@futurebird if it's something I'm interested in I will probably *eventually* watch it
my sweet spot is right between the first two options, between 10 and 20 minutes, and shorts-length (< 2 min?) is usually not really enough to enjoy it, but really, anything below 1 hour is fine, and stuff that is longer than 1 hour, but looks really interesting, may get split between more sessions, but still watched.
