About Rowbyte Separate RGB
Rowbyte Separate RGB operates on the red, green, and blue channels of a clip inside After Effects and Premiere Pro. It offers per‑channel lens distortion for chromatic aberration and automatically expands clip boundaries as the effect is applied. The plugin can also blur an individual channel and blend each channel with the original footage. Compatibility includes After Effects versions from CS6 through 2024 and Premiere Pro versions from CS6 through the 2020 release, on Windows. Later builds added multi‑frame rendering support in After Effects and Apple Silicon support for Premiere Pro. A demo video is available and the plugin is listed as free, though licensing terms may vary.
