Tangential but, at least for me, I find lots of video creators making 2-3 gig videos for no noticable difference in quality for me re-encoding them to 1/4th the size or less.
My impression is, their audience equates file size with quality so the bigger the file the more "value" they got from the creator. This is frustrating because bigger files means hitting transfer limits, slower to download, slower to copy, taking more space, etc...
