What Seedance V1.5 Pro is good at — and what it's not

Seedance V1.5 Pro is the V1-tier text-to-video model with native audio. It carries the Seedance line's strong motion — natural movement and physics — at up to 1080p, and adds a soundtrack generated together with the video, on by default. That's the headline difference from V1.0 Pro: scene sound arrives with the motion, so prompt-driven shots don't need a separate audio pass.

Generations run 4 to 12 seconds across six aspect ratios from 21:9 to 9:16, with the fixed-camera option for static framing. The strong-motion quality makes it a fit for action, dynamic camera moves, and cinematic beats — now with sound.

Where it sits: Seedance V2.0 is the current flagship with top-tier motion and audio; V2.0 Fast is the faster V2 tier with multi-input support; V1.0 Pro is the same V1 tier without audio. For a different look, Kling V3 is the general flagship and Veo 3.1 leads on cinematic photoreal. V1.5 Pro's sweet spot is V1-tier text-to-video with audio.

A reasonable mental model: default to Seedance V1.5 Pro when you want Seedance motion with sound at the V1 tier, and step up to V2.0 for the best motion or down to V1.0 Pro if you don't need audio.
