I cannot export videos to camera roll using iPhone XS Max. I can use all of the editing features and begin the export process, but the progress bar never moves and I have to force close the app. I waited 20 minutes today to see if something would happen, but nothing did...the progress bar didn’t move.

I managed to actually get to the point of exporting the video once but it crashed when trying to choose the starting frame. Also it didn’t upload in the 4K format to YouTube that the project settings were set to but that could be due to the crash. After that I had no luck to even get close to exporting a video the app just crashes when using the iPhone XS Max.
I opened the project on my iPad Pro but when trying to export I get a warning that media is missing. It doesn’t tell you what media though.
So I finally got to export the video from my iPad Pro. Even though I get warnings that there is media missing I can’t see any difference also the estimated size is larger, 2GB, without doing any changes except removing the music. I exported it to YouTube and everything went smooth but it took about 30 min for a 4:27 min clip but it’s 4K so..., I can confirm that it’s 4k on YouTube. I’m not really sure what’s going on here but maybe the app isn’t adapted enough to perform well on iPhone X and XS? I’ve seen this with other video editing apps. The iPhone gets really hot whereas the iPad doesn’t so I’d guess it needs tweaking. For me the copy that goes to my camera roll is 4K. I verified it by downloading the file from my camera roll to my w10 pc and then checked the preferences of the clip.
