Template not working like preview shows

I doubt that it works under Final Cut, even if you can import the premiere file. It's an interesting aproach, but as @Marissa B. Joyner says, it does not work as intended. 

You have those placeholders, where you add your films and a number of PNG animations to mask parts of your films (placeholders) out. Scaling is done at the beginning because the parrot films did not match the placeholder size. The placeholders get moved around as required. There is somewhere a mismatch with the movement and the places where the films should be at a certain keyframe.

Either the contributor uploaded an intermediate file by error, or somewhere between version 2023 and 2025 of Premiere Pro was a change that makes the file incompatible. My guess is the first.

Thank you so much for your help!! I'm super beginner with Motion, but maybe I can plug this into my Final Cut and try it that way. Thanks so much again!

The asset ID is 1386709818. You should give that info too, that would avoid having to search for the asset, as the contributor has more very similar assets. 

I agree with you that it does not work as shown in the tutorial. I'm not sure why this is so, however. I've looked into some internals, but I'm missing the time to check exactly what happens.

There may be a helping hand in the Premiere Pro forum. 

You also seem to have a plan that includes these assets. The same contributor also has a MOGRT file that does this similarly. That may work better and may be more flexible. https://helpx.adobe.com/premiere-pro/using/motion-graphics-templates.html
