Does iMovie support exporting video as 4k 60 fps or only 30 fps?

I think I figured out what they were doing which still means iMovie only supports 4k30.

They are selected the clip in the clip bin that is 4k60, exporting that and getting a 4k60 video equal to the file they imported. Pointless.

When you drag the 4k60 video from the clip bin into the timeline, edit it, then try to export the edited video iMovie only gives the option to export as 4k, no 60. In fact, it also eliminates the option to export to 1080p60 even though the original video was 60fps.

I can take a 1080p60 imported video file, edit it, then export that edited version as 1080p60 though. So... There's tons of inconsistencies and flaws in the way iMovie handles 60fps vs 30fps videos.

For now I'm just sticking with 4k30 videos as it's still extremely good and the optical zoom on the iPhone X is pretty nice to have.

Hmmm... Now I have to figure out how. I have a 4k60 file that I'm trying to export, I've made every clip imported into it 4k60 but the file I end up with when opened in Quicktime states it's 4k30. I'll have to test with some smaller files so I can do it quicker, the one I'm testing with now is a 15 minute video file.

Thanks for the reply!

It doesn't appear you can export 4k60.

I took two very short clips in 4k60 on my iPhone X, imported it into my computer. The .MOV files I imported are confirmed as 4k60 as seen here:

That's the raw file from my iPhone. I then created a new iMovie movie, imported that and another file of the exact same settings into it.

I then exported that file to my computer and this is how it exports:

And that is from the exported file which I used these settings to export it of which there are no 4k60 options only 4k:

So would that tell me that there is no 4k60 ability of iMovie or am I doing something wrong?
