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)

Affine Transition

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

{{#ev:youtube|IAWMIL7c9K4}}

This example is created using 3 keyframes. The second keyframe is shown below with a Rotate Y value of 1800 (=180 degrees). Keyframe one and keyframe three both have Rotate Y values of zero.

Keyframe two

Timeline for this demo clip

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
