Admittedly for some of the last 2, since many people have smartphones but it's harder to figure out how to record content ( heck for many people even if it's playing on their computer ), some of these Youtubes videos may be somewhat unique in that you can see the phone moving etc . ( In some cases only the shittiest recordings can survive due to Youtube's copyvio detection although I haven't actually seen those for a while so maybe it no longer applies . ) But in most cases people aren't interested in that and if anything would prefer a quality direct recording.
