FCP won't share 2880x1800 video
I created a video screen capture - using QuickTime. The native resolution is 2880x1800. I have the video in FCP. I've adjusted the video to a resolution of 2880x1800 by highlighting the Project in the the following way (screen capture below). However when I try to Share this video I do not have an option to share at 2880x1800 when choosing.
File --> Share --> Apple Devices 4k --> Settings
I have a 1920x1200 option - but not 2880x1800.
Is there any way at all to just export the original resolution?
