A motion picture film scanner is a device used in digital filmmaking to scan original film for storage as high-resolution digital image files.
- A Motion Picture Film Scanner scans original film negative or positive print or reversal/IP. Units may scan gauges from 8mm to 70mm... (8mm, Super 8mm, 9.5mm, 16mm, Super 16mm, 35mm, super 35mm, 65mm and 70mm) with a very high resolution scanning of 2K or 4K film resolutions... (approx. 2K= 2048x1536 pixels and 4K= 4096x3072 pixels).
The scanner scans the film frames into a series of data image files (DPX or TIF),using high-end Data storage devices. These systems takes a lot of Storage area network-SAN disk space. The files can be played back one after each other on high-end workstation Non-linear editing system-NLE or a virtual telecine systems. The Playback is at the normal rate of 24 frame per second (original projection frame rate: 25, 30 or other). Each year Hard Disks get lager and able to hold hours of movies on Tera Byte systems. The challenge is to archive this massive amount of data on to Data storage devices. The footage is edited and composited-FX on work stations then mastered back on film, see film out. The film may also be projected directly on HDTV-high definition Digital Projector in the theater. The film may be converted to SDTV (NTSC or PAL).
Types of film scanners
- Single frame intermittent pull down, also called pin-reg scanning.
- Continuous motion scanning (See Telecine anddigital intermediate)
