This video explains a new 3D layers workflow in upcoming versions of After Effects. Orbit, Pan, and Dolly are now right in the toolbar. There’s also a new option to “Create Camera from 3D View”.
This beta came with the AE 17.1.4 (September 2020) release. If you’re an Adobe Creative Cloud subscriber, you can work with beta versions of After Effects and other software.
