So to the point:
24 fps
Credit file of 8927 vertical pixels
to be rendered in apple pro res 422

Thanks in advance.

PS: My math is a little rusty (and by little I mean a lot), so if it isn't too much to ask, lets keep the math talk in layman terms.

Thanks again

i'll assume that you just want smooth movement....

there are two easy ways to ensure that you get whole pixel movement (to avoid the 'wavy' anti-alias text issue).

one way is to add this expression to the position property:

offset=2; //value in pixels per frame

set the credit layer's position at it's inpoint to off-screen bottom (or where ever you want it to start), and it will march up the screen until the end of the comp/layer. adjust the offset variable as needed, but you'll probably need to keep it less than 5 or 6, or the text will get start getting hard to read...

another way that is easier for many to work with for timing is to create 2 keyframes for position that are 1 frame apart. set the y value for the second key frame to be the number of pixels per frame movement that you need (say 2 pixels).

then add this expression:


the movement will not happen until time hits the first keyframe, so timing can be adjusted in a more familiar way, then the code just continues that movement. you might add this animation and expression to a null, then parent the credits to the null to make it easy to adjust the credit position separate from the animation.
