I have a video in the Photos library of the Photos app on my Mac.
If I right-click it and select “Get Info” – it shows that the video is 1920×1080.
Next, I share it to iCloud Photo Sharing.
Then – if I right-click the resulting video in the Shared album – it shows that the video is now 1280×720.
So – how can I share videos without reducing the quality?
As a random aside… does anyone have any tips for how to search Google for help for an app as generically named as “Photos”?
It’s a limitation of iCloud Photo Sharing itself:
iCloud Photo Sharing supports HEVC, MP4, and QuickTime video file types, and H.264 and MPEG-4 Video file formats. Videos can be up to five minutes in length and are delivered at up to 720p resolution.
Unfortunately, there really isn’t any way around this right now.
