Scott [amoeba], a long time ArKaos user (since 1998!!) has just published hot news on his web site theestateovcreation. If you don’t know [amoeba] yet, it’s really time to check it out and discover his very unique style.

[amoeba]‘s creation/mixing process involves a lot of different tools such as After Effects or Ableton Live and various techniques like typography and animation generally mixed an synced together whit GrandVJ.

Blindskunk, an ArKaos GrandVJ user from Australia we found on Twitter has made an interesting experience about creating an audio/visual clip usingGrandVJ and Yamaha’s Tenori-ON.

The interest of this experience is that Blindskunk uses the musical instrument capabilities from the Tenori-ON to produce the music and at the same time its MIDI controller capabilities to trigger GrandVJ visuals in sync. To do so, he has linked every channel and button from the Tenori-ON to a visual in GrandVJ, and got that visual to play in time to the changes.

Ok the title is probably a little bit simplistic but there was no way I could fit the whole setup Momo and other VJ’s had installed at Coachella in just one sentence.. So I just picked up the 3 NuVJ‘s :)

If you read this article from Momo The Monster himself at Create Digital Motion you will understand that VJing when done professionally is a very serious job which requires good software, quality hardware, nice visual content and an incredible lot of planning and organization – in case you didn’t figured this out already..

How to create interactive Flash animations for GrandVJ? Learn with the pros and raffle a free license!

ArKaos is pleased to sponsor La-Va.org’s Flash Video Mixing Workshop: an afternoon of lectures, live demonstrations, and discussions of programming techniques, platform quirks, and methods of creating interactive Flash visuals in a live setting.

Flash animation has become a weapon of choice in a VJ’s arsenal due to its small file size, flexible scalability, and (most importantly) the potential for interactive programmatic elements.

Students from the HackCollege – a blog about life hacks for college students – have just posted an article about the last party they organized in LA and how they have used GrandVJas part of the gimmick at the party.

Kelly Sutton, the article author, blogs about their experience with the DV2 laptops that HP has kindly provided them for the weekend and how it has been put to contribution for the party as a very simple VJ station that every guest could play with; here are some quotes we liked a lot :)

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.

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.

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.
