VidPaw offers up the usual features but on a relatively spartan interface. Though it shows how YouTube might someday crack down on these things—VidPaw's own tutorial video, hosted on YouTube, was "no longer available because the YouTube account associated with this video has been terminated." For now, however, the site works with 1,000+ other sites. It doesn't offer video/audio combo downloads larger than 720p MP4s; you can get the video alone as a 2160p WebM format if you desire.
