Image Aspect
This slider control is used primarily to compensate for image aspect differences. A square
image of 500 x 500 would use an Image Aspect value of 1, while a rectangular image of 500 x
1000 would use an Image Aspect value of 2. The default for this value is taken from the current
Frame Format preferences using width/height. It may be necessary to modify this control to
match the current image.
Example
1 Create a 100-frame comp.
2 Create a simple node tree consisting of a black background and a Text node
foreground connected to a Merge.
3 Enter some text in the Text node.
4 Select the Merge node.
5 In the viewer, right-click the Center control of the Merge and choose Modify With >
Vector Result.
This adds a crosshair onscreen control for the Vector distance and angle. The
onscreen control represents the Distance and Angle controls displayed in the
Modifiers tab.
6 In the Modifiers tab of the Inspector, drag the Distance control to distance the text from
the Vector origin.
7 Drag the Angle thumbwheel to rotate the text around the Vector origin.
This is different from changing a pivot point, since the text itself is not rotating.
These points are animatable and can be connected to other controls.
8 In the Inspector, right-click the Origin control and choose a path to add a motion path
modifier to the Origin control.
9 Verify that the current frame is set to frame 0 (zero) and use the Origin controls in the
Inspector or drag the Vector Origin crosshair to the bottom-left corner of the screen.
10 On the Vector Angle thumbwheel, click the Keyframe button to animate this control.
11 Set the Angle thumbwheel to a value of 10.
12 Go to frame 100 and click at the top-left corner of the screen to move the Vector Origin
crosshair.
13 Set the Vector Angle thumbwheel to a value of 1000.
14 Play the comp to see the results.
This causes the text to orbit around the path just created.
