Using Matchbox as a Transition
You can use Matchbox shaders as transitions in the Timeline. You can create your own Matchbox transitions or use one of the many transition presets, supplied with the application.
To use Matchbox as a transition:
Add a Matchbox transition.
The file browser opens at the location containing the shaders and transition presets.
Select a transition preset.
The shader is loaded as a transition and you are taken back to the Timeline. However, the shader does not yet behave as a transition.
Though the selected shader is marked "transition", it does not contain any of the animation or the parameter values that makes it behave as a transition. In order to get the transition effect, you can either manually create the transition animation or select one of the preset transition effects, from the Preset pop-up menu of the Quick menu, after having loaded the shader. This loads the animation data and parameter values necessary for a proper transition effect.
Select a preset transition from the Preset pop-up menu of the Quick menu.
The shader now behaves as a transition.
Make any timing adjustments to your transition.
