Updated: 12 May 2025
Extracts a modifier value from a node.
Extractor
Method #
This modifier extracts a single numerical value from another node. For some nodes, there are properties available specifically for the Extractor node, like the Face Tracker or Hot Zone nodes.
The output is a numeric value that can be further processed with other modifiers, or directly connected to a parameter in another node, using the operation method selected.
Parameters
These properties control the core behaviours of the node.
Parameter Details Current Value
Shows the current value of the effect. Cannot be directly changed.
Source Envelope
Which parameter is to be extracted from the Source Node input.
Modifier Operation
The operation to be performed on the targeted parameter.
- Add : Adds to the parameter value.
- Subtract : Subtracts from the parameter value.
- Multiply : Multiplies the parameter value.
- Replace : Replaces the parameter value.
Scale
Adjust the scale/range of the modifier.
Offset
Applies an offset (post scale) to the calculated value
The properties control the time at which the node is active. See Timeline for editing time segments.
Parameter Details Duration
Control the duration of the node’s time segment.
- Composition Duration : Use the length of the composition for the node’s time segment duration.
- Custom : Set a custom duration for the node’s time segment.
Node Time
The custom start and end time for the node.
Duration (Timecode)
The length of the node’s time segment (in time).
Duration (Frames)
The length of the node’s time segment (in frames).
Time Segment Enabled
Set whether the node’s time segment is enabled or not in the Timeline.
