  Time Remapping with markers

  Posted by Kirill Komrakov on October 29, 2019 at 11:33 am

  Hi!
  I need some help with this expression.

  It binds 4 keyframes to 2 markers, but the time between keyframe 2 and 3 freezes. What i am trying to do is to when you move markers time in between should act like when you move two last keyframes with normal time remapping – time between keyframes 2 and 3 just speed up. Thanks!

  The idea just to move markers to get same result as moving keyframes without constantly hitting “U” button.

  T = thisLayer;
if ((T.marker.numKeys > 1 ) && (numKeys > 3)){
sIn = key(2).time - key(1).time;
sOut = key(4).time - key(3).time;
eIn = T.marker.key(1).time;
eOut = T.marker.key(2).time;
if (time < T.marker.key(2).time)
linear(time,eIn-sIn,eIn,key(1).value,key(2).value)
else
linear(time,eOut,eOut+sOut,key(3).value,key(4).value);
}else
value;

  I’m not sure if this is what you’re looking for, but try this:

  
T = thisLayer;
if ((T.marker.numKeys > 1 ) && (numKeys > 3)){
sIn = key(2).time - key(1).time;
sOut = key(4).time - key(3).time;
eIn = T.marker.key(1).time;
eOut = T.marker.key(2).time;
if (time < eIn)
linear(time,eIn-sIn,eIn,key(1).value,key(2).value)
else if (time < eOut)
linear(time,eIn,eOut,key(2).value,key(3).value)
else
linear(time,eOut,eOut+sOut,key(3).value,key(4).value);
}else
value;
