Adobe After Effects works in the RGB (red, green, blue) color space. Adobe Premiere Pro, however, works in the YUV color space. When you work with a dynamically linked composition, Adobe Premiere Pro either converts it to YUV or retains the RGB color space, depending on the output format.
Dynamically linked compositions are rendered in the color depth of the After Effects project (8-, 16‑, or 32‑bpc, depending on project settings). Set the After Effects project color depth to 32‑bpc if you’re working with HDR (high dynamic range) assets.
In Adobe Premiere Pro, choose Project >
Project Settings > Video Rendering, and select Maximum
Bit Depth to have Adobe Premiere Pro process at the highest possible
quality. This option may slow processing.
