Alex4D Switch Channel
This item / tutorial is available from the Creators website using link below
A free Final Cut Pro X transition that simulates an analogue TV switching channels between shots.
Use this transition to imply a change in content. Changing the channel means the outgoing subject is over, it is time to move on to the incoming subject. 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.
