Read about this just now:

Raspberry Pi | An ARM GNU/Linux box for $25. Take a byte! (http://www.raspberrypi.org)

Long story short, it's a credit-card sized, $25, Linux-based, fully programmable PC with USB ports and some kind of video connection, among other things.

Wondering if there's any way someone (I know squat about programming) could use this as a video i/o box like Matrox, AJA etc., to get NTSC compliant video signal out of NLE or After Effects etc. to a HD monitor.

My prediction: No. For some reason.

Interesting little "toy", the video is either via composite or HDMI, I'm not sure what you'd use as an input... perhaps some USB dongle... Since it's Linux, I'd expect a lot of possible options might be available for file playback.

I never really got into the nuts and bolts of programming, but as far as a cheap computer goes, this obviously has potential... poked around the site, and see there's a possible Android port.

Your best bet for video output is a live H.264 stream into the Raspberry Pi (but it will be delayed)

The bandwidth requirements for uncompressed video may be too great for the machine. Compressed video can be decoded accelerated with the onboard GPU.

You're probably going to tell me I don't want to grade/color correct compressed video, right?

Shoot, most of the time I could get by looking at still frames for grading purposes, as long as they're color accurate.

You could do low frame rate Uncompressed if you can feed the data into the Pi via something like Ethernet. You still gotta write drivers to output your Windows or Mac based AE/Premiere output to stream to the Pi.

My...um ...hope was that someone ELSE would do all that and i woulld buy it from them. Or buy the code. Or however it works.

In the open source community, there is no such thing as buying code. It's adapting/improving on publicly available code.

Ah. Well...then hopefully some programming-savvy person with a passion for color correction comes along and makes it happen. Unfortunately that guy aint me.
