Using cues, timelines and VJ software for performances

These days as a part of the Obscura crew I am ofting doing visual shows that have more in common with theatre productions than traditional VJing. Often there is some sort of script for a show or a piece of music that is rehearsed. For these types of jobs I have found good use for the application called QLab which is great for triggering a pre planned sequence of events. Actually the whole point of QLab is to line up a sequence of audio, video files or other types of events and being able to trigger them with a simple ‘Go’ button at the exact right time during the show. QLab was originally developed with audio in mind and has later been extended with video features so it does not have many features as VJ applications when it comes to live manipulations of images and video. But for those of […]

Concrete forest

Concrete Forest – an art project that turned into a party from Obscura on Vimeo. The video shows the result of a fun little project we did in collaboration with artist Louise Bech Pedersen. We cut out these animal figures of a special acrylic rear projection material and used them for mapping using Modul8 and MadMapper. Doing the mapping was trivial using these tools – it was the acrylic material itself that proved to be a bit of a challenge. The light projection properties of the material were terrific, a clear and bright image from all angles. For people like us who are used to projecting onto fabric or walls it was a joy to see the brightness of this professional screen material. However the material was a quite brittle and cracks appeared a few places even when using a saw made for use with acrylics. And the deer lost […]

Developing visuals synced to a music composition

Recently I have had the pleasure of working with Linda Edsjö a classically trained percussionist and composer Simon Christensen in developing visuals for a piece of modern compositional music. The project was unusual for me as we decided to try to connect the visuals computer with the computer that was running the musical backing track. That way it was possible to obtain a perfect sync  between music and image. The music was composed as a piece in the Max/MSP software and this was linked to Modul8 (the visuals) through midi. The music software was sending midi on every beat and another midi signal whenever the music entered a new section of the piece. To achieve the result I wanted I had to program two small modules for Modul8. These modules were in charge of turning layers on and off, applying effects and switching between images.

Modul8 quick tip: Keep track of your files with links

All users of Modul8 encounter the problem of keeping track of files in their projects I suppose. Sometimes you want to reuse media in new projects without creating extra copies of them and thereby cluttering your hard drive. Still you want the media collected in the same folder as the project in order to not break anything if you rename or move the original. You might think that creating an alias of the media would work, but Modul8 doesn’t import aliases. I found another solution in the Terminal command for creating ‘hard links’. A hard link works a bit like an alias except it appears to be an actual file and it works in Modul8. In reality there is only one copy of the movie taking up space. And even if you rename, move or delete the original file the new file will continue to work. EDIT: One caveat I […]

Projection mapping on the rise

As visualists have noticed already and known for some time now, projection mapping is cool. And now it seems that this technique is going mainstrem in a big way as it is beginning to be used more and more in commercial contexts. In my city I am noticing more and more outdoor video projections – some of them using mapping techniques. For those who stumble upon this article and are not familiar with the term, projection mapping is the technique of beaming video (with a standard video projector) onto three dimensional objects and adjusting and masking the image so that it seems to follow the shape of the target object instead of spilling out onto walls etc. The result can be surprisingly effective and eye catching as the video is no longer a flat square on the wall but becomes an object in space – an animated sculpture if you […]

Working with Quartz compositions in Modul8

In Modul8 you’re able to play Quartz compositions (.qtz files) just by dragging them into your media bank like any other movie. However there are a number of problems with this approach: No 1. Performance. I have done tests and often there is a severe drop in framerate for qtz files in Modul8 compared to the framerate in the Quartz Composer editor. No 2. You cannot decide the rendering size of .qtz files in Modul8 (in version 2.5). They are always rendered as 640×480. In Modul8 v2.6 you can set the size in Preferences but there may be many situations where you’d like to set the size for the individual files. No 3. You cannot set the duration of .qtz files in Modul8. Duration will always be 30 sec. I find that these problems can be solved by following the steps below and converting the .qtz file to a .mov […]

Quartz Composer performance in Modul8

I’ve been doing some testing and it’s my impression that you get a much better performance in Modul8 if you convert your .qtz files to .mov before importing them to Modul8. This can be done by following the steps described in this article: Working with Quartz Compositions in Modul8 I don’t know the reason for this so I don’t know if it’s a general problem or something that is limited to my OS/hardware combination. I’m running Snow Leopard on a 2.4 GHz duo core Macbook Pro. So if you’re curious here are the files that I’ve tested with. I get approx. 14 fps with the .qtz but 57 fps with the .mov in Modul8. In Quartz Composer editor I also get around 57 fps. particleleaves 6 (mov) particleleaves 6 (qtz)

First impressions of Arkaos GrandVJ 1.2 beta

Arkaos is out with a new beta for version 1.2 of their GrandVJ application and that prompted me to check out their software. Especially since they promise support for native Quartz Composer files. The new beta is out for both Mac and Windows. grab it here: So now I have the beta and since I am a seasoned Modul8 user I thought I’d try and do a Modul8 versus GrandVJ feature comparison. Keep in mind that I have a total of 5 hours of experience with GrandVJ versus 3 or 4 years with M8, but I will try to be fair and balanced. General impressions of GrandVJ The basic idea of GrandVJ is not that foreign when coming from Modul8. A lot of the features are pretty much the same in both apps and I don’t cover those here. For instance the midi mapping and key mapping seems to work […]

New module for Modul8

For a couple of years now I have been using the VJ software called Modul8. One of the nice things about Modul8 is, that people with a bit of programming skills are able to augment the application by adding so called modules. I have just made my first module – it is available for download and is called ‘Crop layer (Udart)’. It’s a simple module to make it possible to crop the picture in each layer. Look out for more modules to come (I hope)

Controlling Modul8 with your Iphone or Ipod Touch

I have found out how to use my iPod Touch as a controller for the Modul8 VJ app. You need the OSCemote app for the iPod and the OSCulator app on your mac. Here’s the recipe: 1. On the iPod Touch / iPhone go to app store and download OSCemote. You can try the free version first just to try it out 2. On the mac download OSCulator from here: 3. Install Osculator and look in the folders for the OSCemote file. Launch the Osculator by opening this file 4. Open OSCemote on the iphone and fill out the IP address and port of your Mac. Make sure the port is the same as configured in OSCulator. You should see a ‘connected’ message. 5. Try some of the buttons and see how the lamps in OSCulator light up yellow to indicate there is a signal Now you can try some […]
