Types of video files stored on iCloud that play without having to download first
I want to transfer my videos from Google Drive to iCloud to take advantage of all the space I bought with Apple One Premier. So far, videos that are in MPEG-4 and MP4 formats will play by clicking on them, but an M4V or MPEG download themselves without playing.
Can anybody explain this to me? Is there anything I can do for these common videos types to play in a window rather than downloading them?
Thanks
