Final Cut Pro X on both iPad Pro & MacBook Pro behaving strange

When working with overlays video like a title or a PNG w/ transparency file, the results depend on the transition you have selected.

For example, if you apply the Cross Dissolve transition it will work as expected and the graphic will dissolve in and out.

If you apply something like the Flip transition to the overlay graphic it will not work as expected as it requires a source to flip from and flip to.

You can, however make the effect you want (such as a flip or rotation of the graphic) by manually keyframing it.

Please post a screenshot of your ti

and indicate which transition is being used. Yes, I know you said you tried them all but let’s focus on one that you intended to use.

I am thinking that probably things are working as intended, but just not as you would expect them to. But to be able to guide you to success we need to know more precisely what you are doing now.

You’ll need to share some screenshots of your project on the Mac. While some of the transitions you described work, not many do. I don’t see the issue in the current version of Final Cut Pro and macOS 15. Is the project on the Mac a transfer from the iPad?

"... it effects everything underneath."

This is how it should behave. If you want to isolate that transition to only that clip or image, put it with the transition inside of a Compound clip, that will isolate it from affecting anything else.

Which transition are you using?

I don’t understand. So you didn’t see if it works on the Mac?
