Recent tests show that 50% of the HDTVs tested from Sony. Panasonic, etc. do NOT display more than 540-lines when fed 1080i. Despite some having 1080-rows of pixels -- the chips that do the deinterlaceing simply DO NOT output more than 540-lines of information to the display! (Same is true of CRTs!) That means all the 1080i you have likely ever seen in your life has been on displays that have a FILTER that removed the interlace artifacts. The newer de-interlace chips fix this problem. So what you don't see NOW -- may become very visible to someone who owns/buys one of the newer monitors. I'm doing a series on 1080i in HDV@Work for Video Systems. The first part has just gone on-line. I'll be covering these monitor tests and more in the coming month.

Steve, only 540 lines? that's interesting. Can you point me to some reputable reads/articles on that? If this is true, kinda changes perspective on what is shot today, and how it may look like when 'real' HD tv's hit the floor.

But what about interlace artifacts -- line-flicker and line-twitter -- I see on even broadcast HD. The new display chips should make these more visible. Shannon, if you have time -- can you try two simple tests. 1) shoot a brick building starting at wide. Now very, very, slowly zoom in. On playback -- do you see a point where some of the horizontal lines become so thin they exist in only one field and thus flicker at 30Hz? (You may not see them in the VF.) 2) shoot a brick building starting at wide. Now zoom until until you see the horizontal lines distinctly, but not so far they become thick lines. Now pan UP and DOWN the side of the building. On playback -- as you pan, do the hortizontal bricks seem to "twitter."

Shannon I was speaking purely on economies of scale. See if you have the amount of money to throw behind a movie that underworld took (or to be honest the amount of money for publicity) then totally cast the hot lead, but until that day comes, stick with the supporting actress theory... (especially in college/ filmschool)
So steve are you saying that the camera produces a better image in 24f then it does in 60i?
