quote: Evans, I was under the impression that those shooting Super 35, like Cameron, were shooting 3-perf pulldown Super 35. (Look here for nice diagrams of the different 35 and Super 35 formats) Once I read your post, what Dave was saying makes sense to me. Since Super 35 3 perf is a possiblity, I don't really understand why you wouldn't use it, unless you are making a big consideration for the home video market, which Cameron undoubtedly is. Thanks for the clarification.
quote:
In general, 3-perf pulldown cameras are most often used for film being shot for television, rather than feature films.
I'd never heard of 3-perf super35 until the post I quoted above. As for John's comment, why would anyone want to use 3-perf for TV? Using 4-perf yields the TV aspect ratio. Wouldn't using 3-perf require cropping of the sides of the image to get the image to fit the TV (unless you're talking about HDTV), wasting image area on the negative? 3-perf would work for HDTV, though. ------------------ Evans A Criswell Huntsville-Decatur Movie Theatre Information Site

For television production, 35mm 3-perf uses a "Super 35" width camera aperture of 0.980 x 0.546 inches. The image area transferred to 16:9 video is 0.910 x 0.511 inches. For 4:3 video, the area is 0.680 x 0.511 inches. The format is used to save stock and lab processing costs, while having the largest available image area for the growing 16:9 video format. For today's TV shows, the important action is kept within the 4:3 area, or the image is letterboxed on 4:3 televisions.------------------ John P.

Dave, you seem to have some strange idea that scope is inherently better than flat, and that everyone should agree with you. This is a really poor premise to start with.The decision for scope versus flat is an artistic one. Yes, economic and practical factors show up, too, but it's a fundamentally artistic choice. It is never inherently wrong to choose a particular format. I think it's also a little disturbing how people are pigeonholing directors and producers on aspect ratio. It may be a religion for some, but that doesn't make it a religion for all. --jhawk p.s.: Minority Report is Scope.

JHawk said: "...you seem to have some strange idea that scope is inherently better than flat, and that everyone should agree with you. This is a really poor premise to start with."Because of the larger image area, "Scope" IS usually better than "Flat" for image quality. A larger image area on the camera negative reduces the manification of the grain and improves sharpness. A larger image area on the print allows more efficient use of the light, and less concentration of radiant energy on the film frame. I do agree that the aspect ratio chosen for a film should be an artistic decision, rather than an economic one. But the limitations of video display sometimes push producers toward pictures that are less wide in hopes of maximizing the video market.  There are better ways of achieving a 1.85:1 aspect ratio than simply cropping the image area:  http://www.kodak.com/US/en/motion/newsletters/reel/february97/pytlak.shtml ------------------ John P.
