HD4NDs’ Mike on Building Your Own HD Workstation -

Mike of HD for Indies fame has an article on DV.com on building a workstation (Mac or PC) for HD editing and post/correction.

Getting the right gear involves lots of decisions. I often spend an hour or two reviewing filmmakers’ or producers’ needs before we arrive at a system recommendation. Every shop and every project has its own peculiarities, so don’t take this list as gospel. It might be worth (ahem) consulting with someone whose advice you trust to fine-tune your needs, budgets, expectations, technical comfort level, and other factors. Myriad little extras and doodads make the system complete, but those are beyond the scope of this article. Suffice it to say you’ll spend a bit more than the following tallies by the time you’re done.

Apple WWDC Tracks Hint at New Visual Capabilities in OS X Leopard

We already knew that Leopard would be a major new OS release for Apple in the visual sense with Core Animation, much as Tiger was with Quartz Composer, Core Video, and Core Image. We should know a lot more at Apple’s developer conference in June. There are some additional details in Apple’s latest WWDC announcement, under “Leopard Innovations”:

  1. Core Animation to add elegant animations to your application interface.
  2. iChat Theater to incorporate application content in iChat.
  3. QuickLook to provide system wide previews.

Core Animation is old news, but could this mean you could add iChat streaming to an app? And system-wide previews are also badly-needed.

Generative Inspirations: Texture Glitch, Flight404 Processing + Lemur Goodness

If you ever want to stimulate the visual centers of your brain as you work with your graphics tools of choice, there’s endless inspiration from the visualist blogosphere.

In case you missed it in comments, our friend vade has done some terrific work using Max/MSP/Jitter and “glitchy” texture mapping. I just now noticed he was using audio input to do it, which can be a terrific way of modulating visuals for organic results. (Without knowing he had done that, I tried some similar experiments this weekend using the audio peak input in Quartz Composer.) The effect is simple but incredibly effective: play with texture coordinates so that the textures come alive. Don’t miss the first video.

This would be equally applicable to Processing, Quartz Composer, or anything else that does even basic texture mapping and audio input.

Meanwhile, in Processing Land, generative virtuoso Flight 404 (Robert Hodgin) has done amazing things with a particle system, magnets, and circles:

See also this (earlier?) magnetosphere video (thanks, Jaymis, who was impressed enough he said something PG-13 about its awesomeness.)

Utterly stunning, and better yet, he’s included Processing code and walked through the whole process of building it. Check comments for more insight. But Robert didn’t stop there. He’s gone and bought himself a multi-touch Lemur controller, with still more cool videos:

Pretty lights! [Flight 404 blog]

I’ve been critical of some aspects of the Lemur in the past (see my Keyboard Magazine review), but it has been improving, in terms of the flexibility of the interface and how it assigns MIDI and OSC messages. One key advantage for visuals that can be less of an issue with music is stutter-free control of on-screen elements (which requires a higher resolution), and generally having an interface that lends itself to controlling 2D and 3D visual elements.

And, of course, in Robert’s hands it does some wonderful things.

Why am I putting these in the same post, other than sheer laziness? What strikes me about the effectiveness of each of these examples is that the quality of motion animates them in a way that is organic and alive. In each, the core technique and visual elements themselves are relatively simple, but the rhythm of the gesture of the visuals motion makes them more engaging. That, and just focusing on these two ideas, there are countless possibilities in whatever environment you prefer (Jitter, Processing, or something else).

Perfect Portable DVD Solution from Kawasaki?

Computers are wonderful for making live visuals. But there’s something to be said for 2-channel video mixing on DVD, even if it’s just as a backup system for your computer rig. Via the Japanese site envol! VJ, we find this lovely gem from Kawasaki: dual 7″ displays, integrated dual DVDs with dedicated outputs, and dual audio. If this doesn’t scream portable 2-channel audiovisual mixing, nothing does:

Kawasaki Mobile Video System with 2 DVD Players and Monitors - PVS297OS [Amazon.com info in English FYI, though they have no stock]
envol! VJ audiovisual knowledge database

10 lbs. total, so it’d be easy to add to an existing laptop / SFF rig. Unknowns: reliability, how to buy one, if there are better options out there.

There’s an additional blurb on another Japanese site for those of you who read Japanese. I don’t, but I see GameCube, N64, PS2? Do they just mean that you can hook these up to the display (as with any analog input)?

Any other tips on these kinds of players? A lot of the cheap portable players I’ve seen were of, ahem, questionable quality.

First Impressions Review and Unboxing Pictures: Numark AVM02 Video/Audio Mixer

By Jaymis

I have just received and unwrapped my shiny new Numark AVM02 mixer. Unfortunately way too late for the 3 gigs I had over the weekend, so it will be a week or so until I have a hands-on, performance review. In the meantime though, I have plenty of first impressions.

Numark AVM02 Unboxing 04

It’s shiny. It’s big (19″ rack standard). Build quality is very solid - no surprises there - and all faders, knobs and buttons feel like they’re attached to a professional mixer. The crossfaders are a little slow, needing to be pushed all the way across rather than travelling there with a flick, and the lack of ”transform” buttons rules out some fun mixing tricks which can be performed with the V4, but perhaps this will encourage me to develop better crossfader technique.

It has many inputs and outputs. Ignoring the audio stuff for now (which is so passe darlings) we have 4 S-Video and 4 Composite in (not switchable, not sure how it selects between them). 2 S-Video and 2 Composite out, and 4 composite monitor outs.


Put it next to the V4 and one thing is instantly apparent: You’re getting a lot of mixer for your money.
