Hey David, Yes, it is regular camera negative stock from Kodak. We were initially wondering if the problem related to the short end stock being mislabelled. But the same thing is clearly happening with new 5222 Kodak stock. Peter

Hey guys. I originally began a thread on the issue of having problems with running Black and White 35mm film through my Arri IIC (it's, I believe, an Arri IIC/B) http://www.cinematography.com/forum2004/in...?showtopic=6689 In a nutshell, there seemed to be a problem where B&W film, which we had obtained through a short ends distributor, didn't run through the camera. The film would intermittently be torn between perfs, and the film would lose its loop in the camera. The roll we were running through was a 400 foot short end, incidentally. a short colour 35mm roll (about 200 feet long) ran through the camera no problem. When we physically lined up the B & W short end with a length of colour film, there seemed to be a bit of perforation drift, by the equivalent of a full perforation over the course of a 6 foot strip of film. It seems, from the answers I received, that this shouldn't be the case. In any case, we wondered if that had something to do with the film not running properly. UPDATE: We bought a 400 foot new roll of B & W film, directly from Kodak. This film clearly does match up, perforation-wise, with our colour 35mm film. But, when we run through either the full B&W roll, or a shorter one (100-200 foot roll), the same thing happens. Perfs get torn, the film loses its loop. Yet when we go back to the colour 35mm stuff (which lines up exactly, same perfs, everything, same amount of feed footage in the mag) it runs fine. Arrghh... what gives? Peter

Hi John, If I did get Kodak B &W (5222) and Kodak Colour (5245) 35mm films from a short ends distributor, and both would seem to have originated from earlier this year, would it be possible that the perforations of one, relative to the other, drift by the equivalent of one full perforation over the course of about 6 feet of film? And again, when I run each roll through - the colour one works, the B & W clearly tears and loses its loop, then back to the colour one, and it works, and then back to the B & W one, and it tears and loses its loop - does this seem possible? I know that on newer cameras than the Arri IIC there are more sophisticated pitch control adjustments that can be made, which are done to make the camera quieter - but should any type of stock completely not run through the camera? Peter

Hi guys, Does Kodak 35mm black and white motion picture negative film have a different perforation pitch from Kodak 35mm colour motion picture negative film? I recently bought some of each from a short ends distributor, and the colour runs through my camera (an Arri IIC) fine, while the B&W perforations seem to continuously tear, and the film loses its correct size loop within the camera. The two films would seem to both be new, originating from approximately early this year. The perforations drift by the equivalent of one full perforation over the course of about 6 feet of film (when you hold a strip of the colour against a strip of B &W) Does anyone have any suggestions / explanations? Peter

Hello, They did indicate that the larger 18 X 24 Gray Card was still available. The 9 X 12 one, and various colour strips they said weren't available on back order, and were officially discontinued (in "continental North America", I believe he said), and there was no substitute product planned, at least currently. Peter

Hi there, I was recently inquiring with Kodak about their various gray scales and color charts, and it seems like several of them have been discontinued (such as the 9" X 12" Gray Card Plus, or various colour patch charts (such as Cat. #s 152 7654 or 152 7662). Does anyone know why? Is there an intention to eventually replace these, or if not, is there a comparable product made by another company? Peter
