How to disable post process animation so that it takes effect when playing the game?

This is what I mean: https://i.imgur.com/Rotfcjy.mp4

In the video you can see when post process is enabled the animation looks all strange, however when it is disabled, it looks normal. Is there a way to keep it disabled by default? Or at least toggle it for each individual animation?

Thanks,
