Development of a video-multi- controller By Aske Haslund Fabech Edit by Nicolai Domingo Nielsen d. 20.08.14 Multicam productions with only one ope- rator is getting more common due to the related low production costs. Working with such a setup can be frustrating because most videoswitchers and PTZ controllers are designed for two-handed use. It ruins the workflow, resulting in dull static camera angles. Due to this frustration emerged the idea of a multi-controller that combines interfaces from a videoswitcher and a PTZ controller. It is the vision that one man can do a video production, that otherwise would require a whole video-crew. The project will prove that it is worth break- ing the conventional idea of professional production equipment, by expanding pro- duct boundaries with a more ergonomic interface. This project was a unique opportunity for the team's mechanical engineering stu- dents to utilize interdisciplinary skills through a product development process. The final result, with a working prototype had been unthinkable without the coopera- tion with SKAARHOJ. The Multi-controller has two joysticks, each of which can operate one PTZ camera at a time. The joysticks also control a video- switcher (ATEM). This combination of PTZ and videoswitch control is solved with 8 com- bined input/camera select buttons on the back of the joy-sticks. One joystick controls the program input and the ot- her controls preview. This means that a PTZ camera on the program can be in mo- tion while another PTZ cam- era on preview can be con- trolled as well. One operator is then able to make a transition between two inputs in motion, which is a highly unique feature. The Multi-controller prototype has imple- mented the most used PTZ and video- switch features such as camera presets, manual focus / iris, CUT, AUTO and more.

Computer-Aided Design (CAD) made it possible to go from a clay model to
(1) Working prototype(3) Developing process steps
(2) Input select positioning
an actual prototype construction made with additive manufacturing (3D printing). !The CAD-work succeeded in designing a model that can be customized to a user hand size for maximum work comfort. The CAD model needs further work for an optimal ergonomic design. All custom parts are manufactured with additive manufacturing which DTU has made available. !!All components are selected and positioned based on a analysis about hand size anthropometry. SKAARHOJ have been an incredibly effective and innovative partner in this process.!Alternative PCB designs (Printed Circuit Boards) were created in comparison to “New York matrix” designs. Also very thin PCB design where made, to experiment with mounting on curved surfaces. The technique was a successful implemented in the prototype, and might be used in future SKAARHOJ development projects. !
Parallel to the PCB design process, com-ponents where selected in cooperation with SKAARHOJ.!!
SKAARHOJ’s experience and flexibility made the component selection process simple and time-efficient for the DTU team. !
!When the prototype was physically ready, SKAARHOJ introduced their open-source libraries in a programming session, enab-ling the team to finish the programming themselves. Even with the teams limited programming experience the programming library made it possible to implement the desired features for having a working prototype. It has been challenging and exciting for the team to further enhance our skills within this area. !!The cooperation with SKAARHOJ has been fantastic and without their expertise in electronics and programming the proto-type wouldn't be a reality. SKAARHOJ has provided excellent support at all times, which is due to SKAARHOJ’s dedication and hunger for innovation.!!The DTU team thanks SKAARHOJ for an inspiring collaboration and look forward to equally successful collaboration in the fu-ture.!!DTU teammembers:!Kristina Pilgaard Jacobsen!Aske Haslund Fabech!Daniel Gert Nielsen!Mads Pilegaard Bjanesen!Nicolai Domingo Nielsen!Thomas Christian Riis!
