Example for a soft edge projectionIn Wings Vioso RX a show can be presented on a number of video projectors or displays, thus implementing unusual and extraordinary presentations. It is therefore possible to produce extreme panorama formats in seamless soft edge technology at a quality that exceeds HDTV standard. Or, an arbitrary number of displays is arranged into highly interesting audiovisual sculptures, the contents of which are perfectly in harmony with each other.

A multidisplay show is split up into three stages:
Planning the screen format and creating the project
Arranging media, effects and timeline functions
Presenting the show

order to find out about the Wings Vioso RX
we have prepared sample projects on the Wings Vioso RX
DVD with all the necessary media as well as short explanations and the
links to the corresponding help topics.
First of all you should think about the format of your presentation and the way the individual screen fields are to be arranged. In Wings Vioso RX the overall image is displayed on the screen and can be produced by a number of video projectors or displays. The area to be covered by a video projector or display is defined by multidisplay areas. For a soft edge projection you can allow about 20 % for the overlap of the multidisplay areas. Depending on the format you can have several video projectors arranged horizontally (panorama) or vertically (portrait format). Of course, it is also possible to assign the video projectors to both axes, so as to increase the resolution, for example. The Wizard for mixed media projects assists you in creating the projects and calculates the missing parameters, e.g. softedge overlap after you have specified a number of parameters. Of course, it is also possible to position every multidisplay area separately and individually on the screen. After that the presentation network is configured provided you are using several networked client-PCs. For soft edge projections you also need to adjust a ramp for the gray scale masks. This softedge mask is only added by Wings Vioso RX during graphics card output. This means that the media themselves do not need to be provided with a softedge mask thus considerably simplifying production. If you have got Wings VIOSO, it will allow automatic camera-based image calibration with regard to geometry and softedge masks.
The difference between production of a multidisplay show and a normal show is very slight. They actually only differ in the output. You arrange the show on the master which transfers the media and project data to the clients in the presentation network. One computer can supply content to up to four displays. The number of clients can be arbitrary. Audio playback is exclusively via the master which can output up to 32 channels via appropriate audio hardware. The master is also able to provide the image signal for up to four displays or video projectors. However, during production one graphics card output should be used for the control monitor as it allows more comfortable editing.
During production you can use hardware rendering for representation in real time as you would for a normal show provided automatic transfer of the media data to the corresponding client computer is complete. All computers on a presentation network immediately display any alterations upon a mouse-click so that the details of your show can very accurately be edited. If for some reason the presentation hardware should not be available, e.g. when the clients and video projectors are currently used for a different event, you can still continue to edit the show on the master and evaluate it on a smaller screen on the local monitor. If necessary, any sequences produced such can later be optimized via the presentation hardware.
Presentation can either be via hardware rendering or in the form of a rendered video. The latter will be required, if a show contains a great number of simultaneously running videos which would no longer be played back without any problems via hardware rendering. Of course, it is also possible to control peripheral devices via an SC Net (Show Control network) as well. For live presentations, spontaneous dissolves via track sliders or triggers are also possible during playback - these can be pictures, video or sound. Even the integration of live video/TV signals across several multidisplay areas is no problem. However, every presentation computer involved needs to be supplied with the signal via a suitable video input card.
