  9. 9. Io Chapter 1: Introduction Overview AJA Io brings a wide variety of high quality video and audio to an Apple Power Mac running Final Cut Pro 4 software. Offering unsurpassed 10-bit uncompressed video and multi-channel audio, Io allows a Power Mac to be configured anywhere from a professional editing suite, corporate/industrial video center, or high-powered desktop video setup—and just about anything in between. Both analog and digital sources are offered, allowing connection to just about every kind of video/audio peripheral from the most current digital decks to old legacy devices. It does this with unique simplicity, using a single FireWire connection between Io and the Apple Power Mac—while serving simultaneous realtime connection for all audio and video sources. How does Io transfer uncompressed video over FireWire? It efficiently uses the IEEE 1394a 400Mb/s FireWire port on the Power Mac for all data transfer— since uncompressed is only 270Mb/s (and it has filler data included), FireWire can easily handle the bandwidth. In addition to all the video and audio connections, Io also provides the following professional features: • A/V presets for Final Cut Pro 4.n • RS422 machine control for professional control of VTRs • Audio word clock for synchronization • Video Genlock for synchronizing with reference sources 11 1

However, to ensure performance and quality, the disk storage system used with the Apple Power Mac must be able to meet the demands1of storing realtime uncompressed media. At the very minimum, the disk storage system must be able to provide and maintain a consistent 50 MB/s transfer rate from the Power Mac to disk (read/write). There are a variety of system configurations and peripherals that can provide this level of performance. Possible system configurations are listed below: Storage Method Features/Limitations Cost Xserve RAID Features up to 14 ATA/100 Expensive, although drive channels, dual the cost per independent RAID controllers, gigabyte is excellent and a dual 2Gb Fibre Channel when large storage host interface. Xserve provides is needed up to 2.5TB of storage with throughput of up to 400 megabytes per second. External ATA/IDE or SCSI Scalable. Performance almost Moderately RAID as good as Xserve, although it Expensive can be more complex to set up and maintain. Many vendors offer solutions (too many to list here; check with your Apple dealer for SCSI Storage solutions for details). Although the connection to the external RAID chassis is SCSI, the drives themselves may be SCSI or ATA. A pure SCSI array will offer higher performance at a higher cost. Note: FireWire drive solutions are not supported in use with AJA Io. Since Io connects to the host Power Mac via FireWire and uses the FireWire bus bandwidth extensively, it cannot also be used for storage—at the same time. You can however attach and use FireWire drives on the Power Mac whenever Final Cut Pro is not in use. Their presence on the bus will not affect Io performance as long as they aren’t being actively used.

  15. 15. Io Installation and Operation Manual — System Requirements 7 About RAIDs Redundant Array of Independent Disks, or RAID, is a group of hard drives that appears to the host Power Mac as a single high-speed storage unit. RAID systems enable you to increase storage capacity and get the performance, reliability, and data protection needed for video production, but not possible from a single hard drive. RAID drives inside the array operate simultaneously, increasing overall throughput. RAID technology is comprised of these techniques (some or all): • Striping data across multiple drives for storage performance (RAID 0). • Mirroring for redundancy (RAID 1). • Parity for data protection (RAID 5 [plus others]). 1 Most RAID configurations, or RAID levels, combine these to provide a balance of protection and performance. 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. This results in very high data reliability: If one drive fails, the data is still available on the remaining disk drive. However, it also results in a storage efficiency of only 50 percent, because two physical drives are required to achieve a single drive’s capacity. Mirroring alone is known as RAID level 1. Parity provides data protection without requiring complete duplication of the drive contents. In the event of a drive failure, parity information can be used with data on surviving drives to reconstruct the contents of a failed drive. Parity data can be stored on a dedicated drive, as in RAID 3, or distributed across an array of drives, as in RAID 5. Parity provides much greater storage efficiency than mirroring—up to 85 percent for a set of seven drives. Software For Striping AJA recommends the Disk Utility software provided by Apple with OS X for creating and striping RAIDs, including 3rd-party, SCSI, and Xserve RAIDs. It is very easy to use and has been tested to work well. The utility can be found in Macintosh HD/ Applications/Utilities, where “Macintosh HD” is the name of the system drive. AJA Io and Xserve RAID For the optimum in disk storage with Final Cut Pro 4 and AJA Io, we recommend Apple’s Xserve RAID. Xserve RAID holds up to 14 hot-swap Apple Drive Modules— 2.5TB of storage—in a rack-optimized 3U enclosure. Each 7200-RPM hard drive connects to a dedicated ATA/100 drive channel, eliminating a traditional source of bottlenecks and maximizing the 2Gb/s Fibre Channel host connection(s). By adding more Xserve RAID systems, you’ll have very large expansion capabilities: A standard 42U rack can hold over 35TB of Xserve RAID storage.
  16. 16. 8 Xserve RAID is designed for nonstop operation. Redundant hot-swap power and cooling modules allow the system to keep functioning even if one module fails. A high-availability architecture and dual independent RAID controllers support RAID levels 0, 1, 3, 5, and 0+1. In addition, Xserve RAID supports hybrid RAID levels 10, 30, and 50 when used in conjunction with host-based software RAID. Remote Xserve RAID management capabilities are provided via Apple’s Java-based RAID Admin application. Note: When creating and striping an Xserve RAID for Io using the Apple Disk Utility provided with OS X, use RAID 50: in other words, the internal Xserve RAID drives are set up as RAID 5; the Xserve RAID then shows up in Disk Utility as two drives (regardless of the number of internal drives) which must be configured together as RAID 0. Apple calls this configuration “RAID 50.” Storage capacity No matter which storage system you choose, pick one that can scale to meet your needs over time. Ideally, you should be able to increase storage capacity or switch to a RAID level offering increased data protection in the future. Balance current and future storage needs with your budget and choose accordingly.

In the Outputs capture mode, Io’s inputs are selected by Final Cut Pro’s Audio Video Settings menus (or Easy Setups). While capturing, the selected inputs are mirrored at Io’s outputs. When not in the capture mode, Io’s outputs change to reflect the output of Final Cut Pro. In all cases, all Io’s outputs are active all the time. In other words, the same output video appears simultaneously on the Composite, S-Video, Component, and SDI outputs. This method of operation allows simultaneous connection to VTRs and monitoring facilities.
  23. 23. Io Installation and Operation Manual — Rear Panel 15 About BNC Although most video professionals are used to BNC connectors, you may not have Connectors seen them if you’ve been using primarily desktop video equipment. BNC connectors ensure a positive connection by the act of locking the connectors together via pins in one connector that fit into slots in the corresponding connector. To make a BNC connection, slide the cable connector over the connector on the Io rear panel and then when seated, rotate the barrel of the cable connector 90˚ clockwise until the connectors are locked together. When properly locked, the cable cannot accidentally be pulled out. Pins (2) on BNC Connector (connector on Io Rear Panel) 1 Align slots in cable connector barrel with connector pins, then slide it over the pins and rotate the barrel to lock the connectors together Connectors Connectors on the rear panel are arranged in groups for easy installation and maintenance. Connectors provided are: • 4 channel AES/EBU audio inputs (2 XLRs) and outputs (2 XLRs). • 4 channel balanced/unbalanced analog audio In connectors support XLR or TRS-type connections. 4 channel balanced analog audio Out connectors are XLR. • 8 channel ADAT audio In/Out. Connectors are optical TOSLINK. • 8 channel TASCAM-style balanced audio monitor Out is a DB25 connector. • Audio word clock connector (BNC) for audio synchronization (optional) • RS-422 Control Port (Sony), 9-pin D, for machine control. • IEEE 1394a FireWire connector for audio/video and control data between Io and Apple Power Mac. • SDI video with embedded audio In/Out • S-Video In/Out (Y/C), one 4-pin mini-DIN for input, and one 4-pin mini-DIN for output. • Composite NTSC/PAL Video In/Out, 1 BNC for input, and 1 BNC for output. • Component YPbPr/RGB Video, 3 BNCs for input, and 3 BNCs for output.

  25. 25. Io Installation and Operation Manual — Rear Panel 17 Audio Word Clock An Audio Word Clock connector (BNC) Audio Word Clock provides audio synchronization with external audio/video systems. It works much the same as a genlock, providing a standard signal to Out lock with. The Audio Word Clock output can be used to keep sync for any external DAT, digital mixer, signal processor, A/D or D/A converter, or audio workstation that accepts Audio Word Clock. RS422 Machine Control A female DB9 connector provides 1 connection for VTRs, camcorders, disk media servers, and other devices using RS422 SMPTE (Sony) protocol. RS-422 FireWire IEEE 1394a FireWire connector for connecting to the 400 Mb/s FireWire connector on an Apple Power Mac for passing video, audio, and control data. Software installed from the Io Installer CD provides the Power Mac with drivers that allow optimum use of Io from within Final Cut Pro. This connector does not support connection to any other FireWire devices. SDI Input and Outputs In Out 1 BNC connectors are provided for one SDI input, two SDI outputs (independent of the input), and one looping SDI output that follows the input. SDI inputs and outputs SDI support video and embedded 24-bit digital audio. Use SDI wherever possible for the best quality 10-bit uncompressed video input, Loop Out Out 2 capture and output. If peripheral equipment has a variety of inputs/outputs, look to see if it has SDI I/O, and use it where possible. Most high-end professional broadcast equipment supports SDI (VTRs, cameras, media storage servers, etc.). S-Video (Y/C) In S-Video input and output female 4-pin mini- DINs provide for connection of desktop video/pro-sumer level equipment, including S-Video camcorders, VCRs/VTRs, and monitors—to name a few. Use high quality shielded S- Video cables when making connections. S- video signals are converted internally to 10- Out bit digital.
  26. 26. 18 Composite NTSC/PAL In BNC connectors support composite NTSC or PAL input and output. Connect an NTSC or PAL composite video cable from Composite a VTR, Camera, or other source to the Composite In BNC. Then connect the Composite Out BNC to a monitor, or other Composite video device. Composite Out video signals are A/D (input) and D/A (output) converted (10-bit). YPbPr Pr/R In Y/G In Pb/B In Connect component YPbPr video cables from a VTR, Camera, or other source to the three YPbPr input BNCs: Y/G, Pr/R, Component and Pb/B. Then connect the YPbPr Out BNCs to a monitor, or other component device. Component video signals are A/D (input) and D/A (output) converted (10- Pr/R Out Y/G Out Pb/B Out bit). Component video signals are generally higher quality than composite, but not as high quality as serial digital (SDI). A Note About RGB—Although RGB is used less in today’s video systems, Io supports it at both input and output. Because Io’s (and SMPTE SDI’s) native format is YPbPr, AJA recommends the use of YPbPr whenever possible. Although component video monitors often have RGB inputs, it’s better to use YPbPr when the monitor supports it. The YPbPr format provides “headroom” for “superwhite” and “superblack”—and these video levels will be clipped when transcoding to RGB. Also, the RGB/YPbPr transcoding involves a level translation that results in mathematical roundoff error. Within Final Cut Pro, RGB can be configured in the Audio/Video Settings or Easy Setups menus. 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 uses the modern YPbPr terminology exclusively. Io supports three different types of YPbPr: SMPTE/EBU N10, Betacam (NTSC), and Betacam (NTSC Japan). These three formats differ in level only and are configured in Final Cut Pro within the Audio/Video Settings or Easy Setups menus. Reference Video (looping) Loop These two BNC connectors allow you to synchronize Io outputs to your house reference video signal (or black burst). If Ref you have a sync generator or central piece of video equipment to use for synchronizing other video equipment in your studio, then connect its composite Loop output here. When Io outputs video it uses this reference signal to lock to.

Io Installation and Operation Manual — Rear Panel 19 AC Power 100 - 240V~ 50/60Hz 0.3A A standard male AC power socket provides connection to power cable (supplied separately) having three wires—one for ground. The internal Io power supply is autosensing, meaning that it adjust automatically to either 110 or 220 VAC. The range of input AC levels is from 100 to 240VAC at either 50 or 60Hz. A power switch is part of the connector, allowing operator power ON/OFF. 1 Caution: The Io chassis has no user-serviceable parts. An internal fuse protects the circuitry; however, it can only be replaced by AJA service centers or AJA dealers.

This chapter hopes to show how Final Cut Pro and Io can help fit into whatever workflow you currently have and make it more efficient. If you’re doing anything beyond standard DV direct into a Power Mac, then Io will make work easier. Even if you have been using DV direct to a Power Mac, Io will vastly increase what you can capture and bring into Final Cut Pro. A Workflow Scenarios diagram on the following page shows types of equipment, sorted by VTR source, and the types of workflow attributes and Io applications supported. After the diagram, we also discuss some typical applications. 31 1
