  1. I would suggest 3D printing a cover with a 4-Pin XLR that could be fitted over the existing Arri motor terminals and cutting them down to flush with the motor casing and then soldering on wires to go from the two terminals to the XLR.
  2. LaserGraphics has sold so many Scan Station scanners I half expect to see my local Pub or 7/11 offering MP scans sometime this year. Everyone has one, I personally have two. They are just so reliable and in constant use by the labs, post shops schools and archives and they cost relatively so much less than a big iron machine that it is not likely that many used Scan Station machines will show up on the used market. Anyone want to buy a nice Spirit 4k?
  3. The Hydra looks really nice but I could build that in conjunction with my friends with CnC machine shops etc for what I imagine would be allot less than their asking price. The Lipsner XL1100 can pretty easily be made to run 8mm and lots of labs do that, the XL1100 has some "prototype" like engineering but again with some mods and an updated PLC it can be made to basically operate like the Hydra and even could be modded to have a variable gap etc. Got me thinking about mine and mods now... The newer Lipsner 8200 HFE ultrasonics have a PLC and arguably do a better cleaning job than any buffer only type cleaner and they can be run with the newer solvents. We had an early San Labs cleaner and it was pretty bad, the newer Prista cleaner is better but also not great but a good basic and inexpensive to buy platform to build off of IMO.
  4. Uh the films made the studios billions of dollars in profits why would they not green light more 65/15p films when they clearly make huge returns and audiences love them?
  5. You would have to do some experiments r.e. running this as a positive, the Kodak manual for Reversal has a light for re-exposure between the clearing bath and second developer so that would be ideal to run as reversal with full re-exposure. I think that would overcome any base issues for reversal development. As for the very thin acetate I am not sure exactly why it is that way. I think the issue will be running it with camera stability and keeping it jam free. We ran a notorious 35mm feature in 2017 which was hundreds of thousands of feet of 5222 and the camera department / DP wanted to shoot 3-perf Arrcam cameras but ended up shooting 4-perf just because it was allot more steady and compatible with the Arricam pin-registerd movement. I would think an Arri 2C would not have issues with the thin acetate base.
  6. That seems like a nice machine and kind of similar to but updated XL1100 buffer style cleaner. I have had two XL1100 Lipsners and they have been reliable aside from some of the questionable engineering in a few areas, things which can be remedied with some work. Most places run an Ultrasonic cleaner for all negative scans and there is a new HFE replacement which is less costly.
  7. This is a clearly uninformed statement. Kodak film products and photo chemistry are excellent in quality and in plentiful supply, labs are busy.
  8. Well this has nothing to do with digital recording to film. As for "plug and play" the BMD Cintel is very sub par, the LaserGraphics Scan Station beats it in every possible way. Blackmagic seems to have no intention to replace the noisy sensor in the BMD Cintel and absolutely definitely will never make that thing a RGB scanner. If you want true RGB HDR scans be prepared to pay Arri / DFT / LaserGraphics a half a million or more. You could have a Oxberry pin registered Xena for about $55K with a new 6.5K sensor.
  9. I think there is some misinformation about early scanning in this thread. None of the telecine machines even the very old ones had "sharpening" (Coring and Aperture correction) which was not able to be turned off. Even the old Bosch Quadra and other early CCD telecine had these controls, the colorists tended to ride them to taste. The original SDC2000 Spirit ( one 1920 mono line and three 960 rgb lines) which was the first real "Data-Cine" used on "Brother Where Art Thou" with the HIPPI data and Pogle had the ability to make quasi 2K scans that looked fairly good when setup correctly. Same with the Cintel / ITK Millenium and DSX flying spot 2K 4K Data-Cine machines. The Spirit SDC2000/2001 the Millenium and DSX and especially the later Spirit 2K / 4K machines never had problems scanning prints or other positives like Kodachrome or Ektachrome, the need for a low con print was really a standard def issue not for any of the HD telecine. People would make a Low Con print to give more room in grading in the early HD days but it became a legacy practice by 2005. The Spirit 4K was the fastest scanner for 4k and 2K until after 2010 and the fastest 4K / 2K true RGB scanner until the Scannity replaced it, it ran 2K in real time and 4K at 7.5fps. There were no real 2K + res Bayer Mask scanners till well into the 2010's the first ones were Kodak 2K and 3.3K CCDs used in the Scan Station / Kinetta / Xena etc. scanners with some single tap and some with various levels of tap balance issues. None of these machines were major market scanners. The Jurassic Park scans done on a Kodak Cineon 4K Tri-Linear CCD scanner hold up well today 30yrs later, it just took 4 minutes per frame to scan them to some beast of a SGI machine.Quantel had the Domino system which had similar performance both based on the Oxberry shuttle. Great data scanning has just become available to everyone, the Cineon technical specification that Kodak built and which became the basis for all data scanning was and is a very high technical spec which has worked for thirty years, this is separate from and concurrent with scanning film to video for broadcast which is low DR Rec709 and what Telecine was built for.
  10. We did the tests to show. The client. Who we did the tests for. And who paid for them.
  11. Any B&W stock can potentially be developed as Reversal but you would have to hand tank it and that will be allot of work, I do not know of any B&W reversal processing labs (Like us at Cinelab) who have a 35mm capable processor setup for doing reversal. This is simply because Tri-X Fomapan etc. are only really available as 8mm or 16mm. As for the thin acetate base I am not sure what to say about that it should not be that much of a problem in a still camera but might be an issue in a motion picture camera especially a pin registered one like an Arricam or Panaflex. I would think an Arri 2C or Camflex or similar camera without pin reg it would transport fine.
  12. Maybe not related but still there are only a few ways to make B&W film stock so definitely cousins. I would rate it at 20iso and not shoot in low light.
  13. I would not say the Arrilaser is a bad design it is just the best tech and the parts available in the late 1990's They do work and make excellent recordings even with Windows NT and odd parts. The scanners end up having bearing issues and then if they don't start they are hard to (or impossible to??) fix. I have two.
  14. Yeah them CRTs got to be looking pretty crisped by now. Kind of difficult to keep them and even the Arrilaser machines running. Sony just came out with a new 4K x 3.5K Micro OLED I am trying to get my hands one one when they release them, of course they want to know how much volume you will be selling and that is not allot... There is a French company that also does Micro OLEDs so maybe one of these panels with a piezo shift or the JVC LcOS with Piezo shift for 8k recording...
  15. Old first gen MP film scanners used tri-linear CCDs that were 3K / 4K and then 5.7K this was true RGB scanning where there are three lines of pixels and they were R, G and B with color filters over each part of the line, they were typically made by Kodak's CCD division. This was usually in conjunction with a pin registered Oxberry transport and it took 20-30sec (or much more) to scan each frame. This is "Jurassic Park" era where only some shots would be scanned for VFX to then be recorded out and inserted in a negative cut. So 35mm and even 16mm was able to be scanned on Cineon scanners in the 1990's to 4K and that worked pretty well. Later scanners like the Northlight-2 got the 8K (or 9K?) Kodak Tri-Linear sensor and could to 2X over sampling or actual 8K scans. The Later generation Spirit scanners (2003-2009) had three 4K Kodak CCDs with dichroic color filters for real time 2K and 7fps 4K true RGB scanning. These scans still look really great today. The Arriscan has a 3K ALEV sensor and does a piezo shift to make 6K true RGB and true HDR down sampled to 4k. None of the above was in any way available to the regular public to fuss over these machines were in big iron post with engineering staff and got fussed over by the big guys. CFA scanners like the Scan Station only really got going fairly recently and the first gen Scan Station used a 2K or 3K Kodak CCD in quad tap mode and it had allot of issues with showing the tap balance so there would be obvious quadrants, they went for speed over quality as allot of places wanted the speed. Things only really got to somewhat modern when CMOSIS introduced a 5K 30fps capable Cmos sensor used in the Scan Station and the GPUs got fast enough to process that, this is about five years ago. Now there are some new sensors like the Sony 6.5k used in the Scan Station (color) and Director (Mono sequential RGB) for up to 13K scans and DFT has put the new G_Pixel 9.4x7K mono sensor in their Polar scanner and the Sony 14K mono sensor in their Oxscan for 65/70 I don't really think there are any definitive public tests on "what res" is film as it is an organic medium being pushed into a grid pattern. In general I think Nyquist over sampling at 2X the intended res is what should be the goal and true RGB still beats CFA in detail and color fidelity and separation, I think both 16mm and 35mm really benefit from a 4K scan, negatives more so than prints. As the sensors get better and higher res capturing the whole film image which is made of clouds and grains at reasonably higher res shows an improvement in the final results and with that resolution comes the other horsemen of the emulsion full density range and color separation especially in over exposed negatives. I think everyone who does this work as a job sees the benefits of scanning 16mm and even 8mm at 4K and it is trivial to do now in fast color scanners and even true RGB scanners, I can see 35mm having some benefits from 8K scans too as they become more easily available. Ultimately is this a pixel peeping tech obsession or realistic best practice for the intended delivery format, most likely to be compressed online or UHD and HD video and rarely (for most) a return to 35mm prints or finely finished 4K DCI distro.
  16. How old is it? I used some Kodak Plus-X 16mm negative in 2019 that had expired in 1962 and it came out great, shot in full daylight and I rated it as 20iso.
  17. We are doing some tests for a film and ran some push +3 and +4 for 7222 but I cannot show that, it looks ok but obviously grainy which is what they wanted. We regularly run 500t to +2 and have done +3 but going beyond +3 is a bit tricky because you really have to slow the processor down allot and possibly add heat to the developer which can have unintended color shifts which have to be compensated for with a different repo on the developer chems.
  18. You could / they may just record the part of the element you need on the stock and then print the rest, would require a traveling matte or some such rig in printing on an optical printer. Instead of just recording the whole frame. FotoKem would be the only lab with Celco Fury 65/15P recorders I would think. Some of the new micro-oled panels look promising maybe with a piezo stage and multi level exposure.
  19. Ah yes the Disastor "test" which seemed like a make work project for some academics who don't actually use or know anything about film. So this is Part II the more Disatoriniinnning... now with their own scan scan machine
  20. Vague at best. "Multi Spectral" i.e. sequential RGB? that is "multi spectral" as in red green and blue. The example on their web site I actually prefer the look of the "other" system and think it will grade to finish better than their example.
  21. The Scan Station "personal" can be upgraded to the latest software with 2-Flash HDR and that makes it a decent 12-bit scanner and the noise from the older CMOSIS camera is mostly gone. So for $20-25K used plus about $15K you can have a updated 35/16 Scan Station that works really well. Nobody complained about the noise from that camera more than Moi. GPU "pin registration" using machine vision is really excellent almost all of the time I think the LG or Xena edges out my Arriscan a bit on 16mm but is about the same on 35mm. The Arriscan definitely has superior color fidelity and color channel separation and overall detail compared to any of the bayer mask based scanners HDR or not. I am sure that is why LG makes the Director 13K ( which is a Monochrome Sony 6.5K and a pizeo stage I assume ) RGB scans for the Pic quality win and speed loss. There are a few ways to clean film I have a Lipsner XL1100 alcohol cleaner which is Ok for basic dirt / dust A Lipsner 8200 Ultrasonic which really works and for really tough stuff the option of rewashing the film in a film processor can kill all the mold and help heal emulsion problems while releasing allot of the really hard to get out dirt from the emulsion. There are new cheaper fluids for cleaning and full immersion liquid gate scanning that are environmentally ok and easily available now. I think the cameras keep getting better, as far as I can tell the 5.4K Sony in the Archivist is one gen newer than the 6.5K Sony and it looks excellent has great dynamic range and extremely low noise. The 6.5 Sony is also great but has some odd color stuff and allot of color channel cross talk when I went through allot of setup on the Xena, this is all done by LG as a turnkey scanner product. Most TV and Movies you see get scanned true RGB at Co3 or Postworks or FotoKem on the DFT Scannity or Arriscan. DFT has introduced the new Polar scanner using the G-Pixel 9.4K x 7K sensor so that can make true 8K RGB HDR scans. FotoKem and Cinelab London have the DFT Oxscan 14K 65mm / 70mm RGB HDR scanner for things which are big. I could see 4K or 8K continuous motion true RGB sequential HDR scans using X-Y GPU Machine vision registration shortly and the LG Director and DFT Polar might already be doing this, massive bandwidth from the camera and allot of GPU making it possible.
  22. I would go for it, I think any B&W will hold up very well if it is in relatively ok storage conditions. I personally got a few rolls of the 1962 Plus-X because they were just a little shrunk for the purpose someone had them for but they went through my Aaton XTRprod just fine.
  23. B&W film stocks last exceptionally well, I used a roll of Plus-X Negative for a music video a few years ago that had expired in 1962! Color turned to B&W never really matches the contrast of real B&W IMO. There are a number of options for current B&W stocks and how to process them, 7266 runs nicely as a negative and I still really like 7222 processed properly, we have dome some overexpose and pull and some underexpose and push processing for various clients that worked well for their purposes. Here is the MV with the Plus-X from 1962:
  24. The general rule is to overexpose about a stop per decade when using expired film. I think that rating it at 100iso and processing normally achives the same thing as 200iso and a push +1 and may even produce a bit nicer result.
