I think they’re great - absolutely perfect for situations with young kids who are constantly moving, or just to capture little vignettes of movement that bring a photo to life for a moment.
But support for them is virtually non-existent outside the iOS Photos app.
You can extract them as a pair of HEIC and MOV files, but I know of no Free photo management software that is capable of associating them and displaying them together (and yes, there are internal IDs in both files that make it possible to link them, so they aren’t quite as fragile as most sidecar files, although they are still fragile because Apple for some insane reason decided not to make use of the HEIF container format’s native ability to store both in the same file).
I’m unsure if Android has an equivalent feature or how it’s implemented, but I’m pretty sure no DSLRs have anything like it.
Pixel phones can take "Motion Photos" — it seems like this is basically just an mp4 file stuffed into a jpg somehow (but without sound). The Google Photos app lets you export it as an mp4 or gif file, or pick a specific timestamp to export a still image.
It looks like the Samsung Camera has something similar, but I'm not sure if it's compatible...
All of the current high-end cameras are pretty similar here and do around 30 fps stills shooting at full resolution or alternatively 8K (33 MP) video. Just 8K video alone is pretty much the same, as far as resolution is concerned, as yesteryears dedicated high-res bodies.
At the levels below that you'll have to settle for full-res stills at somewhere between 14 and 20 fps or 4K30p/4K60p, for now.
