Creating a screen flash shader

[sNk]

Hey,

i want to create a screen flash shader like in GTA V (https://youtu.be/vWsJbzT75S0?t=63), but since i dont have any kind of experience in shader languages, i would like to ask, how i would do that with an hlsl shader?

greetings.

I do not understand the video very much, do you want it when it's a kind of screen, is it clear?

I guess this video will show it a little bit better.

I want to create a shader that flashes the screen in a blue tone like in these videos.
