You're right - not ideal to manually transfer. Maybe iCloud will offer transcoding as a service next haha.

Many smartphones support recording H.265 encoded video directly and the resulting file size is tiny and quality is amazing. Not sure if it's the default setting (or possible) on iPhones though.

Yes, iPhones support recording to H.265 directly and have defaulted to it for a while.
