Returns the value of the Audio Levels property of the layer, in decibels. This is a 2D value; the first value represents
the left audio channel, and the second value represents the right. The value is not the amplitude of the source
material’s audio track; instead, it is the value of the Audio Levels property, which may be affected by keyframes.
timeRemap Return type: Property.
Returns the value of the Time Remap property, in seconds, if Time Remap is enabled.
marker.key(index) Return type: MarkerKey.
Argument type: index is a Number.
Returns the MarkerKey object of the layer-time marker with the specified index.
marker.key(name) Return type: MarkerKey.
Argument type: name is a String.
Returns the MarkerKey object of the layer-time marker with the specified name. The name value is the name of the
marker, as typed in the comment field in the marker dialog box, for example,
marker.key("ch1") . If more than one
marker on the layer has the same name, this method returns the marker that occurs first in time (in layer time). The
value for a marker key is a String, not a Number.
This expression on a property ramps the property’s value from 0 to 100 between two markers identified by name:
m1 = marker.key("Start").time;
m2 = marker.key("End").time;
linear(time, m1, m2, 0, 100);
marker.nearestKey(t) Return type: MarkerKey.
Argument type: t is a Number.
Returns the layer-time marker that is nearest in time to t. For example, this expression returns the time of the marker
on the layer nearest to the time of 1 second:
marker.nearestKey(1).time
This expression returns the time of the marker on the layer nearest to the current time:
marker.nearestKey(time).time
marker.numKeys Return type: Number.
Returns the total number of markers on the layer.
name Return type: String.
Returns the name of the layer.
Layer 3D attributes and methods
orientation Return type: Property [3].
Returns the 3D orientation value, in degrees, for a 3D layer.
rotationX Return type: Property.
Returns the x rotation value, in degrees, for a 3D layer.
rotationY Return type: Property.
Returns the y rotation value, in degrees, for a 3D layer.
