Newbie Question RE: combing

Had a question about the cause of the the combing / mice teeth / interlacing artifacts in this video from NPR's music site:

Wu Han Plays Tchaikovsky, Month by Month
Wu Han Plays Tchaikovsky, Month by Month : NPR Music
(I hope I'm not violating any rules by posting a link, here)


My question: is this due soley to not properly de-interlacing before encoding for web?

Or do these artifacts have to do with shooting in 30i vs 30p, or how a camera is deriving a 30p signal from its native 60i processing?

I'm obviously very new at this, reading everything I can. I'm looking to buy a camera to record classical musicians from a static position. I keep hearing about progressive vs interlaced as regards to motion, but I don't know if this applies to a static camera with a musician moving their arms/hands very quickly.

DVD and Web are my intended delivery media, (for which I've heard that I should go progressive) but I keep hearing that interlaced will give smoother motion to fast subjects.

Thoughts?

Deinterlacing will cause the mice to lose their bite. It's as simple as that and cheaper than an orthodontist.

When going to a progressive medium like the Web, you always want to deinterlace lest you be chomped on by rodents.

If you're going to a high resolution on the Web, you might want to shoot progressive, either 24p or 30p. Depending upon your transcoder, you'll likely throw away half your resolution if you deinterlace interlaced footage, but it won't be a rodent snack.
