Digital Intermediate

WFDiF uses the Digital Intermediate technology that combines the conventional film method with modern computer technologies. We use it in digitalisation of analogue image, its digital processing and correction, and then play back the analogue content on a film stock or a TV screen.

WFDiF’s Film Laboratory has the equipment necessary to use the Digital Intermediate process:

Colour Correction – Discreet Lustre

The Discreet Lustre system that we are equipped with enables colour correction on materials recorded as sequences of graphic files up to 4K resolution. The unique precision (32bits/channel) as well as available tools enable to complete not only sophisticated colour visions, but also visualise additional effects on a calibrated 24" Sony HD screen or an HD-JVC projector. Another distinguishing feature (not available in equipment-based solutions) includes animated masks made of curves. .This enables corrections of any area together with simultaneous tracking of their location. Lustre is also equipped with a DVS HD/SD card that allows to import video images directly to the system. Importantly, we closely cooperate with ARRI, (producer of the ARRILASER 35 mm recorded) in respect of colour calibration of the whole Digital Intermediate process, which results, among others, in availability of 2-D and 3-D LUT for pre-visualisation as well as image writing. In the configuration available in WFDiF, the source material may include sequences of files originating from the following sources:
- ARRISCAN scanner (DPX logarithmic files in full film resolution of 2K or 4K)
- High Definition video (we have a Sony HDW-F500 VCR)
- standard video signal recorded on any storage device (we have VCRS that support the following standards: DigitalBetacam, Betacam SP, IMX, Betacam SX, DVCam, miniDV)
- computer animation
- any images of other sources, recorded in the format of popular graphic files.

Image writing onto 35mm negatives – ARRILASER

Our lab is equipped with the only digital film recorded in the world that writes images onto 35mm negatives using a laser (elimination of flare in CRT recorders). Three extremely accurate (12 µm light beam) and stable light sources enable to record images originating from graphic files. Both the optical path and mechanical camera structure with the “dual pin registration” (Bell&Howell) option enable stable image location. Writing can involve colour (Kodak 5242, Fuji F-Cl 8502) or B&W materials (Eastman Panchromatic 5234). Additional options: CMS - Arri Color management enables adjustment of colour areas (calibrations) of a film projection to a video image (on a selected calibrated screen). Modul HD – enables writing in the natural HD 1920 pixel resolution, eliminating the need of scaling the original image. Alice – a suite enabling control of system configuration both in respect of geometry and colour calibration.
Sequence of DPX, CIN, TIF, TGA, SGI graphic files are used as the source for image writing. Such files can be supplied on any portable data storage device (a CD, DVD, portable USB flash drive or fire wire, streamer SAIT tape). We can also write images recorded on any video HD or SD storage device. We also offer digitalisation (copying) from any video storage device: HD, DigitalBetacam, Betacam SP, IMX, Betacam SX, DVCam, miniDV.
