion or mood-based adjustments.
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 exact control over first-and-last-frame transitions. Stick with Seedance 1.0 Pro Fast or Quality if you want a streamlined 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 on kling4pro.com, but every generated video still needs your standard brand, legal, and content sign-offs. View model outputs as raw production assets that require careful review, not pre-approved final footage.
