Not sure how you are animating the noise, but generally you want to
animate it to look something like the desired distortation, so that
would be animating the z, maybe linearly, and then also within the noise
transform tab animate it up in y, so it continually rises, if that is
what you want. I usually find it best to use a simple expression in
these cases. It also helps to have 2 or 3 distorts with different speeds
and different noise field scales, to sort of add layering and make it
more dynamic. Also, maybe use some subtle blur or iblur, plugged into
one of the noise field

I'm trying to use the noise & idistort to make my background have some
engine's heat distortion ( but it has to look like "boiling heat"
instead of wiggling x&y). The idistort seems like doesn't do the job
well. anyone has better idea?
thanks,
