Altering Scrolling Credits Expression
Hello,
I found this expression below, which is great. Thank you to whoever wrote it!
The scrolling starts at the first marker and I was wondering if there is a way to let the scroll stop at a certain time or second marker. Please let me know, how to alter the expression, if it is possible.
rate = 5; //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)];
}

Here is one way to do it:
rate = 5; //value in px/sec.
if (marker.numKeys){
t = timeToFrames(time - marker.key(1).time);
if (t>0){
if (marker.numKeys>1) {
// more than 1 marker, stop scrolling at marker 2
value - [0,rate]*clamp(t,0,timeToFrames(marker.key(2).time - marker.key(1).time));
} else {
// keep scrolling
value - [0,rate*t];
}
}else{
value;
}
}else{
value - [0,rate*timeToFrames(time-inPoint)];

Thank you very much for your help!
