I use an iPhone, and when I take my pictures off the phone, I usually capture the entire Live Photo. This is an Apple thing (introduced in iOS 9) that consists of two items with the same file name:
an image: JPEG or HEIF, depending on device settings, and
a video: in a QuickTime .MOV container, encoded with either H.264 or H.265, depending on device and/or device settings; not to exceed three seconds in length.
optionally, an edits file: a plist file in XML format with a .AAE extension describing the edits done to the image so that they can be reversed at a later point. This would only make sense to Apple devices and is not required for Shotwell, but I may as well mention that it may or may not exist, too.
For example, I might import IMG_0001.HEIC, IMG_0001.MOV, IMG_0002.HEIC, IMG_0002.MOV, and so on.
All my Live Photos are HEIC/H.265 so I can't test behavior at the moment with native files due to issue #8 blocking HEIF imports. However, I converted one HEIC to JPEG and Shotwell treated them as two items. I feel that Shotwell should recognize these two files as a single item and show them as one.
Adding support for viewing the photo and video, or even changing the photo to a different keyframe from the video (as you can do on iOS) would be an advanced feature that isn't totally necessary to have in Shotwell. Just recognizing them as a single item would be good enough for library management, which is the most important thing.
