README

Seedance 1.5 Pro is an asynchronous video generation model on ReachAPI for 4-12 second outputs, adaptive aspect ratios, and token pricing that varies by audio output.

Seedance 1.5 Pro supports text prompts plus first-frame and last-frame image guidance for polished short-form video generation.
It is a strong fit for brand visuals, product motion, character beats, and cinematic clips that benefit from adaptive aspect ratios.
Use this model for Seedance 1.5 workflows that need adaptive aspect ratios and a stronger Pro video generation profile.
