There are two, maybe three labs in the US which can and would possibly do this, and have the optical printer to do it with.

I am kinda excited to see what comes of 100D Ekta up printed to 2254 Vision3 IN stock which is most commonly used for Arrilaser recrdings and I bet has allot more range than the older IN stocks they used for Texas Chainsaw.

I am actually working on a project right now that is doing the exact workflow that TX Chainsaw did. They shot 16mm color reversal and up shot it on and optical printer to an Internegative and then went on to make prints from that IN. The job we are doing tests for now is shot on Ultra 16mm Ektachrome 100D and I am setting up to up shoot it on our Producers ACME optical printer to 35mm 2254 IN stock. As far as printing lights go that is a bit of test and see how the stock and exposures resolve on the IN stock to print.

We are doing allot of digital to 16mm recording and I have three recordings I am doing right now which are for recording to elements to make prints with sound. For 35mm we can record to IN on the Arrilaser and make a print with an optical track but that is pretty expensive, I am looking into doing direct to 35mm prints.

Cineon LOG is a kind of lossless compression designed by Kodak to follow the characteristic curve of how negative film works, so the density range could be put into 10 bits. All digital sensors are linear response and early Cineon and Quantel scanners used Kodak tri-linear (RGB LIne) CCDs which were 12bit or 14bit linear, the Arriscan is a 14bit ALEV sensor and 2-flash gets it to 16bit precision. So all LOG curve schemes have followed on from the Cineon LOG designed by kodak in the late 1980's There is still calibrating the scanner to the film base and both exposure and lab variations and I think there is no way to just add technical and look LUTs to get a perfect image without also doing some base grading.

I did that to one of my Arri 2B cords too!

16bit DPX is linear not LOG.

The linescan issue in the Spirit is a temporal scan issue not a horizontal one. The Spirit scans the line x samples as the film moves past the aperture and "builds" the picture in the framestore in real time, the speed is governed by the encoder on the sprocket which is 4-800 lines per revolution and does not feed back into the frame store. So when there is frame instability like on a splice the velocity of the lines scanned jumps and you get the issues. In the later version of the Spirit 4K and Scannity there is some feedback to compensate for this. As for new sound scanning. The 8000 line / rev optical encoder used in these newer scanners allows for very detailed film velocity information to be mathematically combined with the horizintal picture scan info or (on the Xena) analog sound capture to create a audio signal that should be very accurate in pitch / stability.This method allows for the info to be processed for temporal variations in film velocity in a very high resolution and not just spit out to a framestore. The LG SS Optical sound reader is just doing a more detailed AEO like sound decoding, I am actually not sure it is a line scan as they may be using a area scan sensor to scan the sound areas Perry would know more about that. We use the built in AEO Light audio on the two Scan Station machines I have and it also works fantastically well, Arri is using AEO in the Arriscan XT now. I have not really had any pitch issues on any of the 8mm 16mm or 35mm films with sound we have scanned from either the Scan Station or Xena scanners.

Just use a 12v voltage regulator inline from the V-Lock plate to the EBM power plug.

oh boy. Real new scanners do not rely on the crystal locked frame rate of the film to correlate the sound like legacy telecine. So if you look at how sound heads are setup on the LG or Xena or DFT/Sondor machines there is a very high res optical encoder drum at the sound reader, this drum will typically have a 8,000 line/rotation encoder that drives sampling the magnetic or optical sound. This frees the scanner to run at any scan frame rate and have the sound be resolved to the resultant required playback speed. The LG machines use a line scan to basically do a high res picture of the optical track and decode it in the same manor that AEO Light works, but with higher accuracy as it has a known number of hundreds of thousands or millions of film velocity samples per second. The Xena uses a 8000 line encoder and a A/D in a National Instruments high res digitizer card. Not sure how the Sondor on the Scannity or Polar DFT machines works but I think it is similar to the LG system. So there is really no actual technical way for wow or flutter to be introduced on these new scanners because the physical scanning speed is irrelevant to the resulting playback speed of the sound or picture. The playback sound speed is done in math with vastly more sampling in time and visual representation per film frame than are necessary or have ever been available before.

My Scan Station SSP (perzonalz) with HDR has the same build moniker (lg_7_3_349_1221) as all the Scan Stations. The Archivist has the build as sa_7_3_289_5531 not lg I probably need to update them soon to the latest builds with DNx For comparison: The Arriscan update requires cloning the CERN Scientifc Linux drive from the Sun workstation and sending it to Arri and then they send it back and remote in to finish the update.

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.

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?

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.

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?

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.

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.

This is a clearly uninformed statement. Kodak film products and photo chemistry are excellent in quality and in plentiful supply, labs are busy.

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.

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.

We did the tests to show. The client. Who we did the tests for. And who paid for them.

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.

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.

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.

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...
