YouTube Adds New Shorts Options, Landscape View for Studio Mobile
Briefly

Up until now creators could only remix single elements for Shorts, for example a song, video, or effect. But now, creators can replicate or build on attributes from any existing video they've watched, including inherited elements like audio segment timing and text.
The goal is to spark inspiration, support trends, and participate in the community, and we'll be bringing this to all creators in the coming weeks.
We expect viewers who use this option aren't users who would frequently watch Shorts to begin with, so we don't anticipate a material impact to creators.
