KEMscreen technology

Recording without Extra Device

KEMscreen and STEevolution does not need any computer. It can be recorded optionally in camera (digital cinema workflow) or onto a hard disc recorder, a server system or directly on PC or Mac (video playout workflow) – in currently most effective and widespread professional video formats.

Better Picture Quality

KEMscreen and STEevolution affect in comparison to usual film editing tables with picture hoods a significant improved picture quality not only in terms of resolution and dynamic range.

The new, patented imaging system KEMcore (P)  developed by KEM provides a dynamic range that corresponds to the original picture-module. The brighter parts of the picture are typically lost during an ordinary video recording. Here the highlights are reduced by an optical low pass-filter and scaled into the dynamic rage of the digital cinema camera. This way all the information in the highlights of the film material are saved.

Calibration and Color Management

Thanks to the ICC-profiling of the new professional flat screen the editing table becomes a reference tool for picture comparison in between profiled systems in digital postproduction. KEM offers a scale of powerful video displays starting from a very affordable video monitor up to broadcast equipment. Of cause, already existing video monitors can be used as well.

Well Preserving of Content and the Historic Viewing-Technique

The table does not lose any of its reliability or visual character. Its features will remain the same, normally not even a drilling is necessary to mount the table interface instead of the picture module. The operation of the table remains as before.

The polygon of the table is retained, and with it the familiar and characteristic look of the editing table stays. For sound recording the analogue tape heads of the table are used so the character of the sound will stay as well.

A circuit had to be developed to create the synchronicity of the analogue film and digital image. Every single image can be checked in improved quality as a single picture, in shuttle mode and in real time.

Ergonomic and Representative: vintage Editing Table with Modern Monitor

The self-luminous display compensates changes of light in the environment in color and intensity and makes the installation location independent from the ambient light. Focus and brilliance counteracts visual fatigue.

The digital display has a significantly larger viewing angle than the ground glass of the editing table, thus enabling demos in front of more than one interested people. The camera can be controlled by a remote-app.

Formats

The system natively provides 4k ready, though a digital 16:9 HD Black Magic Cinema Camera is integrated by standard. Other Cameras can be installed or retrofitted on demand.

KEMscreen and STEevolution are optimized for 16:9 full-picture formats of S16 up to Super35mm. If respectively the framing can be fixed for visual co-recording of the sound track, 4:3 formats have to be re-formatted by cropping.

Future-proof Archive Formats

Video-playout workflow:

  • Digital Component Video (YCbCr) 1080p(4:2:2) as HDMI (or SDI via converter, uncompressed)

Digital-cinema workflow:

  • CinemaDNG non-proprietary, open Adobe RAW format incl. proxy preview
  • ProRes (4:2:2) in different bit rates (Apple/ ARRI)

This allows all options of a professional film postproduction and sustainable archiving.

Layout of KEMscreen

Heart of our digital retrofit-kit for analogue film editing tables is the new patented imaging system KEMcore©

This, plus camera and display, can be interchanged by the operator between the tables with a KEMscreen, resp. STEevolution table-interface that has been mounted by KEM-professional-staff before.
