How to Add Channel Blur Effect on Premiere Pro [MEW]
The Channel Blur effect in Adobe Premiere Pro, which allows you to blur the red, green, blue, or alpha channels independently to create artistic color-fringing effects like halation, can be found by navigating to the Effects panel (Window Effects), then searching for "Channel Blur" under the Blur & Sharpen or Channel categories, and dragging it onto your desired clip in the timeline. You then adjust the individual color channel blurriness sliders in the Effect Controls panel (Window Effect Controls). However, because Channel Blur is an older, often non-GPU accelerated effect, which can significantly slow down modern Premiere Pro versions, you may consider an alternative workflow like duplicating your video layer three times, setting the blending mode of the top two layers to Linear Dodge (Add), isolating the color in each layer using the Lumetri Color panel's Curves or a similar color effect, and then applying the GPU-accelerated Gaussian Blur to each individual color channel layer to replicate the effect with better performance.
