Overview
What is Seedance 1.5 Pro?
Seedance 1.5 Pro is a ByteDance model available in Starpop. High-quality video generation with native audio and up to 12-second clips. A ByteDance video model for native-audio shots across a particularly broad set of social and cinematic aspect ratios.
Use it when the delivery plan includes uncommon formats such as 4:3, 3:4, or 21:9 as well as standard portrait and landscape. Starpop keeps the model, input mode, duration, format, resolution, and credit choices in one workspace so a team can move from a first test to a publishable asset without rebuilding the brief in another tool.
