INTRODUCTION

QTAKE is the most advanced software application designed and developed for video assist

professionals. It is used to log, capture, playback, edit and process video output of the 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

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

provides entirely silent operation.

HOW IT WORKS

QOD+ converts DisplayPort output of your Mac to four independent SDI outputs supporting all

standard HD-SDI and 3G-SDI frame rates. When QOD+ is connected 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).

March 08, 2023 TABLE OF CONTENTS 2

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 need to

use DIP switches to control the QOD+ unit.

Please refer to STANDALONE OPERATION for more details.

Also, add the following preference in the Qtake_Prefs.txt ﬁle located in the QTAKE Prefs folder on

your Mac:

QOD_Mode=1

QOD+ INSTALLATION

GENERAL INSTALLATION

QOD+ Installation requires 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 busses on the back. To avoid the QOD+ showing up

as your primary monitor it should be connected 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 input signal and

Green indicates that signal is acquired. When the device is in standalone mode, the LED will light

yellow-green.

FIRMWARE UPDATE

QOD+ contains programmable chip that can be upgraded by user to apply bug ﬁxes or additional

functionality. Firmware update is performed using QTAKE, which 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).

DISPLAY MENU

If you need to change the input resolution of the QOD+ without QTAKE, use an application called

DISPLAY MENU. Display Menu can be downloaded 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 output from the QOD+, 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 standalone operation, please refer to the STANDALONE OPERATION

chapter of this user guide.

QTAKE GPU output always run at 50Hz or 60Hz frequency. This means that 24fps video playback

repeats original frames in 3-2-3-2 cadence in order to ﬁll out 60Hz DisplayPort output. This is

called (3:2) pulldown. During signal conversion from DisplayPort to SDI, QOD+ will identify original

frames and discard repeated ones. This pulldown removal is essential mechanism in order to

produce smooth 24fps or 25fps SDI output. However, there is additional frame of latency, because

it requires buﬀering - waiting to receive next frame. In order to output SDI signal with the lowest

possible latency, user needs to 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 USB connection. Settings can be changed in the QOD

toolbar in the FILE room. The QOD toolbar displays the following information:

SERIAL NUMBER

Serial number of the QOD+.

March 08, 2023 TABLE OF CONTENTS 8

QOD RESOLUTION

Current input resolution of the QOD+.

TEMP

Internal temperature of the QOD+. QTAKE will notify the user with a message in the status bar if the

temperature of the QOD+ exceeds 76 C. The QOD+ will shut down if the internal temperature

reaches 85 C to prevent damage to internal components.

QOD AUDIO

This button controls the audio input and embedded audio output of the QOD+. Your options are:

NONE - No audio is embedded on the output.

AUDIO IN - The analog line audio input is embedded on all SDI outputs.

DISPLAYPORT2/8 - Each SDI output uses 2 of the 8 audio channels available from the DisplayPort

input. This allows each view to have independent embedded audio, but limited to stereo.

DISPLAYPORT 8/8 - All 4 SDI outputs use all of the 8 audio channels available from the DisplayPort

input.

FIRMWARE

Use this button to update ﬁrmware of the QOD+. After updating ﬁrmware, you need to quit QTAKE

and power-cycle QOD+. After QOD+ is detected by the operating system, you can start QTAKE

application.

RESET

Performs a soft reset of the connected QOD+.

GPU OUT SETTINGS

QOD+ output channels are controlled using the GPU OUT window. QOD FORMAT can be set to

either 1080p, 1080i or 1080psf. QOD FPS can be set from 23.98 to 60 or AUTO. Setting QOD+ FPS

to AUTO means that QOD+ will output signal at the same frequency as the clip in the

corresponding view. The QOD AUDIO setting is the same as in the QOD toolbar and applies to all

outputs.
