at least for things filmed with modern HD cameras. 60p (60i, really) for VX footage is somehow OK, but man, I've been reverting 60p 720p stuff down to 480/30 for years now. just wanted to see how many others do this.
I think the real question is why doesn't YT just offer a 720 or 1080/30 option... probably no one besides skaters care about this shit.
