QOD+ USER GUIDE
QTAKE is the most advanced software application designed and developed for video assist professionals. It logs, captures, playbacks, edits, and processes video output of Digital Cinema Cameras as well as traditional film cameras with a video tap.
The QTAKE Output Device - QOD+ is the ultimate hardware device developed by IN2CORE to provide a superior solution for GPU-driven low-latency video output. It supports up to four independent 3G SDI outputs or a single UHD output. QOD+ is a fanless version of the previous QOD model, thus providing entirely silent operation.
HOW IT WORKS
QOD+ converts the DisplayPort output of your Mac to four independent SDI outputs supporting all standard HD-SDI and 3G-SDI frame rates. When you connect QOD+ to your Mac, it is detected as an external monitor.
The QOD+ can operate in two modes:
- STANDALONE, where settings are adjusted by the DIP switches on the side of the device,
- USB CONNECTED, where the QOD+ is controlled by QTAKE via USB connection (only QTAKE version 1.2 or later supports “connected” mode).
The following are minimum hardware and software system requirements:
- Apple Mac computer with DisplayPort or Thunderbolt output running OS X 10.10.5 or later,
- QTAKE version 1.2 or later
QTAKE GUI DESCRIPTION IN THIS USER GUIDE DOES NOT APPLY TO OLDER VERSIONS OF QTAKE!
If you are running QOD+ with an older version of QTAKE (version number below 1.2), you have to use DIP switches to control the QOD+ unit.
Please refer to STANDALONE OPERATION for more details.

QOD HDR OUTPUT
Starting with QTAKE Pro v2.1, QOD supports High Dynamic Range output. SDI Monitors with HDR payload detection will correctly set the colorspace and other HDR metadata when connected to QOD.
QOD+ package includes:
- QTAKE Output Device (QOD+)
- Power supply
- MiniDisplayPort-to-DisplayPort cable
- MiniUSB-to-USB cable
QOD+ Installation requires a few simple steps:
- Connect the DisplayPort cable to the DP IN port on the QOD+ and connect the other end (mini DisplayPort) to a DisplayPort/Thunderbolt port on your Mac.
- Connect the USB cable to the port labeled USB on the QOD+ and the other end to an available USB port on your Mac.
- Connect the Power supply to the QOD+.
- Start up the Mac.
New Mac Pro computers have three Thunderbolt buses on the back. To avoid the QOD+ showing up as your primary monitor, connect it to Thunderbolt bus 0 (bottom two Thunderbolt connectors) and your GUI screen to bus 1 or 2. That also means you should not connect your primary monitor (GUI) to the HDMI output of your Mac Pro. See this Apple knowledge base article for more details.
The RGB LED next to the power jack indicates the operational state of the QOD+. When the device is booting, the LED will flash white. Red indicates that the QOD+ is waiting for the input signal, and Green indicates that the signal is acquired. When the device is in standalone mode, the LED will light yellow-green.
The QOD+ contains a programmable chip that you can upgrade to apply bug fixes or additional functionality. Use QTAKE to perform firmware updates. It is bundled with the latest firmware binary. Do not attempt to downgrade the QOD+ by updating the firmware from an older version of QTAKE.
When the QOD+ is plugged into the DisplayPort/Thunderbolt port of your Mac, the operating system will detect it as a new monitor. You can verify that macOS has detected your QOD+ in System Preferences - Displays or use the Display Menu application (see DISPLAY MENU below).
When handling with QOD+, ensure to power off the device by disconnecting the power cord. This step is vital to prevent internal shortages when connecting or disconnecting SDI output cables.
If you need to change the input resolution of the QOD+ without QTAKE, use the Display Menu application.
You can download the Display Menu app from the App Store for free.
QOD+ supports following resolutions:
1920 x 1080 - Single HD output, all SDI outputs will output the same image
3840 x 1080 - Dual HD output, SDI output 3 and 4 will mirror outputs 1 and 2.
1920 x 3240 - Triple HD output, SDI output 4 will mirror output 1.
3840 x 2160 - Quad HD output, each SDI output is independent.
To ensure smooth QOD+ output, the device removes duplicated frames from the DisplayPort input signal. This results in an output format that perfectly matches the source. QTAKE enables this feature automatically upon startup if there is a USB connection to the QOD+. To enable pulldown removal in a standalone operation, please refer to the STANDALONE OPERATION chapter.
QTAKE GPU output always runs at 50Hz or 60Hz frequency. It means that 24fps video playback repeats the original frames in a 3-2-3-2 cadence to fill out 60Hz DisplayPort output. It’s called (3:2) pulldown. During the signal conversion from DisplayPort to SDI, QOD+ identifies original frames and discards repeated ones. This pulldown removal is an essential mechanism to produce smooth 24fps or 25fps SDI output. However, there is an additional frame of latency because it requires buffering - waiting to receive the next frame. To output an SDI signal with the lowest possible latency, set QOD+ to output 1080p60 or 1080i30 video mode (or 1080p50/i25 in case of 50Hz GPU output). This output mode will turn off buffering because it doesn’t perform pulldown removal.
QTAKE USB CONTROL
QTAKE controls the QOD+ operation via a USB connection.
You can change settings in the
QOD toolbar in the FILE room.
The QOD toolbar displays the following information:
Serial number of the QOD+.
QOD+ Current input resolution.
QOD+ internal temperature. QTAKE will notify you with a message in the status bar if the QOD+ temperature exceeds 76 Celsius. The QOD+ will shut down if the internal temperature reaches 85 Celsius to prevent internal components damage.
This button controls the QOD+ audio input and embedded audio output. Your options are:
None - No embedded audio in the output.
Audio In - Embedded analog line audio input in all SDI outputs.
DisplayPort2/8 - Each SDI output uses 2 out of 8 audio channels available from the DisplayPort input. It allows each view to have independent embedded audio but is limited to stereo.
DisplayPort 8/8 - All four SDI outputs utilize all eight available audio channels from the DisplayPort input.
Use this button to update the QOD+ firmware. After updating the firmware, you need to quit QTAKE and power-cycle QOD+. Once the macOS detects the QOD+, you can start the QTAKE application.
This button performs QOD+ soft reset.
GPU OUT SETTINGS
The GPU OUT window controls QOD+ output channels.
QOD FORMAT can be set to either 1080p, 1080i or 1080psf.
QOD FPS can be set from 23.98 to 60, Clip or Input.
Setting QOD+ FPS to Clip means that QOD+ will output a signal at the same frequency as the clip in the corresponding VIEW.
Setting QOD+ FPS to Input means that QOD+ will output a signal at the same frequency as the LIVE input in the corresponding VIEW.
The QOD AUDIO setting is the same as in the
QOD toolbar and applies to all outputs.
Since QOD+ has four 3G SDI connectors, you achieve 4K output by using all four output connectors. QTAKE sends one quadrant of 4K resolution into each QOD+ SDI OUT connector. Therefore your monitor has to support quad link SDI to display the 4K QOD output. Alternatively, you can use a 4x3G -> 12G SDI or 4x3G -> HDMI converter to get QOD 4K output into your monitoring device.
QOD+ DIP SWITCH CONTROL
When using QOD+ with another software or no USB connection is available, you can set the QOD+ operational modes via DIP switches. Refer to the image below to set the requested modes. More details are available in the STANDALONE OPERATION section.
You can use 12 DIP switches on the side of the QOD+ to set the QOD+ into standalone operation mode. When you set the QOD+ into standalone mode, it will ignore commands and communication sent through the USB interface. The DIP switches control the following options: (1 = on, 0 = off).
|Ignores DIP switches
|RGB Legal Range
|RGB Full Range
|Drop frame mode
|Non-drop frame mode
|Depends on Frame Mode
|Depends on Frame Mode
|Depends on Frame Mode
|DisplayPort audio 8/2
|Analog audio Input
|DisplayPort audio 8/8
|No pulldown removal
|Flag pulldown removal
|Test pattern output
These QTAKE preferences are relevant to the operation of QOD+. Use the PREFERENCES button in the INFO menu to open the window with preferences and set the required options.
Alternatively, you can use the Text Edit application to edit the content of the preference file. QTAKE preferences file resides in the [System volume]/Users/[User name]/Library/Application Support/com.in2core.QtakePro/Prefs folder. If you delete this file, QTAKE will recreate one with the default settings. Changes will take effect next time QTAKE starts.

- Quit QTAKE
- Turn off QOD+
- Turn DIP Switch 1 to position ON, all other DIP Switches to position OFF
- Turn on QOD+
- Turn all DIP Switches to position OFF
- Start QTAKE
