  Using Markers to loop Fade in/out

  Posted by Mark Warner on October 2, 2018 at 11:21 am

  Really need some help, please! I have to add a ton of subtitles to some footage. I found a great script that separates out the carridge returns of text so it’ll show one sentence at a time whenever I add a marker.

  I really want to add a text animator to this script to work off the same makers, ideally with a fade in and a fade out.

  The problem I having is that I need the fade in to start right at the beginning of the marker and the fade out before the end of the next marker. So I need one marker to control the fade out AND the fade in of the next sentence.

  Can’t find any examples like this, can anyone help!!?

  Thanks ????

  Try this:

  
if (marker.numKeys > 0){
fadeDur = .1;
n = marker.nearestKey(time).index;
t = marker.key(n).time;
if (time < t){
ease(time,t-fadeDur,t,value,0);
}else{
ease(time,t,t+fadeDur,0,value);
}
}else
value

  Thanks so much Dan, you’ve made that look stupidly easy (and has saved me hours :D).

  Massive thanks
