[Tutorial] Old Move Shader Graph (Plus how-to full screen shaders in URP)

This video started as a "How to set up Full Screen Shaders in URP" (or custom post processing). But while working on the demo shader, I decided that's actually the more interesting part of the video. So the video is a bit more focused on the old timey movie effect.

Which ever part may be more interesting to you, they are both there.

 

Thank you for the tutorial. I was trying to implement the "Blit" code, however, when I do I get the error in the console:
"You can only call camera color target inside the scope of a ScriptableRenderPass"
This is with URP 13.1.7

Do you or anyone else have any theories on how I could update the script to avoid this error? Thanks,
