3 PRODUCTION-SIDE ACCEPTANCE FACTORS
The 3D VIVANT concept can have far reaching implications for the production of content. The new
camera sets will have to interface with existing technology and may require further technical
developments. But also production processes and workflows will be impacted by the technical
developments and the opportunities they offer.
• The editorial department may have to (re)write scripts to take full advantage of the holoscopic
imagery.
• The camera department will have to find out how to work creatively with the holoscopic image;
especially the technical aspects of the camera’s setup will be important for them. They have to
work with the holoscopic camera and, therefore, they will have precise ideas of how a basic setup
of the camera has to work. There should be the possibility to monitor the 3D holoscopic images in
terms of creative decisions and in terms of technical ones. For the creative part, the requirement is
to see a 3D image like it would be recorded, to set the depth and to position all objects/actors in
front of the camera and to judge lighting, etc. In terms of technical decisions, the camera
department would need some measurement techniques to judge the image with respect to overall
picture quality usually controlled via waveform monitors, vectorscopes, etc. It has to be
investigated if these 2D measurement instruments are still sufficient to judge holoscopic images.
As the 3D holoscopic image will be captured in a different form the conventional ways, it is
possible that these techniques are no longer adequate and the measurement techniques have to be
modified or new ones developed.
• The director needs 3D playback to also judge the final composed image and the acting while
recording.
• During postproduction, both creative and technical monitoring (holoscopic display and
waveform/vectorscope) is needed.
Production side validation activities will concentrate on the holoscopic camera sets to be developed in
the project and also on the production processes for the service scenarios envisaged in the use cases.
3.1 HOLOSCOPIC CAMERA SETS
The project aims to ultimately produce a single tier holoscopic camera. Initially, a two tier camera
will be produced. However, to make 3D content generation accessible to partners, it is also planned to
develop an add-on optical hardware, which can be used with an HDTV camera equipped with the new
imaging sensor. As the camera solutions developed will be prototypes, as opposed to finished
marketable products, the proposed approach is to conduct a technical comparison of camera sets
produced by the project with other 3D solutions (commercially) available. It will be necessary to
consider items related to the calibration of system, as well as to list what existing technology in the
production process is impacted by the camera itself and the output, i.e., the 3D holoscopic images it
produces.
Annex 1 contains some tables in which the main parameters involved in a TV production are listed,
with the indication of the monitoring tool and/or measuring instrument usually adopted in a TV studio
or a post-processing environment. Some of the parameters and monitoring or measuring tools should
be equally relevant for 3D holoscopic productions; others may have to be modified to suit the needs
of 3D holoscopic shooting.
Like in 2D shooting, basic parameters such as focus, aperture and focal length have to be adjustable
and controlled via adequate monitoring tools. For stereoscopic shooting, additional depth related
parameters, such as screen position in depth, transversal and longitudinal magnification and
