Final Cut screen replacement

How would a person do a screen replacement that the screen is curved? The screen is tilted on the x axis, distorted on all four corners, but the screen actually protrudes out in the middle of the screen. Imagine a building that is round and the top of the building has a screen that wraps around the building. How would someone add their own video to that screen. Most screen replacement is just adjusting four corners, but I need to distort the middle of the screen. I have found a way by using Pixelmator and Final Cut, and it is OK, but I wondering if I am missing something obvious. Sometimes I make things more difficult than it should be. What effects do you think I should be using. I have tried fisheye and a few others in Motion, but it does not manipulate the dimensions of the video. I manipulates the video itself. Any thoughts?

Mac Studio, macOS 15.1

You can try this:

https://fcpxtemplates.com/cylinder-surface/

it's free...

How you would use it is apply it first to the footage you want to fit on the screen, then apply the four corner effect (if you use a separate Effect template — the four corner Distort transform is automatically applied after any effects you add to the footage.)

It has Position, Rotation and Scale parameters (and one called Unwrap Amount which will *flatten* the curvature as you increase the value.) Dial down the disclosure triangles to access Z translation and X&Y rotations if the viewpoint changes over time.

Since curved screens are "inside" views of the "cylinder", you will need to set the Scale X parameter to a negative value to flip the image to the correct orientation.

YMMV — HTH
