For the purpose of expressions, markers are a special type of Key object, so you can use methods such as nearestKey(time) to access markers, and markers also have time and index attributes. Copy your new keyframe and paste it over the keyframe that Time Remapping created, so that there are two of the same keyframe ending the layer's Time Remapping. Many tasks in animation can benefit from looping (repeating the same thing over and over). Counter Time Expression.

One where I need the comp to start, second where it ends. 1. In addition to accessing values at certain times, After Effects allows you to access values at certain keyframes or markers. See below Over the years I have learn that after effects expressions can be very handy and powerful to make great motion graphics. The index attribute is not the number (name) of the marker; it is the keyframe index number, representing the order of the marker in the time ruler. Use a slider control to delay keyframe animation by a defined amount of seconds. While this After Effects tutorial is easy to follow, it might be a little difficult .
