Questions with HD, 2K & 4K Film Digital Data Transfer
Digital Magic, Hong
Kong specializes in datacine transfer, digital intermediate
work, service for large volume of classic movies and television
restoration. Our film data transfer suite is centered around the
Cintel Millennium II Datacine/Scanner, with da Vinci color 2K
plus correction, and da Vinci ToolBox 2 for enhanced effects.
Cineon and .dpx Log Scanning is further supported by Cintel
DataMill for maximum control of DMax and DMin in the original
camera negative, resulted in extended range required for digital
intermediate work. The system can transfer film to SD, HD,
2K and 4K high-resolution data at high speeds with interactive
monitoring. HD is transferred in real-time, while
high-resolution 2K and 4K data are scanned at approximately 15
and 4 frames per second respectively.
At Digital Magi we
serve you with the world's only datacine equipped with a
pin-registered film gate, which provides the best stability for
film data transfer when VFX quality requirements must be met.
Aaton keycode system, and Digital Vision DVNR HD, and DVNR 2K
are added to provide image enhancement and grain control.
DVS Clipster is
online with all 2k and 4K data work, providing all
image data files needed for Vfx.
HD work are supported
with HDCam SR 4:4:4; HDCam, D-5, DVCProHD 100, and HDV.

Why MII for data
work, not the CCD approach
Our choice of
Millennium II is due to the fact that she is the best flying
spot CRT-based datacine that allow change of scanning sample
sizes to suit any filmmaker's creative needs. There is no other
CCD linear telecine or area array scanning devices like it.
Because CCD works under a fixed pixel sample size. With CCD
datacine, the film cannot scanned at higher sample
rates, especially when rescaling and zooming are required.
Flying spot techniques employed by MII allows manipulation
of the focal size, and also the shape of scan, result
with maximum resolution to suit any frame size or cropping need.
This approach is especially useful for anamorphic-based super
35mm film releases, where original vertical film resolution are
limited.
Millennium II
datacine is designed to scan in any resolution up to 4096 x
3112, compared with the CCD-based Spirit datacine which scans
only up to 1920 x 1440 resolution, well below the true 2K
resolution specifications. The method used by Spirit as to fill
your standard 2K frame requirements could only
be accomplish with an up-sampling of limited data, which we
believe has posed the risk of degraded image quality. In
general, we found the MII images are far more sharper, and film
grain could be recaptured for VFx creation, and film look.
Datamill help further to provide .dpx and .dpx.cin images
sequences for Digital Intermediate works.
The new phosphor
designed Millennium uses a "white light" broadband phosphor with
a significantly higher energy level. It offers an "afterglow"
fast decay rate, resulting in much less noise and a relatively
cleaner and improved film image.
The MII's rectangular
CRT design follows the shape of your selected scanning patch
without any loss of corner resolution. The new CRT faceplate
curvature design is specially applied to match that of the skid
plate to enhance constant focus.
Superior Performance
and Specifications Summary
1) a. The Millennium
II is a better datacine unit, as the Spirit samples luminance
information with a fixed 1920 sample CCD array, color
information produced with three 960 sampled RGB, CCD
arrays, resulting in 4:2:2 scanning. With Spirit, less color
information is made available than with luminance information.
b. Millennium II
datacine samples all 3 channels of RGB information from film at
full color bandwidth; a true 4:4:4 scanning. Millennium II
also samples 3 RGB 16-bit channels with 1920 samples each in
HDTV mode, and 2048 samples each in 2048 x 1556 at 2K data mode,
4096x3112 at 4K data mode. Even in 1920 x 1080 HDTV scanning
mode only, the Millennium II captures a perfect 4:4:4 image
that provides more information and color depth for your film
mastering work.
2) Many colorists
have problems reproducing certain colors with Spirit, and the
use of secondary color corrections is often required, because
Spirit's CCD sensor performs only 960 samples. With
Spirit, rescale image will cause throw away of image
information when zooming, panning or tilting. When zoom or
scaling is applied, the Spirit must carry out interpolation
processing which is equivalent to a DVE zoom, causing picture
quality reduction and degradation.
3) a. In 2K mode
film work, Spirit again must interpolate 1920 samples to fit the
required 2048 sample output. Color information, too, scanned by
Spirit only contains 960 samples. So the resulting image is only
4:2:2, or just with half of the original color information.
Picture steadiness is also a big question, which wide angle Vfx
post works has always been troubled with the Plus or Minus 2
pixels specification.
b. Millennium II
samples always fit fully and scan your desired total picture
area with maximum available pixel depth. When zooming, the
Millennium II CRT raster beam changes to fit the area of
the selected image. Millennium II also never loses any data, nor
needs to do any interpolation. In your preferred HD, 2K or 4K
mode, Millennium II always outputs the true, full bandwidth
4:4:4 color information. In our special MII config, you could
apply pin-registered film movement during the scanning process
for the utmost stable needed for Vfx post work.
4) a. Millennium II
datacine captures more information from film than any of the
Spirit units.
b. Spirit's CCD
array design also tends to have a "video look" while Millennium
II always has the much more preferred full resolution "Film
Look".
