End Credit Flicker.. (I know, I know!!)

Hi all,

I am currently animating the end credit crawl for a BBC drama. The credit list is huge and the time I have to get it up the screen is tiny.

The vertical change is 7710 pixels
The time is 700 frames at 25fps
The font isn't Gill Sans, around 15pixel.
Running an i7, 12GB Ram, Nvidea Quadro 3800
Rendering to Quicktime PNG
No broadcast monitor, just my Dell 30" Ultrasharp monitor.

I've tried solutions on here and other forums like the -

rate = 2; //value in px/sec.
if (marker.numKeys > 0){
if (time > marker.key(1).time){
value - [0,rate*timeToFrames(time-marker.key(1).time)];
value - [0,rate*timeToFrames(time-inPoint)];

- expression and its many variations to no avail. The rate I need to input to get the roll off the screen is 11 and a test render showed it to render two, vertically offset, low opacity copies that travelled up the screen together... odd..

I've tried the more simpler expression

Another post said that it can be benificial to render at double the frame rate and then time re-map the video with frame blending, this just rendered a very low resolution motion-blur type effect and without frame blending still looked very flickery.

I'm getting the impression that it is just too damn fast.

I hate to ask, but is there a plug in for after effects that reduces flicker in these situations? Or another work around. I've tried Dave LaRonde's mathmatical approach but couldn't tweak my keyframes so I reached an attractive integer.

Any help on this already well documented topic would be really, really appreciated

I hate doing credit rolls in AE. It may be simpler just to bring the credits into a character generator and do them there. This requires going to a production house.
