Some background… I live in a rural area, and the fastest upload internet speed available is 300Kbps - AND it's capped. You can imaging what uploading 4K/30fps is like, so I avoid iCloud. I can use an iXpand drive to record on my iPhone X, and transfer the file to LF on my iPad, but only to 1080P and 60fps ) a limit of the iXpand). I'm trying to find a workflow to permit at least some 4K/30fps video to be moved from my iPhone to the iPad and LF without using iPhoto.

SO I turned off iPhoto uploads, recorded a few-second video sample at 4K/30fps, AirDropped it to the iPad, and loaded it into LF. I then deleted the raw file from iPhotos on the phone, as well as from the Deleted Files folder. (iPhoto will upload a deleted file from the Deleted Files folder unless you delete THAT file, too). It worked! And I had no problem in editing the file! But when I export it, the file is only 88KB and is all black. It should be about 39 MB, according to the Export window on LF. I tried exporting at 720P as well, and I got a 32KB file, again all black.

SO my workflow gets the file into LF, and it edits fine, but the export is screwed up. Any ideas?

Just to be clear, you deleted the video from your iPhone, but it’s still on your iPad where LF is installed correct?

If that’s true, then I’m not sure what the problem could be. If you deleted it from your iPad after you imported it LF then that’s kind of expected. LF doesn’t import the file, it simply references it from your camera roll. If you delete it from your camera roll, it’s gone from LF.

Oh, yes. I deleted it from the iPhone AFTER importing it to the iPad, and then into LF. It was NEVER on the camera roll; that was the reason for this whole workflow - I wanted to avoid uploading unedited video to iCloud because of slow transfer rates. I edited it in LF without problems. THEN I deleted it from the phone, and AirDropped the video to a Mac. Indeed, it's still running fine in LF on the iPad. Strange. I also made a copy of the edited file and exported it to the Rendered Movies folder on LF on the iPad. It's black there, too, so I know the problem was not in the data transfer to the Mac.

A puzzlement.

- iphone 7 : video 4k 30fps
- open in “scandisk”
- put “scandisk” on my Ipad
- open in Lumafusion
And it is OK

Is you video encoding H264 or H265 ?

Ahhh. I screwed up. The source media had been deleted before export. What confused me was that the files were in the editor and could be edited despite having been deleted. I speculate what you are editing may be a lower resolution version of the source material, and that at the time of export it draws upon the original video files. Since they had been accidentally deleted, there was nothing to export. So the lesson is do not delete any of the original video files until after you export, as well as make an archive.
