iMovie in 4K?

[snerkler]

I'm wanting to make a slideshow of some wedding photos that I've taken, photos are high res from a 50mp camera but when I go to export (share > file) the maximum quality if 1080p, is there a way that I can export at 4K please?

The maximum resolution you can export is that of your project. So…

Well the project files have far more resolution than 4k so....

I have actually found a workaround for now, if I add a 4k movie first then add the photos the project is then 4k, I can then remove the movie and it stays 4k. What I don't understand is why it won't recognise photos as anything over 1080?
