Low frame rate camera

Is it possibile to simulate a different low (9Hz) frame rate for a given camera?
I tried using:

Get Game User Settings -> Set Frame Rate Limit (setting it to 9) and then Applyin the settings but this didn’t just lower the frame rate but slow down the whole simulation process.

I need a different approach.

I think you need to simulate it with a post process. Here’s an example of making it look like and old movie:

I’m going to check it on my app… thxn right now.

I probably messed up something but with the whole BP the only thing I get is the texture sample image (overlay) at the center of the screen.
