Seedance v1.5 Pro

Seedance v1.5 Pro is a video generation model from ByteDance's Seed AI organization, positioned as the pro-tier entry in the Seedance 1.5 family. According to third-party product listings, the broader Seedance 1.5 line is described as being powered by an MMDiT Multimodal Diffusion Transformer architecture, giving it the underlying multimodal diffusion framework that supports both visual and audio generation within a single pipeline. This architecture lets the model handle coherent multi-shot arrangements and natural movement, making it well-suited to creators and brands who need controllable video output rather than simple single-clip renders.

In practical terms, Seedance v1.5 Pro is positioned for narrative-driven video work, with third-party directories describing it as a "Narrative with cohesive shots pro version" that produces clips of roughly 5 to 12 seconds at 480p to 720p resolution, with end-frame control alongside audio output. The 1.5 generation is credited with native synchronization of video and audio and intelligent trajectory extraction from static inputs, so motion and sound track together without a separate audio pass. That combination makes the variant a practical fit for UGC ads, product visuals, and social content where short, story-led clips with built-in audio are the deliverable.
