Any pictures?

I have some CP16 magazines in poor condition, but a bit of cleaning and servicing will revive them.

The most commonly associated phrase with the film industry is "lights, camera, action", and yet you will never hear it on any movie set. For one, it does not mention sound at all. And two, lights are continuously on well before cameras roll, and do not need to be called. I imagine, however, that if you are using carbon arc lights, it would indeed make sense to have a dedicated call to strike them, as they burn hot and consume rods. What I haven't found yet is actual evidence or documentation of a "lights" call on film sets from the silent era. Does anyone know if silent film sets really had such a verbal sequence to strike the lights before cameras rolled?

K65K: 65mm camera 1 to 800 fps
Geffen Avraham replied to Luca Bonicalza's topic in 65mm / IMAX / Iwerks
I also do conversions of this camera and am open to selling one, but it would be without Luca's patented lens system. That said, it can work with other large format lenses. -

I'm pretty sure the Eclair HD-144 kit used a custom-CNC'd TS flange. This is trivial to get made nowadays in China. I have a VP-S16 ACL and can post pictures. I can also send it, along with my standard 16 ACL, to someone like Richard Bennett if they are interested in taking apart the movement and reverse engineering the s16 conversion parts.

Film is back BUT cameras are dying
Geffen Avraham replied to Boris Kalaidjiev's topic in General Discussion
I really want to make it work with a 1000ft Arricam mag, which has built-in motors. For that, I need to analyze the pinout of the Arrimag connection. If anyone here has access to an Arricam, I would be very happy to learn more. -
Film is back BUT cameras are dying
Geffen Avraham replied to Boris Kalaidjiev's topic in General Discussion
The first one I build won’t be quiet, it will be the lightest and smallest vista ever made the old Mitchell butterflies were about 17lbs with 400ft mag, but they were non reflex and the reflex conversion added another 5-10 lbs I am targeting under 15lbs with 400ft mag and reflex. There will be no viewfinder or ground glass. A pellicle will split 1/10th of the light to a BHG1 or similar full frame digital camera. An OLED SDI EVF will be used. -

Doesn't Kodak have new coating factories in China now? As for why Vista, because regular 35mm cameras are already abundant (I got my Konvas for $350), while 65mm is hard to process, only Fotokem does it in the US. For 35mm there are a dozen different houses across America and more worldwide. So Vista makes sense for a new LF film camera. Geoff Williamson's high-speed VistaVision can have its precise movement stroke and depth adjusted by changing the relative angles of the eccentrics. In his version they were linked by a drive pulley, in mine they will be separate digitally linked servos. The camera will be able to dynamically balance and optimize the movement in real time with multiple degrees of freedom. Manufacturing tolerances can to some extent be compensated for in this way. -

I am working, very slowly but surely, on an open-source VistaVision camera. It's designed to be maintainable forever and manufacturable via Chinese machine shops like JLC. I suspect by the time I have it working, the current VistaVision craze might have died out... But who knows... 70mm was dormant from 1996 until 2012, when PTA and Nolan revived it and it's still going strong. -
@John Krawlzik, do you still have Paul's notes on this? Would you be willing to share them? The process of converting an ACL to S16 is very close to being lost, and I would like to preserve it. In theory, any tech should be able to do it with the right custom parts. Luckily, precision CNC parts are very cheap to have made in China these days, so if we can put together a list of components, drawings, and an installation guide, we can preserve an open-source conversion process than any tech will be able to do for decades to come.

Battery for 16mm Eclair ACL2
Geffen Avraham replied to Luca Rocchini's topic in Accessories (Deprecated SubForum)
Hello! I can help! I sell cheeseplates that mount to the side of an ACL. I'd recommend you get the 1/4" version of the cheeseplate and a SmallRig Mini V-lock plate Then use a SmallRig VB50 battery - it has a 12V regulated barrel output. A barrel to XLR connector will get your camera running! This will work for all normal framerates, but not for 75fps high speed. If you need high-speed, we are developing a new version of our cheeseplate with an integrated power converter, it will be available in a few months. Best wishes!

Steve, did you ever get to work with Doug Trumbull? My dream as a child was to become his apprentice. But sadly, I never got to meet the man. Before he passed, I know he was planning to direct an epic movie of his own on the scale of 2001. I wonder what happened to it, and if his plans for it still exist or are remembered somewhere.
