Hey -- I'm really not sure what quality of video I'm supposed to be uploading. I chose iMovie's 'webstreaming' option, but the sound and video quality is really pretty damn low, as you can see. Is there a good reason not to choose a higher resolution option?
Updated to add: Jed researched a bit, and apparently as high a resolution as you can do, up to the 100 MB limit. I tried re-doing this one -- the highest-quality option (uncompressed) was 200 MB, so no good. The next easy option was a bit less compressed than what I had before, so I went ahead and uploaded it. You may or may not notice any difference. Also uploaded supposedly much higher quality version of previous table running video (which was half the length).
