Chapter 1: Introduction Overview AJA's Io HD is an easy to use, transportable, plug-in solution for working with HD and SD in Final Cut Studio 2 or newer. Connecting to a Mac Pro or MacBook Pro with a single FireWire 800 connection, Io HD uniquely supports the amazing new Apple ProRes 422 Codecs natively, in hardware, to bring production-quality HD editing to the desktop.
2 Io HD does all of this with unique simplicity, using a single FireWire connection between it and the Mac—while serving simultaneous realtime connection for all audio and video sources. How does Io HD transfer 10-bit full-raster HD video/ audio over FireWire? It efficiently uses the IEEE 1394b 800Mbps FireWire port on the Mac for all data transfer—and since Apple ProRes 422 is optimized for 145 Mbps (normal quality) and 220 Mbps (high quality, HQ) there is plenty of bandwidth.
Io HD Installation and Operation Manual — Features • Front Panel Audio VU LEDs: 8-channels (green/orange/red showing normal, over-limit, and clipping). • Front Panel Alphanumeric display: shows input and output settings and other system information and alerts. • 3-year International Warranty, with unlimited Technical Support. Broadcast-Quality Conversion Io HD features hardware based full 10 bit broadcast quality motion adaptive SD to HD upconversion, HD to SD downconversion and HD to HD crossconversion.
4 The Io HD driver also provides RGB support, allowing for direct video output of applications such as Adobe After Effects,™ and Apple Motion™ to name a few. To make Io HD even more useful, we’ve included a number of AJA utility applications: AJA TV, AJA System Test, AJA Data Rate Calculator, AJA QTtoDPXtranslator, and AJA DPXtoQTtranslator. Note: These utilities are also available for free download at www.aja.com/html/ support_iohd_swd.html as well as being part of the Io HD installer.
Io HD Installation and Operation Manual — System Requirements Please save the Io HD shipping box and all packaging materials. If you ever require service or want to move your system—use the packaging materials and box for safe shipment. System Requirements AJA Video recommends that your system meet minimum hardware and software requirements to achieve a satisfactory level of performance.
6 Understanding Disk Storage Methods The Io HD with an Apple Mac Pro or Apple MacBook Pro and Final Cut Pro 6, along with a suitable storage system, offer an unprecedented level of features and performance for all audio/video production applications. However, to ensure performance and quality, the disk storage system used with the Mac Pro or MacBook Pro must be able to meet the demands of storing realtime uncompressed SD media and ProRes 422 HD media.
Io HD Installation and Operation Manual — System Requirements Striping divides a logical drive into data blocks, or stripes, that are distributed across an array of physical drives. Striping a set of disks improves storage performance because each drive operates concurrently. However, striping alone, known as RAID level 0, offers no data protection. Mirroring involves writing identical copies of all data to a pair of physical drives.
8 Note: All of the following numbers are approximations based on 2 channels of 48kHz audio. More audio channels can increase data rates. AJA also provides a freeware application called the AJA Data Rate Calculator that can be used to help determine the amount of storage space and bandwidth requirements needed for a selected format, frame rate, audio setting and compression. The AJA Data Rate Calculator can be found in the AJA Utilities folder which installs in the Applications folder of the Mac OS.

Io HD Installation and Operation Manual — Front Panel Although the default is to show Primary and Secondary formats, you can instead configure the Io HD to show the Primary format on the top line of the display and the currently configured timecode on the second line. If in an input mode, this will display the timecode at input. If set for play out, then the timecode display is what is output. If you see a semi-colon in the timecode display, then it means the timecode is drop-frame.
12 Audio VU LED Indicators These LEDs show the audio signal strength of the selected audio input sources (embedded SDI audio, AES/EBU audio, analog 4-Channel balanced, or 2-Channel unbalanced) or the values for audio being played back during editorial. The LEDs show a standard VU-style display, with the LEDs having the following meanings: Green—audio source signal level is in the “safe” area (no clipping). Vertically, the green LEDs also show the signal strength, so you can see if the signal level is low.
Io HD Installation and Operation Manual — Rear Panel 13 Settings menus (or Easy Setups). While capturing, the selected inputs are mirrored at Io HD’s outputs. When not in the capture mode, outputs change to reflect the output of Final Cut Pro. In all cases, all Io HD’s outputs are active all the time. In other words, the same output video appears simultaneously on the HDMI, SDI, composite, Svideo, and component outputs. (Note: S-video and composite are SD only formats, so they will not output HD material.
14 • 2 channel unbalanced audio outputs (2x RCA) for monitoring. • 4 channel analog balanced audio inputs and outputs. 4x female XLRs are provided for input and 4x male XLRs for output. • IEEE 1394b FireWire™ 800Mbps connector for data between Io HD and Apple Mac. • RS-422 Control Port, 9-pin D-sub, for machine control. • AC power connector with ON/OFF switch, 3 pin (with ground). Each of these groups of connectors are discussed on the following pages.
Io HD Installation and Operation Manual — Rear Panel A Note About YPbPr—Component Video, or YPbPr, has been given several names over time. YUV, Y/R-Y/B-Y, and YCbCr, are just some examples. Although these various formats have some differences in levels, they are all basically the same. Io HD uses the modern YPbPr terminology exclusively. Io HD supports three different types of YPbPr: SMPTE/EBU N10, Betacam (NTSC), and Betacam (NTSC Japan).
16 8 Channel AES/EBU Digital Audio Inputs And Outputs One BNC connector is provided for both the channel 1 and 2 inputs, similarly input channels 3/4, 5/6, and 7/8 are also each grouped on 3 additional BNCs. Another group of 4 BNCs provides the same channel groups for AES/EBU outputs. In order to connect equipment having AES/EBU digital audio XLR connectors, use appropriate adapters (not supplied).
Chapter 3: Getting Started Io HD And Your Workflow There are many possible ways to think about your video/audio workflow. Your workflow setup might be categorized by the end product you produce, whether it be corporate video, professional broadcast media, film work, or desktop video. Or your workflow might be categorized by the type of equipment used rather than the nature of the work produced.
18 Source Deck Type(s) Workflow Attributes Analog Examples: Beta, VHS, and U-matic Digital Examples: Digibeta, DV50, DVCPRO, and DVcam Field or Remote Capture and Editing Capture HD via ProRes 422 with a MacBook Pro Monitoring one of many video/audio sources Examples: monitoring studio equipment or using older legacy equipment in an edit suite Applications Io HD captures and outputs S-video, component video (HD & SD), and composite video, with multi-channel audio Corporate/Industrial Pro Broadcast
Io HD Installation and Operation Manual — Understanding Typical Workflows As quality and codecs improve, the lines between offline and online are blurring. For example, with the DVCPRO HD codec introduced in FCP HD (v.4.5), native HD editing in the codec became possible, providing very high quality results (true HD editing) at low data rates. Compare this to 100MB/sec and higher for uncompressed HD formats, and you can immediately see the benefits.
20 Uncompressed 10-bit 4:2:2 (SD) Data rate: 28 MB/second standard definition—external storage recommended Quality: Excellent, broadcast quality Capturing in an uncompressed format results in clearly defined video, and maintains the full raster size with 4:2:2 chroma sampling. Using an uncompressed format maintains high quality video from the capture stage of the timeline all the way through effects rendering stage.
Io HD Installation and Operation Manual — Workflow General Notes Workflow General Notes The previously discussed codecs are used in different ways based on project characteristics. Some codecs create very high-quality offline files at low data rates for projects that will ultimately be delivered in uncompressed format via an offline/online process. Other projects may use these compressed formats to create final masters.

Choices presented are for US or Japan: 7.5 IRE (NTSC US) 0 IRE (NTSC Japan) Lock Audio Gain To Unity—when set, the Io HD will ignore the Final Cut Pro gain setting and set the audio gain at unity. Not setting this checkbox tells the Io HD to get the audio gain setting from Final Cut Pro.
54 Audio Delay Output: In some cases, monitors such as consumer LCD units, may have video delay inherent in their circuitry. For these monitors, the Audio Delay Output feature may be useful for offsetting the audio to match the video on the monitor. This audio delay feature can also be useful when performing video conversions where video processing can take a frame to occur. Codec Tab Screen This screen offers a variety of controls that determine how the Io HD behaves under Final Cut Pro.
Io HD Installation and Operation Manual — Using The AJA Control Panel Codec Tab Screen Settings Pause On—these two choices determine what happens when Final Cut Pro is paused in stop mode: Full Frame: both fields are displayed resulting in some jitter while paused. Single Field: a single field is displayed, showing no flicker (useful when color correcting or whenever the flickering would be a distraction).
56 AJA Control Panel, Timecode Tab Note: SMPTE 12M-2 is the updated name and specification for what was RP-188. Timecode Tab Screen Settings Input Pulldown Menu —use this pull-down to select the type of timecode you expect to receive at input. The selection will be displayed in the timecode value displayed to the right of the pull-down.
Io HD Installation and Operation Manual — Using The AJA Control Panel User Bits—for monitoring variable frame rate (VFR) timecode (for example, Varicam), you may wish to monitor the user bits embedded in the timecode. If you set this checkbox, Io HD will detect and interpret the user bits and display them next to the checkbox. Output Use QuickTime Timecode—when checked, this directs Io HD to output timecode from the QuickTime timecode track.
58 AJA Control Panel, Timelapse Tab Info Tab Screen This Tabbed screen shows the Io HD software files that have been installed on your system. This information may be needed if you talk to an AJA Customer Service representative to determine if files are missing or need updating.
Io HD Installation and Operation Manual — Using The AJA Control Panel Saving Your Control Panel Presets After configuring the AJA Control Panel via the Tabbed screens, you can then save all your settings as a snapshot for later recall—called a preset. In this way, you can organize the presets for all your typical tasks, saving time by not having to manually reconfigure each time. To save a preset, simply go to “File -> Save Preset...”. Be sure to give the preset a meaningful name.
60 2. AJA Control Panel By “Master”, we mean a process that can control and change what the Io HD is doing and the Primary and Secondary formats that it uses (as set in the Control Panel “Formats” tab screen). QuickTime Application—1st Priority If a running QuickTime application uses Io HD for capture or output, it controls the Primary format via its own menus and settings.
Io HD Installation and Operation Manual — Using Multiple AJA Products The moral of the story: keep the Control Panel visible so you can learn what various QuickTime applications are doing when they control Io HD—and then you can step in and change the application’s settings and Control Panel settings as desired to get the configuration you expect. AJA Control Panel—2nd Priority If a QuickTime application is not running then the AJA Control Panel gets control of the board.
62 would note that it is still uses the KONA 3 for its input/output. Note that some applications, like AJA TV, have a provision for playing in the background, so playback on one product could even continue when switching the targeted device for use with another application. You can even feed the output from one AJA product to another AJA product on the same system in such cases.
Io HD Installation and Operation Manual — Easy Setups for Typical Uses 1 Click on the Easy Setups menu item and Final Cut Pro will present the Easy Setup dialog window: Easy Setup Dialog In the Easy Setup dialog, the Format, Rate and the currently selected Easy Setup in the Use pulldown is shown.
