We’re pleased to announce the release of MediaMaster 1.1 with major improvements pushing the boundaries of professional video projection another step further Designed specifically with the show and lighting market in mind, MediaMaster1.1 now comes with improved frame blending support allowing extremely smooth video playback even at slow speeds and software genlock making it possible to play several HD movies at up to 60 fps without dropping a single frame. Other new developments include higher possible output resolution (up to 4096 px), Alpha Channel from source, support for grandMA’s MA-eDMX protocol, improved SoftEdge blending and more.. If you want all the details, we’ve got a nice Press Release for you. And if you just want to use it, it’s here and it’s a free upgrade for MediaMaster 1.0 users.

MediaMaster 1.1 brings important modifications to our video engine and particularly how the video synchronization and multi threading decoding is processed. It has been optimized to perform what can be called “software genlock” in order to ensure the best possible fluidity on computers equipped with multi core processors. The genlocking we refer to is the action of locking the frequency of a media to a reference signal or clock (check out the related wikipedia article for a complete explanation). Let’s examine quickly the process of displaying frames. Roughly, 3 steps must be acheived:

We’ve been working hard since 3 months on the next upgrade of MediaMaster: the version 1.1 which will be released in a few days. All the new features will be announced with the release but here’s already a video tutorial demonstrating the new support in MediaMaster 1.1 for grandMA’s MA-eDMX protocol.  This allows a much better networking between grandMA lighting consoles and a media server running MediaMaster.

There’s a certain point where it becomes very hard to demonstrate to a large audience what you do. As we strive towards the limits of the extreme, it becomes more and more difficult to demonstrate in a simple way the results of our work. Last couple of month, we’ve been working very intensively on the new release of MediaMaster (version 1.1 – which should be out very soon). One of our goals for this release was to improve radically our engine to be able to run a couple of movies at monitor rate with no frame drops. 60 fps that is. And we did it. This means that you will be able – of course depending on the computer and the movies you are displaying – to run movies perfectly locked to the monitor sync. The result is brilliant – even for movies at 30 fps – because your eye directly catches the smoothness of the playback.

LoopLight sent us this video from what they did at Nature One festival on the “House of House” floor. They have setup a very creative system to trigger visuals involving a NuVJ, a video camera, a MediaMaster controlled from a GrandMA console and.. a custom controller made of a simple plexiglass panel with duct tape, the so-called “PixelFucker controller”.. Philipp from LoopLight explains his creation:[video theremin]Installation schema

Here’s a quick tutorial on how to use the LED Mapper extension to map the output from ArKaos MediaMaster to a wall of 6 Schnick-Schnack C100 LED Panels. As you will see, it’s pretty self-explanatory and really easy to achieve.. There is no specific hardware necessary to convert the video signal for the LED Panels, ArKaos MediaMaster outputs the signal in ArtNet through an Ethernet cable that goes to a network switch connecting the 6 C100 panels together. The total surface is 6 sq. meters (3x2m) and 18 DMX universes are used to drive the 2400 LEDs.

Back in March we featured a show report on the ArKaos web site about the installation made by lighting designer Sebastien Jurkowski at the Zouk Club in Kuala Lumpur. This impressive setup in a not less impressive venue was the very first time our brand new media server software ArKaos MediaMaster was used in a Club installation and it proved to be a very good and reliable solution since it is now the subject of a 3 pages article and interview in mondo*dr magazine, the international publication for technology in entertainment. Here is a short video clip from the installation in the main room at Zouk Club, read further below for some interesting parts of the article.

When it comes to media playback, at ArKaos we always fight to get the best out of current computer configuration. When you are in the show industry and try to find out the best way to compress your content it’s still a little bit of black magic. While some codec are able to compress video very well they are heavy to handle for the machines, even more, the codec that does the best job at compressing while keeping a good quality such as H264 are very bad when you need to scratch your media. The best codec for users that need to interact a lot with the content should allow to play forward and backward easily and should allow to jump into the content quickly.

Here’s a quick tip for PC users: if you use a multi-core/multi-processor machine with GrandVJ orMediaMaster, you will benefit a lot to use codecs that are played through our FFMPEG player rather than through QuickTime. This is due to the fact that on a PC, the internal QuickTime decoding routines are not capable of multi-threading, which makes it impossible to decode frames in parallel. So even if one layer can run properly using QuickTime libraries, the more layer you pile up, the more the decoding bottleneck will show up. On Mac OSX, QuickTime is now mostly multi-threaded decoding so it’s not such an issue but we recommend to try to use codec supported by our FFMPEG player in any case.

When your frame rate goes down, and the video starts lagging, it is important to be able to analyse where it can come from. Today we’re going to look at some information we can use to troubleshoot this. Roughly, the way our application works is the following: at each pass, we read  a video frame from the disk if needed, decode it and then send it to the GPU (the Graphic card’s CPU) together with all blending and effect operations. Then we ask the graphic card to flush all operations (that is actually processing all pending graphical instructions) and present it to the display. If you look at the bottom of the user interface window in either NuVJ, GrandVJ or MediaMaster, you will notice that there are two numbers constantly updated. Something like:Graph: 400.00 Total: 60.00 These numbers indicate the speed at which the engine does its rendering.
