God, I never thought I'd end up defending video, but there are just some pretty basic facts that are getting glossed over. First of all, resolution is measured in *horizontal* lines, not horizontal and vertical. Second, 1250 ll is one of many HDTV formats, and there are some with higher and some with lower resolution. The only HDTV standard with production equipment available is an 1125 line system. Third, Kodak-conducted tests indicate that the resolution of 35MM 5247 negative is comparable to a scanned image of 2330 lines (Mathias and Patterson, 231). NHK tests indicate that the human eye cannot perceive a difference in resolution above 1600 lines (231)--under the conditions of the test, which means super-ideal. Still, the question remains as to whether the technology reaches a certain point where its simply overkill. > The other problem is that, due to the limitations of the small screen, > (anything under 2 metres wide) the composition of the image needs to > be different than on the big screen.

I agree there are stylistic differences between video and film, but the implication here is that they are somehow innate to the technology. These differencesare culturally specific. While they have a context arising out of certain technological factors, there is nothing about the technology itself that dictates television to be a close-up medium, or film to be panoramic one. We have ascribed these differences to the media, without recognizing our own expectations, by simply remembering what we have already seen and where we have seen it. According to your argument, a person trained in video could not shoot in HDTV, since the aspect ratio of HDTV is 5:2. There are really two issues here; one involving composition that doesn't have anything to do with the resolution of video and the resolution of film, and the resolution of a 70MM print like Lawrence of Arabia. Under current standards, video would not compare favorably to such a print. But that doesn't mean that a similar effect can't be created with a similar aspect ratio.
