The Live Photos feature has been around for the last several iOS versions. I know some people really like it, but I find it to be a major distraction. I do not use it on my iPhone. When I receive a Live Photo from someone, I usually turn off Live Photos on that image. If you are not a Live Photos fan, you can turn it off on any images in the Photos App in macOS. This will convert the photo to a still image. This article explains how to do that.
