Found workaround for empty Camera Roll but flawed – LP - Live Image to Video & GIF Review

I unfortunately moved the live photos I wish to convert into another album. They are no longer in the Camera Roll -- the default location that LP loads. Even though I've copied the photos back to my iPhone in another Album, when I select "Album" to load photos from a different album, the LP app crashes. Eventually I found a workaround. Snap a "Live" photo. It's in the Camera Roll. Now LP finds the one Live photo in the Camera Roll and lets me search other Albums without crashing. However!... (1) The app does not preserve the correct orientation of the original photo. (2) The app doesn't even preserve the original aspect ratio!! The only thing preserved is some portion of the original photo and the metadata. I appreciate the latter, but the other flaws are unacceptable. I guess you get what you pay for. I suppose I need to write my own app.
