Notes: This video comparison page can be taxing to some systems. For that reason--and to make the best comparisons--we suggest limiting simultaneous playback to two or three videos. The embedded video player sizes you see below are the default size provided by the embedded video code we copied and pasted from each site. We uploaded the same 1-minute-long, 95.5MB QuickTime (MPEG-4) test file to each site. Some sites allow you to choose a thumbnail for your video; others do this for you automatically.
