What is Doubao Seedance 1.5 Pro?
Doubao Seedance 1.5 Pro is ByteDance’s December 2025 audio-enabled video model. Built to handle both text-to-video and image-to-video creation, it offers native audio support, a wider selection of clip lengths, and more precise frame-guided control than legacy Seedance 1.0 Pro iterations.
What is Seedance 1.5 Pro best for?
Seedance 1.5 Pro excels at short ad concepts, social media clips, character-focused talking-head shots, first-frame guided product videos, and transition clips where you need synchronized motion control and sound generation in a single generation pass.
Which generation modes are available here?
On this platform, Seedance 1.5 Pro supports text-to-video, first-frame image-to-video, and first-and-last-frame transition workflows. The generator interface only includes the generation modes this model is optimized for.
Does Seedance 1.5 Pro support audio generation?
Absolutely. Seedance 1.5 Pro marks the first Seedance model in this lineup with native audio generation built directly into its core workflow. This makes it far better suited to dialogue-focused clips, atmospheric scenes, and sound-aware short videos than earlier Seedance 1.0 variants.
Which durations, aspect ratios, and resolutions does it support here?
Right now, Seedance 1.5 Pro lets you create clips of 4, 5, 8, 10, and 12 seconds in length. It additionally works with 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 outlining your core subject and intended action, then layer in camera movement, scene context, audio goals, and any required frame restrictions. If you’re using first-frame or first-and-last-frame modes, specify which elements need to remain 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?
Opt for Seedance 1.5 Pro when you require native audio support, a wider range of clip lengths, or more precise control over first-and-last-frame transitions. Choose Seedance 1.0 Pro Fast or Quality instead if you want a streamlined 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 use Seedance 1.5 Pro for commercial creative projects on this platform, but all generated videos still require your standard brand, legal, and content reviews. Treat model outputs as raw production material that needs thorough vetting, not as automatically approved footage.
