  3. 3. TM Introducing 7 Key Innovations #FIATIFTADubai2013 Sai Prasad, The future of film scanning
  4. 4. Innovation 1 TDI Sensor • • • • • #FIATIFTADubai2013 TDI – Time Delay and Integration - Advantages – High sensitivity – High speed – High flexibility Scanning Speeds (35mm 4perf) – 15 fps in 4K resolution – 25 fps in 2K resolution About 50 Times More Sensitive – Compared to single line CCD sensor – Lens with small aperture resulting in large focal depth – Easy to set focus – tolerant to film bending Low Power Light Source – LEDs with long life Focus Adjustment While Film Is In Stop Sai Prasad, The future of film scanning
  5. 5. Innovation 2 LED Illumination • • • • • • • #FIATIFTADubai2013 Low maintenance, low operational cost Flashed with line scanning frequency Pulse-width-modulation for light level control Optical color matching Various film stocks are illuminated with different spectral wavelengths (R1, R2, G, B) Cool, durable, (Nitrate film friendly) Diffused in an Integration Sphere for reduced visibility of dust and scratches Sai Prasad, The future of film scanning
  6. 6. Roller Gate Innovation 3 Roller Gate • Precision Roller Gate – Film is running on the roller for ~ 8 frames ensuring best intra-frame steadiness – Best for legacy films – Safe – gentle – clean – quiet – Rollers are the only parts touching the film • Interchangeable 35 and 16mm lens gate assemblies (LGA) • Maximum aperture 25.80 mm / 1.016 inch – Perforation edges visible on both sides • Continuous transport via capstan #FIATIFTADubai2013 Sai Prasad, The future of film scanning
  7. 7. Roller Gate 35 mm Lens Gate Assembly (16 mm optional) 2 Gate Rollers, just the edges of the film touching the free-wheeling gate rollers Capstan No pins No sprockets No skid plate No edges No friction No abrasion No harsh audible noise Page 7 #FIATIFTADubai2013 Sai Prasad, The future of film scanning
  8. 8. Innovation 4 Optical Perforation Detection Optical Perforation Detection • • • • • • • #FIATIFTADubai2013 IR illuminated perforation holes Perforations are sensed by a dedicated line camera Widely independent from film shrinkage Proven algorithms to provide correction vectors Touch-free Pin Registration – Image repositioning with a precision of 1/64 of a 4K pixel (~ 0,1 micron) in the spatial processor For both 16mm and 35mm film System redundancies ensure tolerance to damaged or broken perforations Sai Prasad, The future of film scanning
  9. 9. Innovation 5 Dedicated Processing Dedicated Processing • • • • • • • • #FIATIFTADubai2013 Sub pixel steadiness processing LUTs, (log, de-log, lin, 1/x) all in 16 bit Image scaling, cropping, reformatting Frame buffer Proxy generation for cache supported navigation Scanner calibration Camera link interface to TDI cameras PCI-express interface to work station Sai Prasad, The future of film scanning
  10. 10. Dedicated Processing Innovation 6 – Coming Soon In-built HDR • DFT has invented a technique* that has been developed to increase, by over 3 stops, dynamic range of a filmscan without affecting either the resolution of the scan or the speed of scanning *Patent Applied #FIATIFTADubai2013 Sai Prasad, The future of film scanning
  11. 11. Dedicated Processing Innovation 7 – Coming Soon Wet Gate System • DFT is introducing a wet gate system in-built in the scanner • The system uses an environment friendly process #FIATIFTADubai2013 Sai Prasad, The future of film scanning
  12. 12. Prasad Group Overview Digitization, Restoration, Color Grading, Complete Post • India’s largest integrated post production house • 6 Decades in Global Cinema • Over 15,000 Films Served • 20 Indian National Awards for Best Service • Over 300 Hollywood Classics Restored India USA #FIATIFTADubai2013 UK Germany France Sai Prasad, The future of film scanning
