Seedance now supports 16:9 → 9:16 aspect ratio conversion via single prompt. This means you can batch-convert landscape videos into vertical format for IG Reels, YouTube Shorts, and TikTok without manual cropping or editing.
The real value: automated content repurposing pipeline. Instead of shooting twice or using third-party editors, you feed horizontal footage and get platform-optimized verticals out.
This is huge for creators with existing horizontal libraries — suddenly all that content becomes reusable across short-form platforms. The prompt-based approach suggests the model intelligently reframes (likely tracking subjects and recomposing shots) rather than just center-cropping.
If you've been sitting on a backlog of 16:9 content, this unlocks instant multi-platform distribution.
