GridIron Flow Goes Beta

GridIron Software’s new product, Flow, has entered public beta today.

Flow is a revolutionary piece of software for designers—a visual workflow manager. It tracks files as you work on them, keeping tabs on the different versions and dependencies. It promises no more lost files, no more version hassles, and no more dependency nightmares when one project relies on changing media from another project.

25th Anniversary of the Macintosh

Macintosh_128k

Happy anniversary, Mac.

25 years ago, Apple introduced the Macintosh and changed the way we thought about computers.  For anyone outside a research lab, a computer with a graphical user interface was a revolutionary change in the way we worked with computers.

The Mac was a huge innovation, and its influence is still felt today, but our interactions with computers since its introduction have been largely evolutionary.  Seeing multi-touch and speech recognition technologies taking hold in our daily lives today suggests we are on the cusp of revolutionary change.

It’s very exciting to think that we are starting to design our computers to interact with us, instead of forcing us to adapt ourselves to our computers.  The implications in communications are huge. Most of our presentations today are static, with viewers passively receiving messaging due to technological limitations. Now, we are developing the tools to convert our viewers into participants, letting them interact with our messaging dynamically—even physically—with sight, sound, and touch.

Here’s to the next 25 years.

The Yellow Line

Just a couple weeks before the Superbowl, here’s a video that breaks down the technology behind the yellow first-down line on TV broadcasts for American football.

It’s a live compositing system that reads live camera position data from each camera on the field and draws the line over the video feed through some color filtering which masks out the players.  I was struck by the simplicity of the engineering, using a spare audio channel from each camera to carry camera position data.

OpenCL 1.0 Spec Ratified

The Khronos Group announced the ratification and public release of the OpenCL spec earlier this week.  OpenCL is a new industry-standard framework that will allow the powerful but specialized chips on graphics cards to be used for crunching numbers, just like the general purpose CPU in a computer.

That’s a lot of geek-speak to say that a lot of time-consuming multimedia tasks are about to get a lot faster.

Today’s graphics cards are capable of some serious mathematics, but they’ve always been restrained to using it to push pixels live to the screen.  Essentially, a graphics card contains thousands of cores, all of which work on a small piece of the screen image in parallel, or at the same time.  A general purpose CPU, on the other hand, typically has fewer cores (today’s most powerful desktops have 4 or 8), so they must process operations serially, or one after another.

With technology like OpenCL, a GPU’s raw processing power can be harnessed for some general computing tasks which can be broken down into independent steps which can run at the same time, like complex simulations or video compression.

The next version of Apple’s Mac OS X 10.6, expected for release in 2009, will feature this technology.  The upshot for media producers like myself is that sometime in the next year, we will spend less time rendering and compressing our work, freeing up more time to perfect the design itself.

LG Stretch — Double-Wide LCD Display

LG Commercial Stretch Display

In live events, we use non-standard, wide aspect ratios all the time.  3:1 (three times as wide as it is tall) is not uncommon.

Now, LG Electronics has released two extra-wide LCD displays.  The LG “Stretch” series introduces 29″ and 38″ models, with aspect ratios of 2.85:1 and 3.43:1, respectively.  They feature RGB and DVI inputs, and RS-232C control.  Resolution on the 29″ model is 1366 by 480, and the 38″ model is 1366 by 398.

Designed specifically for signage, I expect these displays will be popping up in retail and hospitality very quickly.

For events, they’d be perfect for digital agenda signage as well as delay screens for widescreen shows.
