iMovie - 1080p Export Not Available
I'm trying to create simple slide shows of images with simple zooms and transitions. The source images are all larger than 1920px x 1080px.
I have tried the various workarounds without success. I have also deleted preferences and started from scratch.
If I start a project, insert a 1080p clip then try to export a file I have an option to select 1080p 60fps.
If I then start adding images, keeping the 1080p clip in the project, I no longer have the option to select 1080p.
If I then start adding images, deleting the 1080p clip in the project, I no longer have the option to select 1080p.
On Mojave and 10.1.9... only updated as had same problem on previous operating system.
iMac, macOS Mojave (10.14)
