Position Time Scale
This returns the value of the Position at the Time Scale specified (for example, 0.5 is the value
at half the current frame time).
Position Time Offset
This returns the value of the Position at the Time Offset specified (for example, 10 is 10
frames back).
Offset Time Scale
This returns the value of the Offset at the Time Scale specified.
Offset Time Offset
This returns the value of the Offset at the Time Offset specified.
Example
This is a simple comp to illustrate one potential use of offsets.
1 Create a new Comp 100 frames long.
2 Create a node tree consisting of a black background and a Text node foreground
connected to a Merge.
3 In the Text Layout tab, use the Center X control to animate the text from the left side of
the screen to the right.
4 Move to frame 0.
5 In the Text tab in the Inspector, right-click the Size control and select Modify With >
Offset Distance from the contextual menu.
This adds two onscreen controls: a crosshair for the position and an X control for
the offset. These onscreen controls represent the Position and Offset controls
displayed in the Modifiers tab.
The size of the text is now determined by the distance, or offset, between the two
onscreen controls.
6 Drag the X onscreen control in the viewer to see how the distance from the crosshair
changes the size of the merge and by association the text.
Both the crosshair and the X onscreen controls are animatable and can be
connected to other controls.
7 Position the X centered at the bottom of the viewer.
8 In the Inspector, select the Modifiers tab.
9 In the Offset on Text size section, right-click over Position and choose Connect To >
PathConnect the position value of the Offset to the existing path by right-clicking the
Position control and selecting Connect To > Path1 Position.
10 Play the comp to view the animation.
Now, the text shrinks near the center of the path (when the distance between the
offset and the path is at its minimum) and grows at its ends (where the distance
between the offset and the path is at its maximum).
