I'm a hobbyist who makes little videos for the amusement of family and friends, often set to music. I think the most hits I've had on any clip is in the order of 100. As a 'for instance' the last video I posted to Vimeo was of my granddaughter dancing to music from 'Frozen'. Watched by doting relatives (maybe more than once, let's be honest). Obviously not-for-profit. And Disney not one cent worse of as a result. Presumably, if I tried to post this now, it would get flagged, or does this pass the 'fair use' test?
