Just a tip for anybody making their own videos. Progressive video modes are better than interlaced modes, i.e., 720p, or 1080-30p is better than 1080-60i when it comes to grabbing stuff in motion. The difference works like this: in interlaced mode, a screen's worth of information is captured first with vertical lines 1, 3, 5, 7, 9, etc and then comes back and grabs lines 2, 4, 6, 8, 10, etc. So one field is odd lines, one field is even lines, two fields making a frame that happens approximately 60 times a second in 60i mode.
With progressive video modes (like 720p or 1080-30p), each line of each frame of information is captured sequentially; 1, 2, 3, 4, 5, etc.
The problem with interlaced video modes from a resolution standpoint is that the object in motion moves between fields. When an interlaced video gets displayed, it has to be "de-interlaced" - there are various ways of doing that, all of which involve degrading the resolution. You would think that 1080 lines of vertical resolution would be better than 720 lines, and that might be true with a static shot, but it's not necessarily true with an object in motion. By the time you deinterlace 1080i video of an object in motion, overall resolution may be less than 720p. Add in the fact that a camera bolted to an airplane may be vibrating, and you get even worse video.
ESPN shoots in 720p mode and it's not just because it involves less bandwidth. Each frame of video is a complete snapshot in time so fast moving objects are always captured as individual snapshots rather than trying to patch a screen of odd and even lines back together. If you've ever noticed jagged edge effects on diagonal elements in video (like a wing at an angle), you've noticed interlacing effects.
Another thing to bear in mind is that youtube usually de-interlaces video sent up to them, i.e., take 60i video and make it 30p, and if they happen to start that process on the wrong line your video appears degraded. They also typically do a 4 or 5:1 compression stomp on anything you send up so if you're sending up interlaced, low-bitrate encoded video, your video looks like crap by the time youtube gets done with it.
So the bottom line is, set up your gopro or whatever camera in 720-60p or 1080-30p and you'll get better results
