Alex4D Switch Channel is a Final Cut Pro X transition that simulates an analogue TV switching channels between shots.
You can control whether the clips roll up or down during the switch, how much the clips wobble up and down and what proportion of the transition is of used to show the clip moving up or down.
To show an aside or interruption, use the opposite direction roll when returning to the main subject. For example, if you use Alex4D Switch Channel to roll down to an aside, use it again with the same settings apart from rolling back up to the main subject.
