Simulate Rolling Shutter Effect

Hello! So usually you reduce rolling shutter effect in the footage, then track it and add cgi to it.
But I've decided to make a very realistic live action CGI. Adding a rolling shutter effect to my 3d render would add that cool "hand-held camera" look and make viewer feel like it's really in the shot. So, obviously, the problem is that I don't know how to add this effect in After Effects
Any ideas?

Effect --> Time --> Time Displacement based on a simple gradient.

Tried what you suggested. Used this gradient.

And got a very jagged result. The settings I used are: Max Displacement 0,1; Time Resolution (tried a lot of values)

For handheld result you can paste a tracker from
a real crap handheld footage and stabilise by that.
For rolling shutter maybe you can animate puppet
pins back and forth with high frequency. I guess there
is some expression you could use to normalise their
motion (use steady pins at the bottom and 2-3 shaking
ones at the top.).
Check the wiggle effect here for the pin animation
Seems this is the expression we need (sorry if i'm wrong, i'm not
good at scripting).

Thanks, it may be a solution.

Glad to be useful. I think some vertical wipe
effect i see in a phone's camera is missing from
the method i suggested. Good luck.
