  Connect camera position to a marker

  Posted by Ciji James on October 17, 2020 at 6:09 pm

  I’ve set three keyframes for my camera in my ae comp and I’ve marked them with markers. How can I recall the keyframes of the cam with expressions by referring to the markers?

  To access a position keyframe of the camera for example, at the first key:

  thisComp.layer("Camera 1").transform.position.valueAtTime(thisComp.markerKey(n).time)
  

  Markers can be accessed by number (the number is the order that they appear, not the number it is assigned to, which is actually its name), or by name, e.g.

  thisComp.layer("Camera 1").transform.position.valueAtTime(thisComp.markerKey("my marker").time) //or
  thisComp.layer("Camera 1").transform.position.valueAtTime(thisComp.markerKey("1").time)

  Thanks a lot stephen… am getting to understand expressions…

  I have three different key positions for my camera, which I have marked as blue, green & red to say. how can I call those values for my camera when required by just putting markers, rather than not adding keyframes… Thanks a lot for your reply
