[edit] Commen re the wide screen Ratio of Kinopanorama

I believe that the 2.72:1 wide screen ratio may be incorrect; further research, by myself or others, will be necessary before the final ratio is arrived at on the List of Film Formats.

On our Kinopanorama website (the external link of which has been temporarily removed from the Wiki entry on Kinopanorama by the undersigned for technical corrections, updates, and some cosmetic improvements; it should be back in roughly 10-days) shows the wide screen ratio as 2.77:1. This was based originally on a publication listing it thus by Mark Baldock in the UK.

However, both the 2.72:1 and the 2.77:1 have been disputed as well by Martin Hart of the American Widescreen Museum.

Martin Hart believes that the Kinopanorama ratio is almost identical to that of Cinerama. I have disagreed with him about this on several occasions, given that I own the Kinopanorama PSO-1960 camera and as it is within sighting distance from this computer screen I believe that I have some advantage over Martin in regards to this. Time will tell.

A parting comment to the person or persons who have added the List of film formats to Wiki: My highest encomiums to all concerned.--Kinopanorama widescreen 01:52, 15 April 2006 (UTC)

• Thanks for the critique! I think, IIRC, a large problem with extracting a "true" value for the AR of multi-projector systems is that there is always going to be a certain degree of overlap, which unfortunately means that one can't simply take the AR of one of the strips and multiply by three. If there's some good documentation or evidence that several were used, or that it tended to be within an AR range, then perhaps that could be noted, however.

[edit] Todd-AO.

On page seven of the List of Film Formats, the entry below Kinopanorama, is the name 70 mm. Actually, this should read as Todd-AO, which is trademarked name of the process, and the name by which it has always been called.

Would suggest, therefore, that the persons responsible for entries on this page make the changes. I refer you also the Martin Hart's website for further details.--Jslasher 02:43, 19 April 2006 (UTC)

There is an entry already on the list for Todd-AO, which originally was a 30 fps process, and thus technically distinct from modern 65/70. As there are several different names for the 24 fps variant (Super Panavision, revamped Todd AO, and often just plain 65mm or 70mm), it seemed to make more sense to leave that with a standard name. As you can clearly see, Todd-AO already gets credit prior to that, and with nearly identical specs. I will, however, make a note to the section so as to make this a little clearer, as it is a good point. Girolamo Savonarola 15:30, 19 April 2006 (UTC)

[edit] Kinopanorama Aspect Ratios

In order to insure that information on the Kinopanorama aspect ratio is correct on this entry, as well as the soon to be downloaded Kinopanorama webpage, I would like to suggest to anyone reading this Talk Page that if they are interested in verifying the aspect ratios "in the flesh", so to speak, the undersigned would be more than pleased to post to them gratis strips of the 6-perf Kinopanorama work-prints shot in Australia with the PSO-1960 camera. Keep in mind, though, that there were two Kinopanorama cine cameras manufactured, the SKP-1 (1956-57), which is a "clone" of Waller's Cinerama camera, and the aforementioned PSO-1960, which incorporates interchangeable lenses of various focal-lengths, and is designed along the lines of one of the enormous Technicolour 3-strip cameras of the 1940s.

Anyway, drop me a direct mail at fifcon@bigpond.net.au if you would like samples of the work-prints. Include your postage address.

How are you going to verify the overlap space? Girolamo Savonarola 22:28, 23 April 2006 (UTC)

[edit] Corrections to Kinopanorama Tech Specs

Dear Girolamo,

Just a note to remind you to correct the Kinopanorama tech specs on this page, so that they match those which you kindly downloaded for me on my jslasher talk page. The Kinopanorama website will be updated this weekend to include all of your corrections.--Jslasher 23:46, 24 April 2006 (UTC)

[edit] First Biograph film

The first official Biograph film is titled: Sparring Contest, Canastota, N.Y. (American Film Institute Catalog of Motion Pictures, vol. A). Yes, some less authoritative sources spell it "Canastoda", but given that the name of the town in New York in spelled "Canastota", which is more likely: that the Biograph founders who lived in Canastota in 1896 (Herman Casler, Harry Marvin) got the spelling wrong, or that later film chroniclers got the spelling wrong? — Walloon 18:48, 6 June 2006 (UTC)

Fair point. Conceded. The 1896 date may be wrong, however - according to http://www.victorian-cinema.net/harrymarvin.htm the tests were complete by June 1895, and it would appear that this is the sparring match referenced, esp. if it's the first film. Girolamo Savonarola 19:08, 6 June 2006 (UTC)

Actually, there were two sparring matches. In June 1895, to make the first film test of the Mutograph camera, Biograph co-founders Herman Casler and Harry Marvin boxed for the camera. Two months later, on 5 August 1895, the first four official films were taken, and this time the sparring was done by Professor Al Leonard and his pupil Bert Hosley. These four films were later exhibited collectively as Sparring Contest, Canastota, N.Y. The American Mutoscope Company was incorporated in December 1895, and the patent for the Mutograph camera was filed on 26 February 1896. The Biograph projector, and the first Mutograph films, were first offered to exhibitors in August 1896, and made their debut in a vaudeville tour in September-October 1896. The Leonard-Hosley fight films were registered for copyright on 18 December 1896. — Walloon 19:28, 6 June 2006 (UTC)

[edit] Further Updates to Kinopanorama Tech Specs.

Measurements of various aspects of the PSO-1960 cine camera were carried out in Melbourne on 1st June, following the delivery of same to The Aranada Group, which have been engaged to convert the camera registration pins from KS 1866 [4740] to BH 1866 [4740] by October, 2006. The specs have since been forwarded to Mr Dan Sherlock in the USA. He is presently in process of updating the technical info, so that changes in the specs may be downloaded to the Kinopanorama website in July. Jslasher--Jslasher 23:46, 11 June 2006 (UTC)

[edit] comparison

would it be possible to get a comparison, somewhat like a resolution based analysis for these formats? --AlexOvShaolin 19:38, 7 January 2007 (UTC)

On what basis? Resolution issues ultimately come down to the film stock type being used, as well as the size and lenses, plus the post-production route. So there's no way to objectively compare resolution on the basis of format itself, aside from some broad generalizations. And even then... Girolamo Savonarola 06:10, 8 January 2007 (UTC)

[edit] Kinetograph cylinder & Silent film standard

Are these formats listed correctly? My suggestions: Kinetograph cylinder> Kinteoscope cylinder, and Silent film standard> Kinetograph (Because Kinetograph used 35mm perforated film). Erkanumut 23:07, 15 July 2007 (UTC)

Well, as far as I know, the Kinetoscope was only used to refer to the viewing machine (hence "scope") and the "authoring" device was therefore called the 'graph. In both cases, their designs evolved over the course of R&D, which changed it from a cylinder to a horizontal strip to a vertical strip. I don't think that there's anything saying that the Kinetograph had to use 35mm film - that's simply what it eventually wound up using. DCGeist might be a good one to ask, as he put a lot of time into the kinetoscope article; I'll give him a buzz. Girolamo Savonarola 23:59, 15 July 2007 (UTC)

I support and have made the change from "Kineotgraph cylinder" to "Kinetoscope cylinder" on two grounds: (a) consistency with the following "Kinetoscope horizontal" and (b) certainty that the term Kinetoscope had been coined by 1889; it is possible, but not certain, that Kinetograph had.

GS is correct that the Kinetograph did not have to use 35mm film--indeed, the 19mm film we describe as "Kinetoscope horizontal" was shot on what was called a Kinetograph. Thus, the existing "silent film standard" is more appropriate than "Kinetograph."—DCGeist 04:57, 17 July 2007 (UTC)
