INTRODUCTION
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).
SYSTEM REQUIREMENTS
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+ INSTALLATION
GENERAL INSTALLATION
QOD+ Installation requires a few simple steps:
1. 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.
2. Connect the USB cable to the port labeled USB on the QOD+ and the other end to an
available USB port on your Mac.
3. Connect the Power supply to the QOD+.
4. Start up the Mac.
MAC PRO
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.
QOD+ STATUS
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.
FIRMWARE UPDATE
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.

OPERATION
GENERAL OPERATION
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).
WARNING
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.
DISPLAY MENU
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.
PULLDOWN REMOVAL
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:
August 22, 2023 7
SERIAL NUMBER
Serial number of the QOD+.
QOD RESOLUTION
QOD+ Current input resolution.
TEMP
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.
QOD AUDIO
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.
FIRMWARE
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.
RESET
This button performs QOD+ soft reset.
August 22, 2023 8
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.
