Under what conditions does iMessage downgrade shared video quality?
I noticed that when sharing videos to a group iMessage the video quality was significantly downgraded, while sharing the same video directly to an individual recipient didn't cause a quality downgrade.
As a specific example a 30.2Mb HEVC video got reduced to a 24.3Mb H.264 video and the converted video quality was awful. Wanted to see if there is a setting to turn off auto downgrade of videos when sharing.
