Affine Transition
Generates image rotation in 3D space, skew and distortion.
Provides keyframable animated affine transformations with dissolve functionality.
In many applications this transition can be used instead of a Composite transition and this provides a workaround to the composite transition "green tinge" bug reported by some. (Mantis #2759)
Example 1
Disolve using Affine Transition
To add a dissolve change the opacity to zero percent.
Rotation using Affine Transition
To rotate the image add a keyframe and enter values for rotation. The units are 10ths of degrees. (e.g. 900 = 90 degree rotation).
Rotate X rotates the frame in the plane of the screen.
Rotate Y and Rotate Z create the illusion of 3D rotation when used dynamically with keyframes - see example below.
You can create a similar effect using the Rotate (keyframable effect from the Crop and Transform group.
Example 2 - Rotate Y
This example is created using 3 key frames. The second key frame is shown below with a rotate Y value of 1800 (=180 degrees). The key frame one and keyframe two both have rotate Y values of zero.
The difference between rotate Y and rotate Z is that the apparent rotation in rotate Y appears to be around a horizontal axis. The rotation in rotate Z appears to be around a vertical axis
