Unable to drag and drop video from video album to desktop. Possible iOS bug?

[hajime]

Hello, I imported a video from iPhone 6s+ to my Mac. It shows up under album->video. I am unable to drag and drop it to my desktop. Could you please let me know how to do it? Thanks.

I take it that you've imported the video into Photos? What happens when you try to drag and drop?

Yes. I imported the video into Photos. For photos, I could move (created?) one on the desktop by drag and drop. For videos, most of the time nothing happened. Sometimes the fan kicked in. One time, after a long wait, it showed up on the desktop. For a 115MB 4K video, I think it took over 30 minutes for it to appear on the desktop.

This is really strange. After I used the method in the following thread "iPhone 6s+'s memory is behaving strangely" to "really" delete the photos and videos to regain the storage on my iPhone 6s+, I can copy the 4k videos quickly from album to the desktop by drag and drop. Issue solved. Anybody knows what happened? Is this a bug in iOS?
