1 Overvie
This manual describes the usage of the ProVideo GUI by Dream Chip. The GUI is used to
setup supported ProVideo devices which are attached over a serial interface. The GUI is
currently available for inux and Windows operating systems and supports the following
devices:
•ATOM one
•ATOM one mini (including AIR and waterproof variants)
•ATOM one 4K Mini
•ATOM one SSM500 (Trigger and SSM Mode)
The goal of this document is to describe the full functionality of the GUI. Not all devices
listed above support all features, so the actual appearance of the GUI might vary.
The screenshots in this documentation were created, while the GUI was connected to an
ATOM one camera. The application was run on a desktop PC running Ubuntu 18.04, on
other operating systems the style of the UI elements may vary.
The GUI mainly consists of two windows: The connection dialog is used to establish a
connection to a device, while the main window is used to setup the device. They are
described in detail in the following chapters.
The GUI is open source software, you can get the source code from Git ab:
https://gitlab.com/dreamchip/provideo-gui
The latest firmware and software updates, manuals and application notes for Dream Chip
products, including updates for the ProVideo GUI can be downloaded here:

2 Connecting ith a Device
The GUI supports serial connections using either the RS485 or RS232 protocol. When
using RS232 only one device can be connected at a time, with RS485 multiple devices
can be connected over one bus. The standard power cable adapter provided with most
devices uses RS485.
On application startup the GUI will automatically search for connected devices on the last
used COM-Port. If one ore more devices are found, the GUI will connect to the first device
and directly open the main window. If no device can be found the connect dialog will open.
It has two pages, one for setting up RS485 the other for RS232 connections:
1 Choose between RS485 or RS232 connection.
2 COM-Port to which the device is connected. This will be “ttyUSBX” on inux and
“ComX” on Windows.
3 The Baudrate has to match the Baudrate of all connected devices. Using devices
with different Baudrates on the same RS485 Bus is not supported.
4 The Auto-Detection will find all devices wich are connected to the selected COM-
Port and match the selected Baudrate.
5 If the Auto-Detection fails, you can try the automated scan which will find all
devices which are connected to the selected COM-Port.
6 When manually connecting to a device, the Device Address has to match the
device parameters.

7 When connecting a new COM-Port device after the GUI was launched, click this
button to add it to the Port list.
8 Close the Connect Dialog. If you have previously tried to establish a connection to
a device, but the connection was unsuccessful, this will close the GUI (since it is in
disconnected state).
9 Connect to the device which is specified through the above mentioned settings
(see points 2, 3 and 6).

3 General navigation
After the connection was established, the main window will open. It has toolbar for general
options and a sidebar to navigate through the sub pages of the GUI.
3.1 Toolbar
1 Open the connect dialog (see chapter 2).
2 Open the system settings dialog ( see chapter 3.3)
3 oad settings from camera to GUI.
4 Save settings from GUI to camera for startup configuration.
5 Switch to configuration of SDI 1 UT.
6 Switch to configuration of SDI 2 UT.
7 Save current system settings to disk.
8 oad settings from disk into GUI and transfer them to the device.
9 Switch between connected devices. Only visible if the auto-detection was used to
connect with the device over RS485. The first number represents the device
address, the second number the device broadcast address.
10 Toggle broadcast mode. In broadcast mode the currently selected device will be
the broadcast master, all other devices in the same broadcast group will be slaves.
Settings applied to the master will also be applied on all slaves.
11 The Synchronise button is only enabled, if broadcast mode is active. Click it to
apply the settings of the current device (broadcast master) on all other devices
(broadcast slaves).
Note regarding ATOM one SSM500 cameras in Trigger Mode:
The ATOM one SSM500 in Trigger Mode has two independent chains ( ive and Playback).
The “SDI-1” and “SDI-2” buttons will thus be shown as “ IVE” and “P AY” and can be used
to switch to setup of either chain.
Additionally a new button “ IVE → P AY” will be shown if an ATOM one SSM500 in
Trigger Mode is detected. This button can be used to copy all settings from the ive chain
to the Playback chain. If you want to always apply all settings for both chains, enable the
“ ink” button which is placed to the right of the “ IVE → P AY” button.

3 Change the Calibration Profile. The amount of profiles available depends on the
camera model, this setting is not available on all cameras. For details see the
description of the “calibration_profile” command in the Reference Manual of your
camera.
4 Change the baudrate of the RS232 port of the device. Usually this should be left at
the default setting.
5 Change the baudrate of the RS485 port of the device. Usually this should be left at
the default setting.
6 Change the RS485 address of the device. Before connecting multiple devices to
one RS485 bus, make sure that all devices have different addresses, or you will
have address conflicts!
7 Change the RS485 broadcast address of the device. This is useful if you want to
have multiple broadcast groups on one RS485 bus.
8 Enable or disable the RS485 termination.
Note: RS485 termination has to be setup according to your bus topology. Wrong
termination will degrade signal quality and can cause broken device
communication.
9 Click this button to apply the new Serial interface settings. Without this step, the
settings will be left unchanged.
10 Use this to reset all settings to factory defaults. Careful: This will delete any
calibration you have done, e.g. to the multi color controller. If needed save those
settings separately before performing a full reset!
11 Enable the engineering mode to display additional GUI elements. Careful:
Changing engineering settings can drastically decrease the image quality.
12 Enable the Debug Terminal (see chapter 3.4 for more details).
13 Enable a periodic connection check. If enabled the GUI will ping the connected
device every 2 seconds. If device connection is lost, a dialog will be displayed.
14 Close the settings dialog. Please not that this will not save any settings. If you
have made changes which you want to apply permanently, click the “Apply and
Save” button first.
15 Apply all Settings and Save the settings permanently. This has the same effect as
clicking the save settings button in the toolbar. If you do not want to save the
settings permanently, use the Buttons 2 and 7 and then close the dialog using the
button 11.

3.4 Debug Terminal
The Debug Terminal shows all commands which are send by the GUI. It can also be used
to manually send commands to the device.
By default the Debug Terminal opens as a docked widget of the main window. You can turn
it into a stand-alone window by grabbing it and dragging it away from the main window.
The Debug Terminal can be useful to understand how the ProVideo command system of
your device works. Simply open the debug terminal, make changes in the GUI and watch
the output.
1 History of send / received commands. This window shows a maximum of 10000
lines, older lines get deleted as soon as this limit is reached.
2 The command line can be used to enter your own commands (see the reference
manual of your device for a full list of the available commands). The command line
features a command history which you can access by pressing the Arrow Up and
Down keys on your keyboard while the command line is active. The command
history can contain up to 100 commands, older commands are deleted as soon as
this limit is reached.
You can also copy and paste a list of commands, e.g. from a text document to the
command line, all commands will then be executed. Please make sure that you
have selected an appropriate command response wait time (see point 3).
3 Since the Debug Terminal does not know how long a manually entered command
has to be processed in the device a maximum wait time has to be specified. For
most commands the default of 200ms is sufficient.
For long commands like storing the DPCC table or enabling Genlock you will have
to increase the wait time, otherwise you will not see the answer of the device. If
you run a script with multiple commands by pasting it into the command line make
sure to select a wait time which is long enough for the most time consuming
command in the script.

5 Click this button to save the current content of the Debug Terminal to a text file. If
you experience problems with your device like commands which are not correctly
executed, it can be helpful for the Dream Chip support team if you send them the
command log for investigation.
6 This button clears the content of the Debug Terminal. The command history is not
deleted.

1 Setup the bayer pattern of the sensor. This setting is only visible if “Engineering
Mode” is enabled on the info tab and usually should not be changed by the user.
2 Manually set the shutter time in microseconds. Can only be adjusted if auto
exposure is disabled. Use the Combo Box and the “+” and “-” buttons to the right
of the slider to switch between common exposure time presets.
3 Manually set the sensor gain (ISO). High values will lead to a brighter image bat
also more noise. Can only be adjusted if auto exposure is disabled. Use the
Combo Box and the “+” and “-” buttons to the right of the slider to switch between
common ISO presets.
4 Enable auto exposure. This will automatically adjust shutter time, ISO and aperture
(if available). Turn off to use manual settings (see points 2 and 3). If turned on the
elements 5 to 10 will be enabled.
5 By default the device uses an optimized auto exposure algorithm, which also
works with back light conditions. If you want to manually setup the weighting of the
auto exposure, check this box and click the “Configure AEC Weights” button (see
point 6).
6 This button is only enabled, if the “Use Custom Weights” check box is checked
(see point 5). Click this button to open a dialog to setup the weights of the 5x5
measuring fields of the auto exposure control.
By default all fields are weighted equally with ‘1’, setting a higher value for one of
the fields prioritizes it, that means the AEC will try to correctly expose that field.
The minimum weight is 1, the maximum is 25.
7 The luminance set point defines how bright the auto exposure will set the output
image.
8 The maximum ISO setting defines how high the auto exposure is allowed to adjust
the sensor gain (see point 3). Use a lower value if you want to avoid noise in low
light scenarios, choose a higher value if more gain is needed and noise is of
secondary importance.
9 The control speed defines how fast the auto exposure reacts to changes in the
light conditions. A lower value means a faster reaction, but setting the value too
low might cause the controller to overshoot.
10 Set the anti flicker period to the power frequency of your country (e.g. 50 Hz in
Europe, 60 Hz in North America) to avoid screen flickering when the auto exposure
is enabled.
11 Enable lens shading correction. Please see the notes below this table for detailed
instructions on how to setup the lens shading correction module.
12 The Cosine4 Compensation mainly adjusts the correction in the middle regions of
the image.
13 The Offset determines where the compensation of the outer image regions starts.
14 The slope defines how strong the compensation in the outer image regions is.
15 Set the video mode (resolution and timing).

13 of 36 User Manual - ProVideo GUI v1.2.4
16 Enable 4K to 2K downscaler and optional interlacer for the first SDI output. This
option is only available for 4K cameras, see the cameras reference manual for
more details.
17 Set the mode of the second SDI output. In mirror mode the image is identical to
the first output, in RAW-10 and RAW-12 modes a custom raw image will be output.
Set it to “SDI-2 UT” to use a custom de-gamma UT for the second output. To
configure the UT of the second output additionally you have to switch to SDI-2
config in the Toolbar (see chapter 3.1, point 5 and 6 and chapter 4.9 for more
details).
18 Enable 4K to 2K downscaler and optional interlacer for the second SDI output.
This option is only available for 4K cameras, see the cameras reference manual
for more details.
19 Set the flip mode to mirror the image vertically, horizontally or both (rotate 180°).
20 Enable or disable Audio and setup the audio gain. When enabled the audio signal
of the device internal microphone is embedded into the SDI output signal.
You can change the audio gain via the spin box to the right of the enable button.
The default gain is 1.0, to for example double the volume set a value of 2.0, to half
it set a value of 0.5.
21 Enable HDR / OG mode. In OG mode the gamma curve of all outputs is fixed to
either H G, PQ or S- og3. This generates a “flat” output image which preserves
more details in the highlights.
•In H G OG mode the gain range is adjusted (minimum ISO is doubled) to
match the OG curve.
•In PQ OG mode you can use the “PQ Display brightness” setting to adjust
the gamma curve to your display (see point 22).
•In S- og3 OG mode you can use the “S- og3 Master Gain” setting to
adjust the gamma curve to your needs (see point 22). In this mode the SDI
output range is fixed to “Extended Range”, it can not be changed in the
Output Tab (see chapter 4.12).
Please note that in either OG mode the ookup Table Tab (see chapter 4.9) is
deactivated.
22 Depending on the OG mode (see point 21) you can either setup the PQ display
brightness, or the S- og 3 master gain:
•Setup the PQ display brightness from 100 to 10000 cd/m2. At 10000 cd/m2
the image contains all highlights, but most display will not be able to display
them since they do not achieve the required brightness. At the default value
of 1000 cd/m2 most HDR displays should be able to display the image
without clipping. Only visible if OG mode is set to PQ (see point 21 above).
•Setup the S- og3 master gain from -6 to +12 dB. This feature works
similarly to the “Master Gain” setting of Sony Broadcast cameras. At a
master gain of 10 dB you will use the full SDI code range.
23 Switch between Rec.709 and Rec.2020 color space. This will also change the
color conversion matrix (see chapter 4.12)
24 Enable genlock in slave mode (when connecting an external sync source) or

14 of 36 User Manual - ProVideo GUI v1.2.4
master mode (to generate a genlock signal).
25 Setup the genlock crosslock mode. When disabled the camera will expect a tri-
level sync signal which matches the video mode (see point 15). For 4K / UHD
video modes this means the matching 2K / FHD video mode (e.g. 1080p30 for
21060p30), since there is no 4K genlock standard.
Crosslocking is possible in three different modes:
•Pal Black & Burst
•NTSC Black & Burst
•Other HD Mode
Pal and NTSC B&B are self-explanatory. In “Other HD Mode” you can select the
tri-level sync signal to which the camera shall lock (see point 26).
26 Setup genlock crosslock video mode. This combo-box is only enabled if
crosslocking is set to “Other HD Mode) (see point 25). You can select the tri-level
sync signal to which the camera shall lock.
25 Set the vertical genlock offset in lines.
26 Set the horizontal genlock offset in pixels.
27 Enable or disable genlock termination.
28 Field to enter the timecode.
29 Apply the currently entered timecode.
30 Get the current timecode of the device.
31 Hold the timecode. When enabled the device will stop incrementing the timdecode
on the SDI output. The internal counter will keep running, so if you resume, the
timecode will jump to the current value. This can be used to trigger external flash
recorders.
Note: How to setup the lens shading correction:
1. Point the camera at a homogeneous light source.
2. Connect the camera to a wave monitor and select a line in the middle of the image,
depending on the lens you use, you should see a decrease in luminescence
towards the edges of the image.
3. Enable lens shading correction, start with the Cosine4 Compensation, Offset and
Slope set to 0.
4. Now turn up the Cosine4 Compensation, this should correct the lens shading in the
middle area of the image, the edges will probably still be not ideally illuminated.
Make sure to not overcompensate, this will create a wavelike appearance of the
luminescence on the monitor.
5. Set the Offset to 0.5 and set to Slope to a high value like 1.5, you should now
clearly see where the compensation starts. Now adjust the Slope until you hit the
point where the luminescence starts decreasing. Finally decrease the Slope until
the result is not overcompensated anymore.
6. Make fine adjustments until you are satisfied with the result.

15 of 36 User Manual - ProVideo GUI v1.2.4
Please note that, depending on the optical lens used, the aperture and focal length have
influence on the lens shading, so you should use your default setup for configuring the
compensation. Also it might be helpful to turn off the auto exposure during the setup.
Note regarding ATOM one SSM500 cameras:
The ATOM one SSM500 slow-motion cameras share most of the options with the other
cameras. Additionally the following functions are available under “Output Configuration:
•Sensor Framerate: Setup the framerate at which the sensor runs. The combination
of sensor framerate and video mode determines the maximum slow motion factor
during playout (Trigger Mode only).
•Phases: Select how many of the SDI outputs shall be enabled. This impacts the
sensor framerate, e.g. when all 4 phases are enabled and 1080p50 is selected as
the video mode the sensor will run at 4 x 50 = 200 fps (SSM Mode only).
4.2 Lens Driver Tab

The two buttons on the right side of the box can be used to switch between the F-
Stops. These options works only correct, if the table, described in row 12
corresponds to the lens mounted on the camera.
12 F-Stop/ Position Table. This table contains the F-Stop Positions, that can be
determined with the Iris aperture box. This Table should correspond to the lens
mounted on the camera.
13 Iris F-Stop/ Position Table Templates. For some lenses a template can be chosen.
14 Delete Column. If the button is pressed, selected column of the table is deleted.
15 Transmit Table to Camera. If this button is pressed, the table is transmitted to the
camera, and the Iris aperture box is updated.
Note: How to setup the lens driver:
1. Select the connected lens in 1.
2. Click the Activate ens Button. In some cases the connected lens is not recognized
by the camera. If this happens, store all settings to the camera and powercycle the
camera.
3. If the lens is connected correctly the Software shows all options that are offered by
the connected lens. Not supported features are not shown in the ProVideo Gui.
4. For the correct aperture movement, use the corresponding template for the iris F-
Stop / Position table. If there is no corresponding template. The table has to be filled
in by the user. This can be done in two ways:
a. Manually fill in table
1. Drive the iris to the highest aperture value. Add the Value to the Table.
2. Insert the corresponding position in the table.
3. Repeat the two steps until all nine fields of the table are filled, or all values of
the lens are filled in the table. Not used columns of the table have to be set
to zero.
b. Edit the supported lenses file

17 of 36 User Manual - ProVideo GUI v1.2.4
1. In the folder where the “ProVideo.exe” is extracted a folder named
“tools_and_configs” is placed. Open the folder and the contained file
“Supported enses.txt”.
2. Add a new entry for your lens.
3. Increment the number of templates at to top of the document.
4. Restart the GUI for the changes to take effect.

1 Change the amount of recording buffers. Since applying a new buffer count
deletes all recorded image data you have to confirm this setting by clicking the
“Apply Buffer Count” button to the right of the spin box.
2 The table shows the current state of the recording buffers. It is also used to select
a buffer for recording or playback. To do so click on the row of the buffer you want
to select and then click on button 6 or 10 to start record or playback.
3 Free all buffers at once. Caution: This clears all image data!
4 Free the selected buffer, only enabled if a buffer is selected in the buffer table.
5 Select the Record Mode which can be either “ oop” to overwrite old data once the
buffer is full or “Once” to stop recording when the end of the buffer is reached.
6 Start Recording into the next buffer. If no buffer is selected the next free buffer
(with the smallest index) will be used, otherwise the selected buffer is used.
Disabled if no free buffer is available (use the free buffer buttons first to clear an
old buffer).

A new recording can be started any time (if a free buffer is available), even if a
recording is currently running. The switch to the new recording buffer will be done
without delay, no frames will be lost.
7 Stop recording, this switches the current recording buffer into “used” mode so that
it can be played back.
8 Select the Playback Mode which can also be either “ oop” or “Once”. oop will
resume playback at the start of the buffer once the end is reached, Once will stop
playback when the end is reached.
9 Select the Stop Mode which defines the behavior of the playback output if no
playback is running. Can be either of:
•ive: Show ive image (just like the live outputs)
•Black: Show a black image
•Test Pattern: Show a test pattern
10 Start Playback of the selected buffer. Only enabled if a buffer is selected in the
buffer table. Starting playback will enable the playback controls (see point 12 and
following).
11 Stop Playback, this will switch all buffers into “used” state and switch the playback
output into the mode that is specified by the Stop Mode (see point 9).
12 The seek bar shows the current frame position in the frame buffer that is being
played back. You can drag the seek bar handle to seek to a new position.
13 The skip buttons can be used to skip 1 or multiple frames at once (perform a
relative seek). They can be used while playback is running or while it is paused.
14 The mark bar shows the current mark-in and mark-out positions. The playback of
the buffer will loop between the mark-in and mark-out position. Drag the left or
right mark handle to adjust the positions.
To play back a part of the video that is not inside the marked area either re-adjust
the mark positions or manually drag the seek handle (see point 12) out of the
marked area.
Moving the mark-in position behind the mark-out position will reset the mark-out
position to maximum and vice-versa.
