Frequently Asked Questions about Mbox software and hardware.
If you have questions or comments, or have items that you would like to see added to the FAQs, please email email@example.com.
Licensing & Installation
Q - I own a USB license key (dongle) for Mbox Designer/Studio/Mini v3 and I would like to upgrade to v4. What do I do?
A - You should contact an account executive at your local PRG office to purchase an upgrade. Alternately, please contact firstname.lastname@example.org and we can help you find an account executive to process the upgrade sale.
Q - I have a soft-license for Mbox Studio/Mini v3 and I would like to upgrade to v4. What do I do?
A - Please contact email@example.com and we can help you with your upgrade sale.
Q - I heard that you have changed to a new soft-license scheme (QLM) for Mbox Studio/Mini/Player and I have the old scheme (EWS/eSellerate). Do I need to do anything?
A - Existing EWS soft-licenses will continue to work, though our ability to manage these licenses is limited. If you have issues with an EWS soft-license, please contact firstname.lastname@example.org
Q - I bought a soft-license for Mbox Studio/Mini/Player online and I’ve entered the serial number correctly, but it won’t activate the license.
A - Sometimes the EWS and QLM systems are a little slow so you may have to wait a little longer for the purchased serial number to work through their online validation. If the problem persists, please contact email@example.com.
Q - Why does Mbox Daemon say it cannot run because the runtime environment is not correctly installed?
A - The Mbox application installer should properly set this up. However if the necessary folders are missing or the permissions on the folders are incorrect then Daemon cannot run. Try reinstalling the Mbox software using the appropriate installer. Please contact firstname.lastname@example.org for assistance.
Q - I’ve bought a USB license key (dongle) what do I need to do to get it to work?
A - In order to use the USB dongle a driver must be installed. When you install the Mbox software, a script is placed in the '/Applications/Mbox Utilities/Mbox Dongle Drivers' folder that can be run to install or upgrade the necessary driver. Alternately, standalone driver installers can be downloaded using the links at the bottom of the main Mbox page. Make sure to download the correct version for your macOS installation!
Q - Why do I get an error message when I try to install or open Mbox/Director/Remote/etc. that says the installer/app can’t be opened because it was not downloaded from the App Store?
A - The Gatekeeper functionality in macOS limits what apps can be installed and run on the computer. You can change the Gatekeeper limits to allow the install and launch of applications that aren't from the App Store. Gatekeeper settings can be found in System Preferences > Security & Privacy > General. Mbox v3.9 and above provide proper code-signing for the entire Mbox suite of applications so this preference can be set to “Mac App Store and identified developers.”
Computer Specification (Mac & OS)
Q - What Mac computer should I buy to use with Mbox?
A - The better the overall performance of the computer, the better it will work for Mbox. It should be a 64-bit CPU with at least 4 cores (more is better). Always opt for the best graphics card possible - the built-in graphics on the Mac Mini and Macbook Air are the worst performers. Also, fast disks are very important; Flash storage or SSDs will help tremendously. We recommend at least 16GB of RAM.
Q - So what's the minimum spec?
A - For Mbox v3, the computer must be an Intel Mac, with a Core2 (64-bit) processor, running macOS 10.6.7 Snow Leopard or newer. You'll need at least 4GB of RAM. For Mbox v4 the same minimum hardware is required, but you will need to use at least macOS 10.10 Yosemite. We strongly recommend using at least macOS 10.11.5 El Capitan and having at least 16GB of RAM for Mbox v4. A computer with a discrete (not an integrated Intel GPU) graphics card will provide better results. We also strongly recommend using SSDs or flash storage for boot and a separate SSD/flash drive for content.
Q - What steps should I take in setting up the computer to get Mbox to work better?
A - Generally you want reduce overhead and also disable things that might interfere with Mbox. Run the OS from one hard-drive and put content onto a second, fast drive. Turn off: file sharing, remote management, screen savers, BlueTooth, Time Machine, Spotlight, notifications, software updating, sleep, iCloud, Flash, Java, Expose & Spaces, automatic time & date. Remove everything from login items, eliminate anything that uses processor, GPU, or network time unnecessarily. Disconnect unneeded peripherals: monitors, hard-drives, USB, etc.
Q - Should I upgrade to the latest version of the Operating System?
A - In almost all cases, if Mbox is working properly on your current OS we strongly recommend that you NOT upgrade the OS. In several cases we have found that the newest versions of the OS will break parts of Mbox before we can react and change the software.
Q - Can I use Mbox with macOS 10.10 Yosemite?
A - Yes. But for Mbox v4 we strongly recommend using El Capitan instead. For Mbox v3, make sure you are running the most recent version of Mbox software (v3.10.2). If you're using a USB license key, make sure to update to the correct dongle drivers!
Q - Should I use Mbox with macOS 10.11 El Capitan?
A - At this time it is OK to use Mbox v3.10.1 and v3.10.2 with El Capitan 10.11.x. For Mbox v4 we have found that El Capitan provides significantly better performance than Yosemite. To use the USB license key on a computer running El Cap, make sure to update to the correct dongle drivers! For El Capitan this is "Dongle Drivers OS 10.9 - 10.11"
Q - Can I use Mbox with macOS 10.12 Sierra?
A - We strongly advise against using Mbox v3 with macOS 10.12 Sierra. For Mbox v3, you may find that performance is poor or that some features do not work. For Mbox v4 everything is fine. To use the USB license key on a computer running Sierra, make sure to update to the correct dongle drivers! Currently this is "Dongle Drivers OSX 10.12 - 10.14"
Q - Can I use Mbox with macOS 10.13 High Sierra?
A - We strongly advise against using Mbox v3 with macOS 10.13 High Sierra. For Mbox v3, you may find that performance is poor or that some features do not work. For Mbox v4 everything should is fine aside from some minor UI slowdowns. To use the USB license key on a computer running High Sierra, make sure to update to the correct dongle drivers! Currently this is "Dongle Drivers OSX 10.12 - 10.14"
Q - Can I use Mbox with macOS 10.14 Mojave?
A - Starting with Mbox v4.3.2 (and Mbox Player v1.1), the Mbox application and its companion applications are compatible with Mojave. However, older versions are not compatible and will not run on Mojave. Mbox v3.x apps will never work with Mojave and therefore should not be used with this version of the OS. If you have a license for Mbox v3 you will need to purchase an upgrade to Mbox v4 if you need to run the software on a computer that uses the Mojave OS.
Q - Can I use Mbox with macOS 10.15 Catalina?
A - At present time, Catalina provides no advantage over Mojave and we recommend that you do not upgrade. However, starting with Mbox v4.4.1 (and Mbox Player v1.2.1), the Mbox application and its companion applications are compatible with Catalina. Older versions of software are not fully compatible and may not install correctly on Catalina. Note: The location of the Mbox content folder must move to install Mbox on a computer using Catalina. Mbox v3.x apps will never work with Catalina. If you have a license for Mbox v3 you will need to purchase an upgrade to Mbox v4 if you need to run the software on a computer that uses Catalina.
Q - Can I use an eGPU (external GPU) with Mbox?
A - Starting with macOS 10.14 Mojave, Apple supports the use of external GPU's connected to the Mac computer via Thunderbolt 3. We have done testing, but can't make any promises of improved performance or stability. The eGPU only provides a benefit if the computer has a built-in GPU (Intel), and only if your content is encoded using the Hap codec. If an eGPU works well for you, feel free to let us know what hardware you are using!
Q - What video capture card should I buy to use with Mbox?
A - Mbox has optimized support for Blackmagic Decklink and UltraStudio devices and Active Silicon Phoenix PCIe capture cards. Mbox also works with PCIe capture cards or other devices that use QuickTime streaming. Designer v3 supports up to four inputs, whereas Mini v3 and Studio v3 support up to two inputs. In Mbox v4, Designer can have eight inputs, Studio four, and Mini two. Note that some devices do not support all of the formats listed in the video setup format selection. Check your device documentation and only select formats that your device supports!
Q - What version of Blackmagic Decklink software/firmware should I install on my computer?
A - If using Snow Leopard (OSX 10.6) you should not install Decklink drivers version 10 or higher - you should use version 9.9.2. With newer versions of macOS you can install Decklink Desktop Video 10 or higher, check the Blackmagic website for the appropriate version. Note: We have had reports that some versions work better than others e.g. 10.2 performs better than 10.3. Therefore we don't recommend updating driver versions unless absolutely necessary.
Q - How many video inputs can I have with Mbox?
A - In Mbox v3, Mini and Studio allow two inputs from a capture card, USB, or Thunderbolt device and Designer allows four. In Mbox v4, Mini allows 2 inputs, Studio allows four inputs and Designer allows eight. Note: Using multiple inputs at the same time when receiving HD inputs may affect overall performance depending on the hardware used.
Q - Can I use a Matrox DualHead2Go or TripleHead2Go, or a Datapath X4/FX4 with Mbox?
A - Yes. Though if you're using the rental IO Module hardware you may need to bypass the video in that unit and connect the device directly to the computer. Mbox Remote allows you to set up each physical output of the computer to work with these devices - separate overlap, blend, keystone, and warp. Be aware that on the Mac, the these devices will not allow a 3x 1920x1080 (5760x1080) setup, or anything wider or taller than 4096 pixels.
Q - Why don’t I get any video/picture from out of the Stage DVI connector on my Mbox Extreme Dual IO Module, but I have a picture on the Preview DVI connector?
A - Make sure that Mbox is running and in Fullscreen Mode. Make sure the Camera/Master Fixture’s Intensity parameter is at a level above 0. Check USB indicator lights on IO Module and USB connections between Mac and rear of IO Module. The Stage output is dimmed separately from the Preview output. When Mbox is not running or is in Window Mode, the Stage output is completely blacked out.
Mbox v4 Software Specific
Q - I want to install Mbox v4.4.1 but the installer tells me I have an Mbox folder at the root of my boot drive and the location is no longer allowed. What do I do?
A - To allow compatibility with macOS 10.15 Catalina and beyond, the Mbox content folder (or an alias to that folder) can no longer be placed at the root of the computer's boot drive. The new location is in the Applications folder on the boot drive. You can just move the folder or alias (drag and drop in the Finder) and then run the installer again. However, please be aware that older versions of Mbox aren't aware of this new location so you may not be able to use those older versions with Catalina.
Q - How do I master the pixel mapping output, it doesn't respond when dim the output using the Output Master Intensity?
A - You should set up one or more Pixel Mapping Groups; each can have its own mastering.
Q - Can I control external equipment via Serial-Over-Ethernet using Mbox?
A - Yes. Depending on what you are using as a controller, you can either use Director and patch a serial-over-ethernet fixture, or set up scripts in Mbox that open the correct port (TCP or UDP) and send the message. See the Mbox Director training movie regarding serial-over-ethernet setup and control.
Q - Why does the audio in my movie sound weird when the movie first starts playing?
A - the most likely cause for this is that your movie uses embedded audio that was made with LPCM (uncompressed) encoding. Embedded audio in Mbox should be made using AAC encoding whenever possible. If this is not possible, then the audio should be stripped from the movie file and added as sidecar audio. IMPORTANT!! In a future update, Mbox will automatically make "auto-sidecar" audio files for movies having embedded LPCM audio. You won't have to do anything to make this happen.
Content for Mbox v4
Q - What movie codec should I use with Mbox v4?
A - Mbox v4 has switched over to using AVFoundation rather than QuickTime 7 technology. Therefore the list of available codecs has changed. We still recommend the Apple ProRes codec family. It's a great quality codec as long as your computer and disk system can handle the bitrate of the content, as this tends to be a bit high. Newer computers with four or more CPU cores will provide better results. Other preferred codecs are Hap, Photo-JPEG, and H.264, but H.264 is not recommended. The Hap codec provides native GPU-accelerated decompression and may provide better performance when using a computer with a good GPU but limited CPU. Avoid using any other codecs not mentioned here, as they may not work or performance or quality may suffer.
Q - What kind/format of audio should I be using when I embed audio in a QuickTime movie for Mbox v4 to play?
A - For Mbox v4, the format for embedded audio tracks should be 48KHz, and MUST use AAC encoding. LPCM (uncompressed) audio is not currently supported, but an upcoming update will allow for compatibility with LPCM audio by making "auto-sidecar" audio files./p>
Q - What kind/format of audio should I be using when I use sidecar audio files with Mbox v4?
A - In Mbox v4, the format for sidecar audio can be MP3, WAV, AIFF, M4A, or AAC, using 16/24-bit, 48KHz audio.
Q - Can Mbox v4 play multi-channel audio, files with more than two channels?
A - Beginning with Mbox v4.2, Mbox v4 can play multi-channel audio tracks (using embedded or sidecar audio). With Mbox v4, embedded multi-channel must still use AAC encoding, but sidecar multi-channel files can be WAV, AIF, or AAC, and can use LPCM (uncompressed) encoding. To actually get multi-channel audio to output from the computer you will need to use a multi-channel audio interface.
Q - Can I use content encoded with the H.264 codec?
A - In Mbox v4 you can use H.264. However, the Mbox playback engine is still based around playback of spatially compressed codecs (e.g. ProRes and Hap and therefore some playmodes or features will not work properly with H.264 movies. Therefore we still don't recommend using it.
Q - What about image sequences?
A - Beginning in Mbox v4.1 you can use image sequences. The image sequences can be TIFF or PNG. Take care though, because image sequences can use a large amount of disk space!
Networking & Control
Q - What are my options for controlling Mbox without having to use a moving light console?
A - Mbox Director is the conduit for controlling Mbox without a console. Director is a Graphical User Interface (GUI) application written specifically to control Mbox. In addition to onscreen manipulations and the recall of saved scenes, Director allows for Art-Net/sACN, timecode, MIDI, and OSC inputs to trigger scenes and/or manipulate parameter values.
Q - I'm using an MA Lighting grandMA console and I can't play all of my content folders/files, what's wrong?
A - Check to see if the console is actually outputting the DMX value that you have dialed up on the encoder - use the DMX sheet. Depending on the profile for the console, you may find that some parameters are set to the "generic" range of 0 - 100, rather than the range of 0 - 255. The folder and file organization on Mbox requires the console to be able to output the full range!
Q - Can Mbox input or output MIDI and OSC?
A - Mbox cannot directly receive either of these protocols, but Mbox v4.4 and beyond can output OSC. Mbox Director can receive MIDI and OSC and can also output MIDI feedback and full OSC messages, so these protocols can be used to trigger scenes in Director or manipulate parameter values directly.
Q - Mbox doesn't seem to sync properly to my 29.97 non-drop timecode feed, what's wrong?
A - Timecode that is 29.97fps was originally intended to be drop-frame timecode. The drop-frame helps account for the fact that the signal has a fractional number of frames per second. Mbox was designed to automatically work with 30fps non-drop and 29.97 drop-frame time code. But since 29.97 non-drop is quite prevalent, Mbox can compensate for this. There is a pref (TC 29.97ndf compensation) that can be enabled on the Preferences tab in Mbox or using Mbox Remote.
Q - Any time Daemon runs with two or more Ethernet connections linked I receive the error "MboxDaemon: Network IP Address Conflict: - - "
A - This happens when the Ethernet connections listed in the dialog are on the same network Subnet. In order to correct this issue the network settings in System Preferences > Network must be modified such that each interface is on it's own network subnet. for example if has an IP of 2.x.x.x with a subnet of 255.0.0.0 then the first octet of must not be a 2. Visit http://en.wikipedia.org/wiki/Subnetwork#IPv4_subnetting for more information.
Q - Why doesn’t my console profile control Mbox correctly, can you fix it please? Can you make me a profile for XYZ console?
A - Unless it’s a profile that we created (the official PRG Vx76 or grandMA profiles) no, we cannot fix your profile, sorry. Also, we cannot create profiles for any consoles other than the PRG Vx76 console line and the MA Lighting grandMA line. Problems with profiles that are made by the console manufacturer need to be fixed by them. We are happy to work with you and them to make the necessary corrections and test them. But more often than not, the request for a corrected profile receives more attention when it comes from the console user, not from us.
Q - What sort of Ethernet switch should I use with Mbox?
A - Ideally you should run Art-Net into Mbox on one physical Ethernet port on the computer and other network protocols (monitoring, content management, etc.) on a second port. Because Art-Net is a 10 Mbit/sec protocol just about any switch will work for that. For the other protocols we recommend a gigabit switch with some advanced management features. The switch should be non-blocking, Multicast aware, and must have Broadcast Storm Control disabled. Two great choices would be the Pathway VIA and Luminex GigaCore switches.
Q - Can I control Mbox with Mbox Director and a console at the same time?
A - Yes you can. Mbox Director 3.8 introduced a “pass through” function to allow the app to receive and pass through certain data while replacing other data. The Director interface allows you to select which parameters are passed through or replaced. Note: This is not literal merge of Art-Net data though, as the universe number on the input and output must be different.
Q - I’m using one computer to run both Mbox and Director, how should I set up the screens?
A - To properly run both Mbox and Director on the same computer, you must run Director on the primary monitor of the computer. Mbox v3 (in single output mode) will happily run in fullscreen mode on the second output of the computer. To get this to happen, go to the Setup tab and select “Output 2” on the popup in the Single Output Setup area. Then go into fullscreen. Mbox v4 can go into fullscreen mode on any output of the computer.
Q - Is there a way in Mbox to control other devices like projectors, shutters, and so on?
A - In Mbox 3.x and 4.0 - 4.3.x, you can trigger both AppleScripts and Shell scripts from within Mbox. Depending on the connected device, one or both of the scripting methods can be used for most devices that support a telnet connection. Including ImagePro, Barco projectors, PJ-Link projectors. Mbox 4.4 introduced the ability to directly output OSC commands. Note that Mbox Director also has OSC functionality.
Q - Does Mbox do CITP(MSEX)?
A - Yes, Mbox supports the CITP (MSEX 1.0 & 1.1) protocol for output of both content thumbnails and streaming. Mbox outputs a stream for each output and layer. CITP has been tested with PRG Vx76, MA Lighting MA2 consoles and MA3D visualizer, HES Hog4, CAST WYSIWYG, Capture Polar, ChamSys MagicQ. Please note that due to the complexity of CITP, not all features may be available "out of the box" with some products that support CITP. We often have to work with the product developers to ensure full compatibility.
Q - How do I set the output resolution for Mbox Player's output?
A - Mbox Player will always use the current resolution and frequency of the computer's second video output. This means that you have to configure the output resolution and frequency in the System Preferences > Displays pref pane..
Q - Why does Mbox Player show a show file error when I launch the application or try to open my show file ?
A - Either your show file has been corrupted, or you are attempting to open a show file made with a newer version of Mbox Player. Mbox Player v1.3 show files are not compatible with older versions of Player.
Q - Why does the audio in my movie sound weird when the movie first starts playing?
A - the most likely cause for this is that your movie uses embedded audio that was made with LPCM (uncompressed) encoding. Embedded audio in Mbox Player should be made using AAC encoding whenever possible. If this is not possible, then the audio should be stripped from the movie file and added as sidecar audio to the movie clip. IMPORTANT!! Starting with Mbox Player v1.3, Player automatically makes "auto-sidecar" audio files for movies having embedded LPCM audio. You don't have to do anything to make this happen.
Mbox Software General (v3 & v4)
Q - How can I see movie playback information (file name, codec, total time, remaining time, etc.) on my computer when I’m using Mbox?
A - You can see much of this information if you’re controlling Mbox with Director, but if you are using a console or want someone else to see this information, Mbox Remote can show you this. On the Status tab in Remote you can select the Custom view mode and then drag individual servers onto the blank area, and then drag layers from those servers into blank area to see more detail about movie playback on each layer.
Q - If I’m running an Mbox as a ‘hot backup’ of another Mbox, how do I avoid outputting Layer Sync and Pixel Mapping data from the backup machine?
A - Turn on the Backup Mode switch on the backup Mbox. You can do this using the Mbox Remote application or by sending the server’s Master Control parameter to a value of 234, holding that for three seconds and then returning the parameter directly to zero.
Q - I want to get Mbox to respond to audio so I can change the video onscreen to match the volume/rate/frequency of the audio. How do I do this?
A - Mbox does not currently accept audio inputs for effects generation. The best method to achieve this result is to create a Quartz composition that reacts the way you want and then use Syphon to get that composition’s video into Mbox.
Q - What's with the lighting built into Mbox?
A - Mbox has always had some form of virtual lighting for the illumination of 3D objects within its rendered 3D environment. Without lighting, 3D objects are not visible. Software versions prior to 3.8 had five lighting fixtures total, and depending on which product you were using they were fixed color and intensity (Studio) or adjustable color and intensity (Designer). You could not move the lighting fixtures; they were fixed in a standard McCandless arrangement. Mbox 3.8 to 3.10 added the concept of "Pro Lighting" fixtures to Mbox Designer. Pro Lighting fixtures are optional fixtures that override/cancel the results of all five of the standard lighting fixtures. They not only have a movable position, but are also adjustable from spot to ambient. Beginning with Mbox v4.0, Designer and Studio both have five lighting fixtures, and these fixtures match the capabilities of the Pro Lighting fixtures in Mbox v3.
Q - What is Syphon and what can it do for me?
A - Syphon is an open source technology that allows multiple applications on the same computer to share video, both input and output. Mbox can receive video from other Syphon-aware applications like Quartz Composer, Resolume, and Modul8. And Mbox can also output its video to those same applications and others. Syphon can be use to extend the capabilities of the Mbox application to make use of the capabilities of other apps as well.
Q - What do I do if I want to program Mbox on my own computer using one version of the app, and then run it on another computer using a different version of the app?
A - New releases of Mbox software will work to run a show programmed using the previous version of software; you can select the older mode on the setup tab (v3) or on the Patch tab (v4). However, to take advantage of new features you will have to use the newest mode. Note that in some cases Mbox v4 cannot replicate features in Mbox v3 due to the significant changes in how the application works - e.g. output control, alignment rectangles. In Mbox v3 you can also program a show using Mini or Studio and run that show using a higher version: Mini can only run a Mini show, Studio can run Mini and Studio, Designer can run all three. In Mbox v4 all three versions can emulate the others. However, due to the limitations in Studio and Mini, they won't be able to use parameters that fall outside those limits (e.g. the number of effects per layer).
Q - What is Image Remapping (AKA the multiscreen gobo) and how do I use it?
A - Image Remapping is a feature that allows specific pixels from content played on a layer to be repositioned elsewhere on the output. It can be useful for positioning content in specific areas of the output screen for LED systems or for 2D scenic tracking. Check out the training movies on Image Remapping for more info.
Q - Can I use Mbox for Pixel Mapping to DMX/Art-Net lighting fixtures?
A - Yes. All versions of Mbox allow for the output of Art-Net, sACN, and Color Kinetics KiNET (v1 & v2) - at the same time if desired. Currently Mbox v4 can control RGB, RGBW, RGBAmber, Intensity, CMY, CYM, and HSV fixtures. The setup allows for different screen sub-sampling for different fixture types as well as broadcast, unicast, and automatic (ArtPoll) data destinations. Mbox 3.9 included a complete overhaul of the pixel mapping toolset, which was further enhanced to add internal merging in Mbox 3.10 and selectable sources for pixel mapping in Mbox v4.
Q - If I'm playing content with audio, can I control the volume of the audio?
A - All versions of Mbox have a master audio volume parameter on the Global Master (v4) or Master/Camera (v3) fixture. In Mbox v3, Studio and Designer allow you to have per-layer volume control with either the opacity parameter controlling both opacity and layer volume or added channels patched to a specific control universe and address. In Mbox v4, all versions have a permanently assigned layer volume parameter for every layer plus a master volume control on the Global Master.
Mbox v3 Software Specific
Q - My Fullscreen output resolution/frequency is not matching what I had set in the Fullscreen mode settings on the Mbox Setup Tab.
A - In order for Mbox (or the host Mac) to display any specific fullscreen mode the connected display or device (such as an ImagePRO®) must present the the correct EDID (Extended display identification data) in order for the Mbox to display the configured resolution and frequency. the EDID is transferred over the connected display cable and informs the Mac, and thus Mbox, of the capabilities of the device. If the requested resolution and/or frequency is not available in the EDID table then Mbox will choose the closest match. You can confirm the current FullScreen mode by pressing (fn) + F9 while in Full Screen Mode and reading the resolution and frequency in the displayed HUD. Additionally, versions of Mbox from 3.7 to 3.10 provide a "For Current Display" mode that uses the desktop mode for Mbox’s FullScreen Mode and is described in the Mbox manual under Setup : FullScreen Mode.
Q - My content is playing back at a size smaller than expected within Mbox and when scaled back up to normal size it looks pixelated.
A - Any time content is played back within Mbox it must be the same size or smaller than the width and height entered in the Mbox Setup Tab > Texture Size fields. If your content is larger in either dimension then Mbox will repeatedly half the size of the content until it fits within the texture size. Either correct the size of the content or increase the texture size as needed. Note that the texture is one of the largest contributors to the performance of Mbox and should be kept as small as possible. Additionally if the Texture size value is changed then Mbox must be restarted.
Q - Is it possible to assign a layer to more than one Alignment Rectangle?
A - Although each layer may have more than one effect that can be assigned to the Auto Crop Effect only the highest numbered Effect assigned the autocrop effect will be used. Topo objects (Studio/Designer) and Image Remapping (Mini/Studio/Designer) are better for remapping content to one or more region of the screen.
Q - So what is "Pro Lighting" in Mbox Designer 3.8?
A - Pro Lighting fixtures are optional fixtures and do not have to be added or patched to use Designer. If you do patch even one of them, they will override/cancel the results of all five of the standard lighting fixtures. They not only have a movable position, but are also adjustable from spot to ambient.
Q - How do I keystone the two outputs separately when using Mbox in Panoramic Wide mode?
A - Use the projection mapping keystone/warp tools built into the Mbox Remote application.
Content for Mbox v3
Q - What movie codec should I use with Mbox v3?
A - We recommend the Apple ProRes codec family. It's a great quality codec as long as your computer and disk system can handle the bitrate of the content, as this tends to be a bit high. Newer computers with four or more CPU cores will provide better results. Other preferred codecs are Photo-JPEG, Apple Intermediate, Animation, and Motion JPEG-A. You should avoid using other codecs as performance or quality may suffer.
Q - What kind/format of audio should I be using when I embed audio in a QuickTime movie for Mbox v3 to play?
A - While the format doesn’t really matter in this case (as long as the QuickTime app on the same computer can play the audio properly) 44.1KHz, 16-bit encoding is more than adequate. 48KHz, 24-bit will also work with no issue but is probably of higher quality than necessary.
Q - Can Mbox v3 play multi-channel audio, stuff with more than two channels?
A - Yes, if the audio is embedded in a QuickTime movie. To actually get all the audio to output from the Mac you will need to use a USB or FireWire audio interface. Audio tracks should be assigned to the "discrete" channels in QuickTime in order to work properly.
Q - Can I use content encoded with the H264 codec?
A - The rule of thumb with Mbox v3 is Don’t Use the H264 Codec!! Please, for your benefit, use some other codec. H264 is popular and has a low bitrate. But it isn’t well implemented in QuickTime 7 which means that H264 can cause issues in Mbox. We have seen H264 lead to crashing of the Mbox application. Despite the higher bitrate, codecs like Photo-JPEG, AIC, and Apple ProRes are much preferred.
