Two years ago AJA released the Io HD, which provides almost every input and output that you could possibly want with direct-to-ProRes capture. The Io Express offers a similar (but smaller) feature set for portable capture to a laptop or (optionally) to a desktop on both OS X and Windows. Unlike the Io HD, the Io Express does not convert to ProRes in hardware. It sends uncompressed video to the laptop via a ExpressCard interface, like the Matrox MXO 2.

Io Express Features:

Having been working in the video business since 1988 I have amassed a great amount of knowledge of both the kit and production values over the last 30 years.
