How to Separate RGB in OBS?

[fullmagic]

Hi.
I'm trying to make "Color Shift" effect in OBS like example.

example: https://gyazo.com/4f501408d06af0030f8166b125c6de56

I tried using the color correction filter and the streamFX color grading filter, but it didn't work.

I think, To make "Color Shift" effect on video source, I need to separate RGB channel from video.
But I don't know how to separate RGB.

Thank you for your advices.

I think you can use Shaderfilter.

OBS Shaderfilter

The obs-shaderfilter plugin for OBS Studio is intended to allow users to apply their own shaders to OBS sources. The filter can be added to any source through the "Filters" option when right-clicking on a source. The name of the filter is...

obsproject.com

gamma_correction.shader in the examples would be the best place to start writing a shader to retrieve each channel.
You can just retrieve R channel for example as below.
float4 mainImage(VertData v_in) : TARGET
{
float4 color = image.Sample(textureSampler, v_in.uv);
return float4(color.x, 0, 0, 1);
}
You should put your source to multiple scenes similarly. Then, apply the filter to each scenes with different color channel settings so that each scene has each color channel. Then, you can combine with `Blending mode` = `Additive`, which is available in the next release 27.2.0. Or, you can use my plugin Multi Source Effect.
