4.20 exposure with sequencer

Hi, does anyone know the proper way to set exposure on a camera and the play window so that when you render a sequencer animation it looks the same?
I remember in 4.18 I just set the exposure min/max brightness to the same value and the exposure value under [lit], in the window and it would look the same from working scene to render.
I feel like I’m just putting in random values into the exposure to get things to line up. any help would be great thanks

For me it is taking the values i have adjusted in Post Process Volume
