What is Doubao Seedance 1.5 Pro?
Doubao Seedance 1.5 Pro is ByteDance’s December 2025 audio-native video model. Designed to handle both text-to-video and image-to-video creative tasks, it includes native built-in audio support, a wider selection of clip lengths, and more precise frame-guided control than earlier Seedance 1.0 Pro iterations.
What is Seedance 1.5 Pro best for?
Seedance 1.5 Pro shines for fast commercial pitches, social media short reels, character-driven on-camera footage, first-frame guided product demos, and transition sequences where synced motion control and audio generation complete in one single generation run.
Which generation modes are available here?
On this platform, Seedance 1.5 Pro provides text-to-video, first-frame image-to-video, and first-and-last-frame transition workflows. The generator dashboard will only display the generation modes this model is specifically tuned to support.
Does Seedance 1.5 Pro support audio generation?
Absolutely, natively. Seedance 1.5 Pro is the first model in this Seedance lineup with native audio generation built directly into its core production workflow. This differentiates it from older Seedance 1.0 builds, making it far better suited for dialogue-focused clips, atmospheric scenes, and sound-aware short videos.
Which durations, aspect ratios, and resolutions does it support here?
Right now, Seedance 1.5 Pro lets you create clips between 4, 5, 8, 10, and 12 seconds in length. 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?
Begin by mapping your core subject and intended action, then add camera movement, scene context, audio goals, and any non-negotiable frame constraints. If you’re using first-frame or first-and-last-frame modes, jot down which elements must stay consistent before detailing any motion or atmospheric adjustments.
When should I use Seedance 1.5 Pro instead of Seedance 1.0 Pro Fast or Quality?
Choose Seedance 1.5 Pro if you need native audio support, a wider range of clip lengths, or more precise control over first-and-last-frame transitions. Stick to Seedance 1.0 Pro Fast or Quality if you prefer 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 can 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 careful review, not pre-vetted final footage.
