Brian recently wrote about problems he was having with transitions in Final Cut. As we talked, I realized that his problems could probably be fixed by editing the transitions in Motion.
So, as a general example, let me show you how this works.
NOTE: This process is the same for all FCP X Transitions, Generators and Titles. Some Apple effects can also be modified. Generally, though, 3rd-party effects are locked and not modifiable.
Here, I’ve applied the Flip transition to two clips. Except… it would look better if it had a background and the flipping motion was in a different direction.
So, let’s tweak.
Control-click the Flip effect in the Transition Browser and choose Open a copy in Motion.
This opens a copy of the effect in Motion. Why a copy? Because we can’t modify the original effect from Apple, but we CAN modify copies.
Let’s start by adding a background.
NOTE: If all you want to do is make the background transparent, so that you could add your own background in FCP X, simply uncheck the Background group, then jump to the end of this tutorial to learn how to save it.
In our case, we want to replace the black color solid of the current background with something more interesting.
NOTE: When dealing with backgrounds, it is often easier to apply effects to the containing group than the background element itself because many animated backgrounds are multi-component particle systems.
NOTE: You will need to increase the Zoom slider. The goal with this effect is to make sure that in the brief time the background is visible it is obviously moving.
MODIFY THE TRANSITION
There is an almost unlimited number of things we could do to the transition itself. As I was practicing for this tutorial, I created a 75 step animation. That would, perhaps, be a bit excessive for this tutorial.
So, let’s try something simpler – rather than have it rotate around the Y-axis, we’ll have it rotate around the X-axis. However, you are free to play as much as you want. Since this is a copy, nothing you do to this will affect the original effect.
However, as it does so, the second image ends up upside-down. Sigh.
Play the transition and see the results of your work.
SAVE THE NEW TRANSITION
If you simply choose File > Save, you’ll save this copy of the original transition back into Final Cut. However, I prefer more control.
Choose File > Save As.
This displays a screen allowing you to give this effect a more meaningful name and, more importantly, decide what Transition category to save it in. I’ve created a category for all my custom effects, which I call “Larry” because it is an easy name to remember. At least for me.
NOTE: You can name categories anything the macOS will support.
I generally don’t check the bottom two check boxes.
Now, when you go back to Final Cut, Transitions > Larry is updated with the transition you just created.
Apply it to your project and you are done!
NOTE: Once created, these custom effects will appear in the Transition Browser for all future projects.
As I was practicing, I used keyframes for both rotation and position and had these images flying all around the frame. If you know Motion effects, any effect can all be applied to these two clips.
Give yourself permission to play. The best way to learn Motion is to say: “Hmmm… I wonder what happens if I do… this?” I’ve discovered all kinds of cool effects that way. Some of which I even want to show to others.
All custom effects are stored in [ User Home Directory ] > Movies > Motion Templates. In my example, transitions are stored in the Transitions folder inside Motion Templates.
