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").Ifmorethanone

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

Returns the total number of markers on the layer.

name Return type: String.

Returns the name of the layer.

Layer 3D attributes and methods
