I haven't been able to find much recent/good info so far. The tech changes so fast that stuff posted even a couple years ago is out-of-date. May be time to double-down on a more thorough search.
I don't know how to download through icloud.com. Do you also have to set the camera to backup to icloud, and then use itunes?
I copy pictures directly from windows explorer - the iphone folders into the folders I want the pictures in on my computer.
Don't use iTunes for this.
Log in to icloud.com on a computer with your Apple ID.
Click on Photos.
Select the video you want.
Click the download icon.
