  1. We are running a high profile spot for Hermes today that was shot on 16mm 500t rated as 320t without an 85 - this was on the cans that came in today. I assume they used some ND will see when it goes on the Arriscan..
  2. There are two ways to really do this... 1. A sound speed crystal locked capstan that will give consistent sync results from analog capture with no wow or flutter. This is how it has been done with telecine and resolvers like the MagnaTech for years. 1. A digitizer like a Nat Instruments card that treats the incoming audio as data and then a servo capstan with a high resolution quadrature encoder that the scanner system can correlate pulses per frame to the incoming audio data to keep them in sync and matched to the proper resultant frame rate at whatever scan speed the scanner is running at. Xena Scan Station and Kinetta do the latter I believe, so they can scan and digitize audio at any scan frame rate.
  3. I think you meant to say it was the only way before we had digital scanners and tools. Liquid gate is like any other tool it has it's applications benefits and drawbacks. And yes it only fixes base scratches.
  4. Last year we developed some EXR ECN film for a museum that was shot in 83-84 and most of it turned out remarkably well. We also see older 50D semi regularly at the lab and it holds up ok when shot with the age in mind. Expired film stocks can and do look great and you can get a look from them that you otherwise would not be able to, but they will have more grain and some anomalies. For example almost all the Fuji we still see come in has issues with the Rem-Jet backing staying on the film to some degree.
  5. Perc is pumped into the chamber with some and vacuumed out with others both before and after the gate chamber. The liquid is continuously circulated by the wet gate support system. Similar to a ACME or Oxberry liquid gate and the chamber has enough height to keep the optical glass out of the imaging plane. Can run at 5-7 fps with enough time for the little amount of perc to dry before the capstan with some active air venting / vacuum.
  6. $1k/gal stuff I have seen and the containers, 3M makes it. Like HFE for the Lipsner cleaners but different viscosity and RI.
  7. Perc with a vent hood. otherwise your looking at some of the extremely expensive “engineered fluids” that Arri and DFT use.
  8. There was a sponge / roller based wet gate for the Rank/Cintel telecine which used Tric then Perc. So Perc should work, not sure if you can use that in Cali. Here is a Xena 16mm liquid gate:
  9. I believe the usual cost of support on just about any capital machine is about 10% of the new cost annually, so probably $20k for a full Scan Station. Cinelab has processed and scanned 50,000ft of various film stocks in a day before. Not every day. 8-10,000ft a day when busy is pretty easy to do but it will hardly yield CitationX and Konegsegg money after overhead and all.
  10. That is a Cintel DSX or C-Reality scanner, a late model flying spot machine capable of 2K or 4K scans.
  11. I use this lens on the 4K Xena we do all of our 8mm work on it is quite good and less costly by far than the Macro-Varon.. https://www.closeuphotography.com/makro-symmar-80-test
  12. This is the one, or a printing Nikkor 95mm or 105mm. https://www.fotozones.com/live/index.php?/articles/tech/the-schneider-kreuznach-macro-varon-85mm-f45-r247/
  13. The old adage applies... Good, Fast, Cheap... pick any two... I would say that most likely the ArriscanXT probably is what you want if you are looking for the best technical picture quality in a scan. True RGB scanning with a monochrome sensor and in 2-flash it is real 16 bit precision. 6K to 4K or 2K oversampling for Mr Nyquist. The ALEV sensor that Arri uses / has manufactured is something that Arri has allot more technical and manufacturing control over than a company using an off the shelf machine vision camera and the ALEV was designed from the get go to be a cinema sensor. Plus a full immersion liquid gate system is on offer from Arri. Nobody ever got fired for using an Arri camera or scanner their color science is known to be the best available. If you are a smaller archive not working on new studio film or high end restoration you probably cannot afford to scan on the ArriXT and so there are any number of good solutions with various levels of compromise. The 6.5k Scan Station (or Xena) will make you 2K or 4K scans which are probably reasonably close to the Arri when run in 6.5K mode with 2-flash that yields 14bit precision from the 12bit Sony sensor. There is also the advantage of 6K to 4K (or 2K) over-sampled rez scans. I think that puts the 6.5K Scan Station at 7.5FPS when run that way and it can scan direct to ProRes4444 saving a step converting DPX to ProRes. 4K scans in single flash 12-bit from Scan Station Xena Kinetta or HDS+ or any number of scanners using the off the shelf Sony Pregius 4K and 6.5K sensors will also yield excellent results which would have been unobtainable just five years ago for the price and speed. Even the RetroScan can make pretty good scans right out of the box and if you swap out the provided 2K sensor and mod it with a camera like the 4K Pregius (4112x3008 12bit) you can make some really good scans on the cheap that will just probably need allot more work in post to stabilize. The best scanner is the one that gets the job done to the required specs in the time frame and budget allowed for.
  14. I just acquired an Arriscan last week so that means i have SIX effin MP scanners in my shop now..... 1. Spirit 2K (HD) 2007 2. Spirit 2K/4K Data 2008 3. LG Scan Station "personal" 4. Arriscan 5. Xena 4K (s8) 6. Xena 6.5K 8/16/35 I was reading the manual for the Arriscan on the train to NYC today.. a three hour ride... and there is at least three hours of reading there... What a great machine and it does some things which are truly great like changing calibrations automatically by reading the keycode info. I have spent the last 9 or 10 years helping Co-Develop the Xena scanner with Rennie at DCS in LA and believe me I have felt some pain in that development experience. I began a decade ago because I needed high quality scanning for the lab and used scanners were very very expensive. So I built a Xena 1.0 based on a Oxberry pin registered transport with an Atmel Camilia camera doing sequential RGB and IR scanning at about 0.7FPS. The Xena is now a very mature and competent scanning system with some really advanced features loke optical pin registration and excellent under the hood control of allot of film scanning and machine parameters. Xena can be a stand alone built machine or retrofitted into some of the truly excellent legacy scanning chassis like the Cintel URSA. It is very reliable and is quite a bit more technical to use that the Scan Station but it is a Win10 based scanner with a pretty understandable GUI. So if you want a high quality scanner and are technical there is a option that meets cost constraints it advanced and very high quality, it is not the slowest nor the fastest of scanners. The last generation of the Spirit DataCine kind of speaks for itself, it was capable of realtime 2K and 7fps 4K in 2005 or so. It is still an excellent true RGB scanner with great speed. It is loud and hungry and not suitable for home use these cost between $1.2M and $2.2M new. The LaserGraphics Scan Station "personal" has been a bit of a mixed bag for us, it is very fast and extremely reliable, I hove found it has very few bugs and occasionally it gets funny but just requires a software restart to get back to normal. The GUI is by far the simplest and easiest of any MP scanner and you don't have to know Linux (Like RedHat for the Arri or SUSE for the Spirit) and anyone can easily run it effectively IMO. Unfortunately it is sort of stuck with not the greatest of cameras (the cmosis CMV50000) so it can show fixed pattern noise on some occasions, like the BMD Cintel does. I am a it disappointed that LG did not see it as a product that they liked nor do they seem to want to improve it. I think they could have had a really good sales experience with it if they had added the 2-flash 'hdr' in software which fixes the problems with the camera mostly. I think they should have called it the Scan Station Dailies and had a keycode reader standard and aimed it at all of us labs. Our machine reliably works almost every day for a range of things from scanning prints to student work. From what I can tell the full 6.5K Scan Station is a very mature product that is very very fast (LG's hallmark has always been speed in scanning) makes very good high res scans and it by all accounts very reliable. I see some crit about the cost of the machine but a base ArriscanXT is more than 2X the price and a Scannity is more than 4X the price so it is a relative bargain from a business perspective. It seems the Scan Station has a niche in doing allot of archival scans where speed is cost and that it is a great tool for that work. Shows like Star Wars, Succession, Euphoria etc. typically are done as new on Scannity but that is large post house workflow and costs are much higher than a small shop scanning allot of archival jobs which are much more conscious of cost. Arri and DFT have large engineering staff and charge a ton for support and big post houses require that because big shows have deadlines. I think LG is a smaller company and probably have to figure out what support fires to out out and as such have to prioritize who get what, and with most things capital the paying squeeky wheel usually gets the grease first. YMMV.
  15. You could do that on an optical printer like a JK but you would be looking at ding four passes onto the 16mm, one for each S8 quadrant. It would take some time to setup and impliment and any error would put you back to step one on it. Or you could have a compnay like mine do a filmout to 16mm of the sequence.
  16. I accidentally got included on a email thread about the GE scanner by a similarly named lab in London..... nothing nice was being said about this machine in that thread and they were trying to do 65mm dailies with it....
  17. The DSX is a good candidate to turn into a Xena scanner. www.digitalcinemasystems.net Rennie has control over all the transport systems and is doing a refit to one now.
  18. It took me all of ten minutes to learn and start using the scan station, Steve Klenk came to do training but honestly with a few caveats the machine does not really need much of a manual to use it. You should see the 285 page manual for the Arriscan and you also better know linux and be decent at math for that machine. Similar to our DFT Spirit 2K/4K Data machine which runs SUSE 10 for the Bones or SUSE11 for the PhantomII control software. It took me a week to get the PhantomII software running on a Z840 with SUSE11 configs and drivers etc etc. I have the original sales receipt for our Arriscan it was $580,200.00 in 2007 and the DFT Spirit 4K was $1.75M in 2008 So "they" have made a low cost scanner and it has sold like hotcakes, it is called the Scan Station.
  19. Basically a tri-linear 4K CCD machine i.e. a not as good version of the Spirit 4K or Scannity. Evidently not the most reliable of scanners either.
  20. Actual full immersion liquid gates do not "drip" they have a chamber that is completely filled with liquid and the liquid is managed with pumps that push it through the chamber / gate and constantly cycle the liquid through filters. There is a vacuum system that removes the fluid and air knives that dry the film before it is taken up.
