Title scroll flicker

[Andrei Zagdansky]

David, thanks.
I feel like I am a bit over the top. How I do this? Calculating number of frames per scroll?

[Andrei Zagdansky]

David, thanks a lot.
Will try. I have a 25-frames advantage in my case, but still it doesn’t look like a lot of fun.
will keep you posted with regards to my progress. 🙂

BTW, Do you know a better way to make a scroll?
Thanks!

This thread from the main AE forum on the COW may help you. There are some expressions used and several suggestions given (i.e. Mercury Jones) that will probably be of use and may save you some time.

(I found the thread using the oft-neglected search feature of these forums by searching for smooth scroll or smooth credits, I forget which.)

sorry for the loss of the mercury jones preset… i found that it tended to create confusion and that a simpler approach may be easiest (i kept adding options to that preset based on requests/feedback and it just started getting a bit too complicated and created too much confusion)

here is a simple expression that will create a flicker free roll, allowing you to set the pixel/frame rate that you want:

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)];
}else{
value;
}
}else{
value – [0,rate*timeToFrames(time-inPoint)];
}

jsut position the roll where you want it to start and it will march up the screen at the rate that you set. even rate values should be used if you are rendering to an interlaced format, and if you set the rate too high the roll will appear kind of strobe-like.

you can add a layer marker to delay the roll if needed — maybe ‘the end’ dissolves in and then starts rolling up the screen with the credits…

Excellent strategy, it worked for me (pal and hdv)

BUT don`t forget to turn the field rendering on in the render queue>render settings
