Photos – How to Filter Live Photos on macOS and iOS

It's quite easy:

1. close iTunes if it is open
2. have your smart albums created on photos app
3. still on Photos, create a new folder and named it with a unique name like
4. "Vacations 2018"
5. click on your smart album(s) and drag it(them) into the folder you just created
6. close the photos app
7. open iTunes, go to File -> Home Sharing -> choose photos to share with AppleTV
8. Select Share Photos from: Photos
9. click on Selected Albums (Select "Inlude Videos" checkbox if you want them played as well)
10. In the Albums collection, click on the folder you created at the beginning (Vacations 2018)
11. click the button Done at the bottom of the screen
12. close iTunes
13. Go to your AppleTV and select Settings -> General -> Screensaver -> Home Sharing -> Type -> Home Sharing -> Home Sharing -> Photos -> Photos. Confirm that you want to set photos as your screen saver
14. go back to the screensaver windows and choose the Preview option to confirm the photos are corrected select and displayed.

That's it!

You have to import the two files of the same picture (the photo and the video) with the same name.

Photos will recognise them as a live picture then.
