I was thinking about this the other day when I was downloading some videos from my Mini-DV camcorder. The DV cam looks great on my TV, but not nearly as good on the PC.
I'm sure many of you have noticed that some videos look like crap on when they're put onto the PC. There will be a lot of jagginess when an object in the video is moving. That's because the video is interlaced, and your monitor is not. In order to fix this, you have to deinterlace the video. But deinterlacing your video kills your resolution. The way deinterlacing works, it strips every alternating scan line out of your video. Then the remaining lines are doubled, to maintain the proper aspect ratio. This removes the "venetian blind" look in the video but leaves you with half the vertical resolution in each half-frame that you had before.
some info
Then I saw video that someone took with their Canon Powershot S2IS. The video was extremely sharp, since it is natively progressive scan. I think if you want something that makes nice videos to watch on the internet, make sure it is true progressive scan. Otherwise you'll just have a low-res video.
