Quartz Composer built stereoscopic recorder

Here's a nifty OS X application that creates red/blue 3D movies using input from two firewire cameras (like the two iSight camera setup featured in Res magazine a while back.

Content-Aware Image Resizing

Yet another Siggraph video that blows my mind -- "Seam Carving for Content-Aware Image Resizing" by Shai Avidan and Ariel Shamir.

(via AE Portal News)

Part of what's so interesting is the idea of finding patterns in images/video that allow a system to be "content-aware". The use of edge detection to determine important vs. non important visual information reminds me of the process of analyzing time-sliced video footage to interpolate when cuts, dissolves, or wipes take place. Eddie Elliott has a great example of this on his website. Essentially, if you take all the frames of a video and place them back to back to make a cube, by looking at the sides of the cube you can see where a left to right wipe, a cut to different looking footage, or a cross dissolve take place. Someone told me a couple years ago about a company trying to refine the technique in order to create a software program that logged archived footage procedurally, rather than hiring someone to plod through hours of footage.

Steve Jobs poo-poo's little plastic discs for video

During the iMac/iLife special event Steve Jobs introduced the iDVD part of the package with a dismissive "There are some people who still want to make DVDs." This followed a demonstration of some really nice HD web galleries being generated by iMovie. It's nice to know somebody that high up has caught on to the fact that locked-up oxidizing plastic discs that are illegal to copy are a bad way to hold video.

Panic's Steven Frank chimes in.

(p.s. I know I'll probably sound like an Apple shill for saying this, but I just got one of those new iMacs, and it's the nicest computer I have ever worked on, and that includes the quad Mac Pro I use at work. The glass front LCD and keyboard and overall zippiness of the machine just plain make me happy whenever I use it. I just put FCS 2, Logic Pro, and all my assorted free video transcoders on there and it positively sings.)
