Recording 10-bit Apple ProRes 422 direct to your Mac via a single FireWire 800 connection, AJA's award-winning Io HD is a portable plug-in solution for working with HD and SD.
Features of Io HD
Enhance your production workflow
Facilitating high-quality capture and playback with the widest range of gear, Io HD let's you record Apple ProRes files to any FireWire-equipped Mac.

Easily interfaced with your on set capture or post production equipment, AJA Io HD features professional video and audio connections, allowing it to enhance any workflow.

ProRes encoding and decoding
Integrating with the software running on your computer and utilizing efficient hardware-based encoding and decoding, Io HD handles the heavy lifting of compressing and decompressing ProRes files, keeping the load off your CPU and providing superior quality encoding/decoding compared to software-only solutions.

With AJA Io HD, video professionals can avoid lossy tape compression and capture footage to high quality 10-bit, full raster Apple ProRes 422 files - ready for use immediately in your editing software. ProRes can create images that are virtually indistinguishable from the source, while the 10-bit sample depth means the results are easily suitable for color correction and compositing.

Because the files are compressed or expanded directly within the Io HD, the actual data that has to travel to or from the computer is much smaller than if uncompressed HD video were being transferred. This allows Io HD to utilize a standard FireWire 800 connection.

Huge I/O flexibility
Io HD's comprehensive connectivity allows it to interface with the widest range of post production and on set capture/playback equipment, from HD VTRs and cameras through to analog legacy devices. The rear panel features two SD/HD inputs and two outputs, one connection for Genlock input and a loop-through, and two groups of three BNCs which may be configured for component SD/HD analog video input and output. HDMI input and output allows interfacing with low-cost camcorders and HD monitors. Add to the list S-video, composite video, LTC in and out—and a 9-pin connector for RS-422 machine control and you can connect to just about anything.

Audio support includes 8-channel 24-bit AES via BNC, 8-channel embedded audio on SDI/HDMI I/O, and analog connections via XLR and RCA.

Integrated AJA hardware conversion
Using AJA's powerful conversion technology, Io HD allows you to ingest any resolution and convert to a common, working format. This brings greater efficiencies to your post production workflow as individual shots no longer have to be rescaled within the editing or graphics application.

AJA Io HD features full 10-bit, broadcast-quality, motion adaptive SD to HD up conversion, HD to HD cross conversion, HD to SD down conversion, and HD/SD 12-bit component analog output. That's the equivalent of fitting the functionality of several AJA converters into one convenient, cost-effective box Io HD conversion capabilities streamline the creation of dailies and deliverables at broadcast quality - in real time.

Up-Conversion • Hardware 10-bit
• Anamorphic: full-screen
• Pillar box 4:3: results in a 4:3 image in center of screen with black sidebars
• Zoom 14:9: results in a 4:3 image zoomed slightly to fill a 14:9 image with black side bars
• Zoom Letterbox: results in image zoomed to fill full screen
• Zoom Wide: results in a combination of zoom and horizontal stretch to fill a 16:9 screen; this setting can introduce a small aspect ratio change
Down-Conversion • Hardware 10-bit
• Anamorphic: full-screen
• Letterbox: image is reduced with black top and bottom added to image area with the aspect ratio preserved
• Crop: image is cropped to fit new screen size
