Pixelated post process material?

I have made a pixelated post process material and it looks fine when stationary however, when I move, the shader pixels are stationary on the screen. Is there a way I can make them move opposite to the camera so that the pixels stay where they are in the world like a normal 2d game. Like the camera is moving past a sprite and not the sprite flickering snapping to the nearest pixel?

You can try changing the anti-aliasing method in your project settings to fxaa, this should reduce the flickering
