  1. The new Sony sensor is 4112x3008 so good for UHD resolution as the scanner has to "see" the perforation(s) for registration. There is another Sony 6.5K sensor just becomming available but will not hit 30FPS scan speed, more like 15FPS but really good sensors. Maybe BMD will put the 4.6K CMOS sensor in the Cintel and then it will be ok. You can also get the 5K Scan Station but in single flash mode you will get FPN sometimes (not nearly as bad as the BMD) or run 2-Flash at 15FPS. Lots of good choices in scanners these days and I think it will only get better as new sensors arrive, a buyers market.
  2. I had an Imagica Imager-XEplus which I gave away as it was slow as cold molasses and the Toshiba CCDs in those go bad and the one I had was noisy and could only pass a FPN calibration one out of five times. I would also give away that BlackMagic Cintel as it has tons of FPN issues and the "HDR" means somehow that you have to run the film through twice? So not the elegant multi flash of a Scan Station. The Spirit 2K/4K is the industry workhorse and is a true RGB 16bit scanner which is pretty fast (to DPX) and can be really reliable especially if you have a parts machine. When talking to Steve about getting a Scan Station I would recommend getting the new Sony 4K CMOS sensor instead of the 5K CMOSIS one as they all have low DR and noise issues. The 2-Flash "HDR" on the Scan Station basically overcomes the problems with the 5K sensor so if you do go with that 5K chip I would not run the machine in any other mode than 2-flash. Other than that the Scan Station is a dead reliable workhorse Bayer sensor scanner. They really run like a top day after day.. But LaserGraphics also makes the Director which is true RGB.
  3. We do a fair amount of 4K / 5K 16mm (Super, Standard and Ultra) scans Definitely more detail and not just noise/grain IMO True RGB scans often show more detail and sometimes those are a bit to revealing compared to 4K CFA scanner scans which have less detail. Also there are differences between scans which have more detail but look less sharp and scans which have a bit of sharpening added.
  4. Maybe email Cinelab London they are running the negative for Mr. Bond.
  5. Sorry late to this... I made a battery adapter to use Ryobi 18V Li batteries on my XTRProd. I used a Aaton battery and fabricated up a Ryobi flashlight which mated to the Aaton battery. I put a DC to DC regulator in to clamp the 18V battery down to 16V to feed the camera. I also put a 12V regulator on it and a D-Tap for accessories like a monitor or Micro-Force. I am building one for someone now based on a smaller Milwauke 12V battery.
  6. LTO-5 and LTo-6 drives and media have become much more affordable, interfacing them to a machine can be a trick as can the LTO software, especially on MAC but then you have a good backup with a decent amount of storage for each tape that will be recoverable in five or ten years, possibly more so fewer migration steps to be taken. Optical Discs are everything that Perry said especially the part about not having a drive that works in five or ten years.
  7. Yeah Reversal bath not neg bath then you have Hi Contrast direct duplicate.
  8. There are a couple of ways to make a positive from Tri-X these days, a inter-negative and print which is the "right" way to do it and will retain good sharpness and contrast. 3234 is a fine dupe neg stock and Orwo also has dupe neg stocks. We have also made "Dirty Dupes" as work-prints for customers which are basically printing Tri-X to print stock and then running the print stock as a negative to make a one step positive, this is very contrasty but works as a workprint. Olde Thread
  9. I suppose then LaserGraphics can discontinue the trur RGB Director then... 😉
  10. I usually scan S16mm at 2048x1306 which shows some of the incomming and outgoing frame and allows for enough vertical overscan to fix most slight camera flutter without losing resolution. For "Full" overscan allot of times that is a creative choice to see more of the physicality of the film including the perf(s) and keycode etc. but for sure if there is a stability issue having the extra pixels helps to fix problems without losing resolution in the recorded picture area.
  11. Most of the "New" type scanners use a Color Bayer sensor camera like the JAI Spark 20000 in the Scan Station or the Ex-Kodak 16050 in our Xena and Kinetta. They allow for 2.5K or 5K Overscan but they are color camera systems and as such will have color "made" by math and some color separation issues especially with denser negative. The Spirit 4K or Northlight or Ariiscan or Scannity or Director record each color channel separately (I.E. "True RGB") and some will offer overscan (Director, Xena 10K etc.) and True RGB but they get to be slower and more expensive. The Spirit 4K or Scannity or Arriscan have a more limited overscan ability.
  12. Did you give them a reference? I would not assume so. If they did the DPX frames should go right into DaVinci and match up without any changes to the EDL or XML you created in the editor.
  13. Did the scanning facility match the timecode of your original dailies scan?
  14. Film is magic! I have personally shot film and developed it months, sometimes many months after the shoot. Yes film stocks do accumulate base fog but even fast modern stocks do take years to do so. I shot some Plus-X negative 16mm for a music video last fall which had an expiration date of 1966 and it looks fantastic. YMMV
