case, all ports (both A and B) share the same internal FireWire bus. So plan accordingly for your FireWire resources. In addition, keep in mind that if you connect a FireWire A device, it can slow the entire bus to whenever the device is active on the bus, so any connected FireWire B devices may not be able to operate at their full performance levels at all times. (If the FireWire A device is not active, however, it won’t affect the bus.
CONNECT VIDEO INPUTS AND OUTPUTS The V4HD provides a wealth of video input and output connectivity, from consumer analog formats such as S-video and composite to broadcast formats such as HD-SDI.
YPbPr or RGB The V4HD SD and HD component input and output sections support YPbPr or RGB operation, as shown by the color legend on the rear panel. Pr/R Y/G Pb/B Pr/R Y/G Pb/B Legend Figure 3-3: The V4HD supports both RGB and YPbPr component video. Each of the four banks (SD in, SD out, HD in and HD out) can be independently configured for either RGB or YPbPr operation. This setting is made in the MOTU Video Setup software. For the component inputs, see “Video Source menu” on page 44.
EXAMPLE V4HD VIDEO CONNECTIONS and match HD and SD sources and destinations, connect them all, and then choose the desired source from the MOTU Video Setup software. Here is an example of the types of video devices that you can connect to the V4HD.
CONNECT AUDIO INPUTS AND OUTPUTS The V4HD provides 32 channels of simultaneous audio input and output (Figure 3-5), grouped in four banks of eight channels each: analog, AES/EBU, optical and embedded (for SDI and HDMI out). For connecting the first three banks, see the following sections. For embedded, make the SDI and/or HDMI connections as described earlier and then enable embedded audio. See “SDI Input and SDI/HDMI Output” on page 75.
AES/EBU digital audio I/O The V4HD provides eight channels of 24-bit AES/EBU digital audio input and output at standard sample rates from 44.1 kHz up to 96 kHz. 4-channel vs. 8-channel operation As shown in Figure 3-5, the AES/EBU section supplies four XLR connectors directly on the rear panel. These input and output jacks provide four channels each of AES/EBU digital input and output via direct connection to the V4HD rear panel using standard AES/EBU-grade cables.
When operating the optical ports at a 2x sample rate, be sure to choose either Type I or Type II operation, as explained in “ADAT Type” on page 99. Synchronization and sample rate conversion When making optical digital audio transfers to and from the V4HD, the two devices must be synchronized with one another, or you must employ the V4HD’s sample rate conversion. See “Syncing digital audio devices” on page 29.
VIDEO SYNC CONNECTIONS AUDIO WORD CLOCK Connect a video sync source, such as blackburst, to the VIDEO REF IN jack (Figure 3-9). This input accepts either a Bi-level (SD) sync source or a Tri-level (HD) sync source. The V4HD can resolve to a VIDEO REF IN signal only when it is in Playback mode. When it is in Capture or Convert mode, it genlocks to the current video source. For further information, see “Playback Clock Source” on page 53.
To resolve another device to the V4HD (even when video is enabled), connect the V4HD’s WORD OUT jack to the word clock input on the other device (Figure 3-12). Master V4HD Word clock OUT Word clock IN Slave Forcing a 1x word out rate When the V4HD is operating at a 2x or 4x sample rate, it can generate a word clock output signal that either matches the current system clock rate (any rate between 88.2 and 192kHz) or the corresponding 1x rate.
SYNCING DIGITAL AUDIO DEVICES Master If you would like to transfer audio digitally between the V4HD and another device that has AES/EBU or ADAT optical digital I/O, there are three basic scenarios in which the V4HD could make a digital audio transfer: The V4HD video features are enabled and it is therefore resolved to its video clock. ■ ■ The V4HD video features are disabled, and you are running the V4HD as an audio interface (see “Audio only” on page 39).
Resolving a digital mixer to the V4HD If the V4HD is currently operating as a video interface (i.e. Audio only mode is not enabled), and you would like to connect a digital mixer via ADAT optical or AES/EBU (or both), resolve the digital mixer to the V4HD, either via its optical or AES/EBU connection, or via word clock, similar to what is shown in Figure 3-17.
If you choose the other device, such as a digital mixer, as the clock master, resolve the V4HD to it via word clock in, AES/EBU in or ADAT optical in, as demonstrated below in Figure 3-18. Master Sample rate conversion The V4HD is equipped with one 8-channel bank of real-time sample rate conversion that can be assigned to any individual input or output bank using the “Sample Rate Convert” software option (page 75). This feature provides a great deal of flexibility in making digital transfers.

Part 2 Video Operation
CHAPTER 5 V4HD Basics ONE INPUT TO ALL OUTPUTS The basic design concept of the V4HD is that you choose a video input and the V4HD sends the signal to all outputs, converting the signal where necessary to conform to the output format, regardless of the input signal format. Most common conversions are supported, although not all. In those few cases, the corresponding output does not produce a signal.
Capture The V4HD is in Capture mode when it is connected to the computer and video software has actively taken control of the V4HD hardware for the purposes of capturing video and audio from the V4HD via the FireWire connection. Here are some examples of when video software would put the V4HD into Capture mode: ■ You open the Log and Capture window in Final Cut Pro. Or you use any Final Cut Pro feature, such as Edit to Tape, that involves capturing or previewing the live video input from the V4HD.
The Playback Only (disable inputs) option in the MOTU Video Setup software Setup tab (Figure 6-19 on page 48) lets you force the V4HD to stay in playback mode. Playback Only mode is useful when you are at a point in your workflow where you are not doing any capturing. For example, you may have no inputs connected to the V4HD hardware, or you may have inputs connected, but you are not currently using them.

SIGNAL PATH DIAGRAM The Signal Path Diagram (Figure 6-2, Figure 6-3) lets you view and control the V4HD’s hardwarebased video conversion features and signal flow settings.
Playback settings menu The Playback Settings menu (Figure 6-2) lets you choose one of four sets of playback settings to view in the signal path diagram. There are separate settings for 480, 576, 720 and 1080 playback (Figure 6-4). When you choose a format from this menu, the settings for the format are displayed in the Playback Signal Path diagram. When Final Cut Pro is running, this menu becomes inactive and simply displays the Final Cut Pro timeline format and frame rate.
Video Source menu The Video Source menu (Figure 6-3) is important because this is where you choose the video input from which the V4HD will convert and capture. Choose any SD or HD source (Figure 6-5), and the V4HD converts it to all output formats and sends it over Firewire to the computer. Letterbox (HD to SD) Letterboxing is the standard practice of conforming widescreen film images such as film or HD to an SD video frame while preserving the original aspect ratio.
Full Screen (HD to SD) The Full Screen option (Figure 6-6) also preserves the aspect ratio of the HD image but scales it proportionally to fill the full height of the SD frame (Figure 6-9). As a result, the portions of the HD image that fall outside the frame (along the lefthand and right-hand edges) are cropped. But the full height of the SD frame is used.
fill the unused portion of the frame on either side (Figure 6-13). No cropping occurs and the full image is preserved. 14:9 Pillar Box (SD to HD) With the 14:9 Pillar Box option (Figure 6-12), aspect ratio is preserved (Figure 6-14) and some cropping occurs on the top and bottom edge, but not as much as in Full Screen mode (explained below). In addition, the pillar box bars are smaller.
The V4HD’s HDMI/DVI output can send either the SD or HD video signal. Use the “HDMI Output Source” setting (page 51) in the Output tab to specify either SD or HD. If you choose HD, the HDMI/DVI block in the signal path diagram connects to the HD signal path, as shown in Figure 6-3. If you choose SD, it connects to the SD signal path, as shown in Figure 6-25. FireWire Your host software running on the computer is represented by the block labeled with the FireWire icon (Figure 6-3).
TABBED SETTINGS Use the tabs (Figure 6-1) to view settings for each tab in the lower right area of the window. Each tab is discussed in the following sections. SETUP The Setup tab (Figure 6-19) has the following settings. Auto Detect Input Format The Auto Detect Input Format option (Figure 6-19) lets you choose the degree to which the V4HD will automatically detect the video format for the input currently chosen in the Video Source menu (Figure 6-3).
1080PsF29.97 input. The signals are identical but will be interpreted differently by the V4HD’s down converter, so in a case like this, you can choose Genlock and then specify the incoming format manually in the HD and SD Output Format menus (Figure 6-3), as explained in “SD/HD output format” on page 46. Format and Genlock The Format and Genlock option (Figure 6-19) causes the V4HD to fully detect both genlock and the video format for the current video source.
480i Setup The 480i Setup option (Figure 6-19) lets you choose between USA (7.5%) and Japan (0.0%) for NTSC composite and S-video input and output. also allows you to resolve the V4HD to another digital audio device via its word clock input, AES/ EBU input or ADAT optical input. See “Syncing digital audio devices” on page 29. Timecode Destination The Timecode Destination menu (Figure 6-19) lets you specify the video destination for timecode generated or regenerated by the V4HD.
OUTPUT The Output tab (Figure 6-22) provides settings for the V4HD video outputs. 480i Broadcast Legalizer Video with highly saturated colors may result in a composite signal which is too “hot” to broadcast. The 480i Broadcast Legalizer menu (Figure 6-22, Figure 6-23) controls the V4HD’s SD Broadcast Legalizer module, which desaturates any overly saturated pixels to bring the composite signal within the specified limit. For example, selecting 120 IRE guarantees the output will never exceed 120 IRE units.
PREVIEW The Preview tab (Figure 6-26) lets you preview the video signal being received from the currently selected input in the Video Source menu (Figure 6-3). Choose the desired Preview Format (SD or HD) from the menu provided. If up conversion or down conversion is being applied, the “Format Conversion menu” on page 44 determines how the signal is formatted within the preview frame.
PLAYBACK The Playback tab (Figure 6-27) provides settings that apply to video playback from Final Cut Pro (as opposed to capturing). Therefore, these settings relate to the current settings in Final Cut and its timeline. Internal Choose Internal (Figure 6-28) to make the V4HD resolve to its own internal clock. This setting is best when you do not need to resolve the V4HD to house sync (blackburst).
Playback 29.97 fps Timecode If your Final Cut Pro time line is currently set to the 29.97 drop-frame format, choose Drop Frame from the Playback 29.97 fps Timecode menu (Figure 6-27) so that the V4HD matches Final Cut’s frame format. If Final Cut is running 29.97 non-drop, choose Non-Drop Frame. (If you are running Final Cut at any other frame rate besides 29.97, this setting is ignored.
None/Weave The None/Weave option (Figure 6-30) is the simplest algorithm, with no processing or advanced frame/field detection. Instead, it “weaves” each pair of fields together, treating them as a progressive frame. This option is best for material that shouldn’t really be treated as interlaced, such as SD footage shot in nonstandard, progressive recording modes, such as the“30p” mode found on some cameras.
MOTU VIDEO SETUP
CHAPTER 7 Final Cut Pro OVERVIEW BEFORE YOU LAUNCH FINAL CUT PRO The V4HD serves as a powerful video capture and playback device for Apple Final Cut Pro. Operation is straightforward and follows the general workflow prescribed by Final Cut Pro. In addition to standard log and capture procedures and straightforward timeline playback, the V4HD also provides presets for Easy Setup, Sequences, Capture and Device Control.
EASY SETUPS FINAL CUT PRO AUDIO/VIDEO SETTINGS There are five settings in Final Cut Pro that directly impact V4HD operation: To set up Final Cut Pro manually, without using an Easy Setup, or to adjust the settings for an Easy Setup, simply go to Final Cut Pro’s Audio/Video Settings window (Figure 7-2) and individually select the V4HD’s capture, device control and sequence presets. The V4HD presets are identified by either V4HD or MOTU in their name.
CHOOSING A WORKFLOW The V4HD supports a range of SD and HD workflows, summarized in Figure 7-3 below. The V4HD supports every workflow via FireWire 400 or 800, although Apple ProRes 422 HQ should be used with a FireWire 800 connection whenever possible. For uncompressed SD, all DVCPro formats and Apple ProRes, the V4HD provides sequence and capture presets for all supported format/frame rate/codec combinations. Other codecs require that you make your own custom sequence settings.
Other codecs The V4HD provides hardware-assisted capture and playback over FireWire 400 or 800 for any HD codec supported by Final Cut Pro. The V4HD is optimized for codecs that are similar in nature to ProRes HQ (around a 6:1 compression ratio or higher).
your sequence. When Final Cut Pro is running, this menu cannot be changed, as the playback format is specified by your settings in Final Cut Pro. In the Playback tab, make sure the Playback Timecode Offset and frame rate match your Final Cut Pro sequence offset and frame rate. If you are working with drop frame time code, be sure to choose Drop frame from the Playback 29.97 fps Timecode menu (Figure 6-27 on page 53).
When you are capturing Apple ProRes 422, Final Cut Pro performs the encoding in real time during capture. Given today’s Intel processor speeds, ProRes requires approximately one Intel CPU core to perform this task, depending on the ProRes quality mode (standard or HQ), the speed of the processors, and other related factors. Your performance will vary, but generally speaking, ProRes 422 standard quality capture requires a computer with at least two Intel core processors; four cores or more are recommended.
codec you have chosen, core processor speeds, etc. If you have a four- or eight-core machine, however, you should be able to play back just about any video format you wish. HARDWARE CONVERSION DURING CAPTURE OR PLAYBACK The V4HD provides hardware-based conversion features, which you can employ during capture or playback in Final Cut Pro. Here are a few examples: ■ During log and capture, you could up-convert SD to HD in the V4HD hardware and then capture it in Final Cut Pro as HD.
Conversions that are not supported If the menus in the Playback Signal Path and Capture Signal Path diagrams don’t provide the format you are looking for, it means that this form of conversion either doesn’t apply, or it is not supported by the V4HD video conversion hardware.
This is the order in which the banks appear in MOTU Audio Setup: Figure 7-8: The top to bottom order of the audio banks listed in MOTU Audio Setup is how they are ordered in Final Cut Pro. Figure 7-9: Clip Settings tab. In the above example (Figure 7-8), the analog and SDI banks are enabled. This means that the V4HD will supply 16 channels of audio input and output to Final Cut Pro. Channels 1-8 are the analog ins and outs; channels 9-16 are the SDI ins and outs.
■ Chapter 9, “CueMix FX” (page 79) for complete information about controlling CueMix monitoring ■ “Sync CueMix audio with video output” on page 77 and “Additional Audio Delay” on page 76 for details about managing audio latency for CueMix monitoring AUDIO PLAYBACK To play back audio: 1 Choose View menu> Audio Playback> V4HD. 2 In the Sequences window, select your sequence. 3 Choose Sequence menu> Settings. 4 Click the Audio Outputs tab and configure the outputs as needed.
4 Back in Final Cut Pro, choose the device control preset that best suits your project and device. This setting can be accessed in the Audio/Video Settings window (Final Cut Pro menu) or in the Capture Settings tab in the Log and Capture window. You can now use Final Cut Pro’s transport features to control your deck. Consult the Final Cut Pro documentation for complete information about using machine control during capture, edit to tape and print to video operations.

V4HD tab settings The V4HD tab (Figure 8-1) provides settings that apply to a specific V4HD interface. If you have MOTU audio interfaces connected to your computer in addition to the V4HD, you’ll see a separate tab for each interface. General tab settings The General tab (Figure 8-1) provides settings that apply globally to all connected MOTU interfaces. Figure 8-1: MOTU Audio Setup gives you access to all of the audio settings in the V4HD hardware.
V4HD TAB SETTINGS Sample Rate Choose the desired Sample Rate for recording and playback. The V4HD can operate at 44.1 (the standard rate for compact disc audio), 48, 88.2, 96, 176.4 or 192 kHz. Make absolutely sure that all of the devices connected digitally to the V4HD match the V4HD’s sample rate. ☛ Mismatched sample rates cause distortion and crackling. If you hear this sort of thing, check the sample rate settings in your hardware and here in MOTU Audio Setup. Operation at 4x sample rates (176.
V4HD to slave to an external word clock source, such as the word clock output from a digital mixer or a digital audio interface. AES/EBU The AES/EBU clock source settings refer to the AES/EBU input pairs on the V4HD. This setting allows the V4HD to slave to another device connected to one of the V4HD’s four AES/EBU input pairs when video is disabled (see “Enable Video” on page 50). Use this setting whenever you are recording input from a DAT deck or other AES/EBU audio device into the V4HD.
The Default Stereo Input and Default Stereo Output settings in MOTU Audio Setup (Figure 8-1 on page 72) let you specify the stereo input and output on the V4HD to be used when it is chosen as the audio I/O device in the system preferences. explained below. The options in the menu change, depending on the V4HD’s current Sample Rate setting (page 73). For example, if the V4HD is currently set to 192 kHz, you’ll see “x 4” and “÷ 4” settings that don’t apply to the lower sample rates.
x4/÷4 Choose one of these sample rate conversion options when the rate for the chosen digital I/O bank needs to be four times the V4HD system clock rate or one quarter of the system clock rate. Either way, the digital I/O bank remains resolved to the V4HD system clock. ADAT In 44.1/48 versus ADAT In 88.2/96 The V4HD provides two sets of ADAT optical digital I/O connectors, which together provide 8 channels at 44.1 or 48 kHz or 8 channels at 88.2 or 96 kHz.
connected to the V4HD’s analog audio outputs. Even though audio and video depart the V4HD outputs completely in sync with one another, the image on the plasma will be running one frame behind the audio you hear from the studio monitors. Use the Additional Audio Delay option (Figure 8-1) to delay the V4HD’s audio output by one frame to match the image on the plasma. So, if the V4HD’s CueMix audio doesn’t sound in sync with the current video signal being monitored, try checking this option.
Figure 8-4: The Edit Channel Names window.
CHAPTER 9 CueMix FX OVERVIEW CueMix FX provides access to the flexible audio mixing and monitoring features of the V4HD, which are fully functional under video operation (capture, convert and playback) and the V4HD’s audio only mode. CueMix lets you route any combination of audio inputs to any stereo output pair. CueMix allows you to set up a separate mix configuration for every stereo output pair on the V4HD — a total of 16 stereo buses (or 4 stereo busses at 176.4 or 192 kHz).
CUEMIX MONITORING BENEFITS CueMix FX provides several major benefits to your video post-production workflow: CueMix has no buffer latency. Thanks to the V4HD’s hardware-based mixing, CueMix provides the same throughput performance as a digital mixer, so you can monitor audio as well as video during log and capture. ■ ■ CueMix imposes absolutely no processor drain on the computer’s CPU. ■ CueMix routing can be maintained independently of individual software applications or projects.
Master mute The master mute button (Figure 9-1) temporarily disables (silences) the mix. Output level meter The Output level meter (Figure 9-1) shows you the output for the mix’s physical output, which may include audio from your host audio software. The clip indicators clear themselves after a few seconds. Input section The channel strips to the left of the master fader represent each input in your V4HD. Use the input scroll bar (Figure 9-1) to view additional inputs.

MOTU SMPTE SETUP The included MOTU SMPTE Setup™ software provides a complete set of tools to generate SMPTE for striping, regenerating or slaving other devices to the computer when the V4HD is operating in Audio Only mode (see “Enable Video” on page 50).
Address The Address light glows continuously when the V4HD has successfully achieved lockup to SMPTE time code. Freewheel The Freewheel light illuminates when the V4HD is freewheeling address (time code), clock or both. For details about Freewheeling, see “Freewheel Address” and “Freewheel clock” below. SMPTE source Choose SMPTE, or the analog input to which the SMPTE time code source is connected. This is the input that the V4HD “listens” to for time code.
Stripe Click this button to start or stop time code. To set the start time, click directly on the SMPTE time code display in the Generator section and type in the desired start time. Or drag vertically on the numbers. Click here to edit the start time, or drag vertically on the numbers. Figure 10-2: Setting the time code start time. Regenerate This option, when enabled, causes the generator to generate time code whenever the V4HD is receiving SMPTE time code.

STANDALONE VIDEO CONVERSION AUDIO ONLY MODE The V4HD provides hardware-based conversion features, which you can employ during standalone operation. Here are a few examples: To put the V4HD into Audio only mode: ■ You could up-convert SD to HD in the V4HD hardware and then distribute it to all HD outputs. Or you could down-convert HD to SD and distribute it to all SD outputs. You could connect a 23.976 fps input signal, insert pull-down to 29.97 fps and send this signal to all SD and HD outputs.
CHAPTER 12 Front Panel LCD Programming OVERVIEW The V4HD is the first FireWire video interface to offer complete front-panel programming via a 2x16 backlit LCD display. Almost all V4HD settings can be accessed via these front-panel controls.

VIDEO STATUS The VIDEO STATUS section (Figure 12-1) provides quick feedback regarding the V4HD’s current video operation. It is divided into the following banks of LEDs: MODE, SIGNAL, FORMAT, RATE and Genlock (Figure 12-2): SIGNAL The LEDs in the SIGNAL bank (Figure 12-2) represent the various video inputs and outputs on the V4HD. FireWire is viewed as another input or output, depending on whether the V4HD is capturing or playing back.
RATE The LEDs in the RATE bank (Figure 12-2) indicate the frame rate for the currently selected signal in the SIGNAL bank. GENLOCK The LEDs in the Genlock bank (Figure 12-2) indicate the input format to which the V4HD has successfully achieved genlock. It also indicates the format for the currently selected output in the SIGNAL bank. If you are viewing all formats in the SIGNAL bank (Figure 12-3), the Genlock bank will display the SD and HD formats that the V4HD is genlocking to and generating.
value chosen will flash. Push the VALUE knob to confirm your choice; the newly chosen value will stop flashing. Video Source This is the setting described in “Video Source menu” on page 44. The PHONES knob The PHONES knob lets you control the volume of either the headphone jack or the outputs on the rear panel that you have designated as the main outs (see “Main Volume Ctl (Control)” on page 102). Press the knob to toggle between the headphones and the main outs.
AUDIO MENU Press the MENU button repeatedly to access the Audio menu. The Audio menu gives you access to the many audio-related settings in the V4HD, as described briefly below.

Part 5 Appendices
APPENDIX A Troubleshooting I see the following error message in Final Cut Pro: Unable to locate external device. Why? If you see the error message below when operating the V4HD with Final Cut Pro, it means that Final Cut Pro has lost communication with the V4HD hardware. Check your V4HD hardware and cable connections. ■ Unplug your FireWire A connection to the computer and switch to a FireWire B connection.
My reference monitor(s) connected to the V4HD does not output any video. Make sure the Final Cut Pro MOTU RT Enabler is properly installed in Library\Application Support\Final Cut Pro System Support\Plugins. I’m not seeing any SD output. Why? SD output is disabled when the HD frame rate is set to 24, 30, or 60 (as opposed to 23.976, 29.97, or 59.94). Check the HD frame rate. I can’t get any video input or output at all. Why? The V4HD’s video features can be temporarily disabled.
