How to transfer slo-mo video from mac to mac in photos.app with slow motion editing options?

I have a slo-mo video imported from iPhone in my photos. Now I have to transfer it from my mac photo to the other mac photo.

I tried exporting my video as a file in the finder and then importing it back to the photo application. The slowdown video works as expected at correct timing, but the edit mode is lost. namely: we cannot change the tempo or frame of the slow motion later.

What can you do if you need to re-import the video with the slo-mo frame editing options available.

In the Finder: Create a folder for the media you want to transfer. In the app. Photo: Select the media you want to transfer. In the menu bar, select File > Export > Export Unmodified Original For… Select Export Choose the folder from the first step Transfer the folder from step one to the Mac where you want to import the photos In the Photos application on that Mac: In the menu bar, select File > Import… Select the folder exported from step 1 Select Review for Import Follow the dialog. To enjoy. (But do note: If you’ve made a change to the slow motion segment, it will reset to default after export. I’d like this to be changed, but I’m assuming we’re in favor of Apple for that …)
