After downloading, please run the executable installer file. The installation process needs admin rights exclusively to write into the ProgramFiles directory – so you can safely confirm the appearing User Account Control <UAC> dialog.


If Windows SmartScreen shows an alert, just continue with execution as follows:



Then just follow the installation instructions, which will guide you through the complete installation process.


Please observe, that you will be asked to select an installation folder twice:

  • The first one is for the Software itself (usually: “C:\ProgramFiles\SET Video Review”)
  • and the second one for the recordings, exports and archives to be stored. (usually: “C:\ProgramData\SET Video Review”)

It is not recommended to store the recordings in the ProgramFiles Directory – so please use the preselected ProgramData directory, or select something like your personal video directory for example. It is advisable to choose fast storage types like SSDs, but generally you can select any storage type you prefer (see System Requirements).

To activate SET Video Review you have to obtain a license via the sportdata online shop:


You can choose between a 3-year, 1-year or event based license. For all license types the software can be installed and used on as many computers as you want. When the license period has expired, SET Video Review will run in DEMO mode again. The DEMO mode has no functional limitations, but recordings can be no longer than 15 seconds.

You will receive a license file after purchasing one of the licenses mentioned above. This file is needed to activate SET Video Review and unlock the recording-time limitation. Therefore, open SET Video Review and start the License Manager via the top menu bar. Follow the instructions of the License Manager and select the received license file when requested. If the selected license file is valid, the License Manager confirms the successful activation and SET Video Review is ready to be used without any limitations.

Useful information concerning a current task are displayed in the Panel Status Bar of each active Viewer Panel. For more details see the Preview, Recording and Review sections.

Viewer Window

The Viewer Window basically has the same controls than the Viewer Panels, except the two pickers and the Sync Checkbox. The Viewer Window appears when double-clicking into the viewport of a Viewer Panel and is usually used in (borderless) fullscreen mode.

Recordings List

All recordings stored in the configured Recording Directory are listed in the Recordings List on the left. As recognizable in the picture below, every parent item consists of up to four camera recordings, which are made visible by expanding the parent item. The parent item is named with the date and time of the recording being started.


A right-click on a parent recording item (or multiple selected items) shows  a popup menu with the following entries:

  • Delete Delete (DEL key) – Deletes the complete recording(s) (all containing camera recordings).
  • Archive Archive – Moves the complete recording(s) (all containing camera recordings) to a desired location. Later importing via  File – Import  is possible.

A right-click on a single camera recording shows  a popup menu with the following entries:

  • Delete Delete (DEL key) – Deletes a single (or multiple) camera recording(s).
  • export Export – Generates an MP4 file of the selected camera recording, stored to the desired location. Multi-selection is not supported yet.

Control Panel

The first step before getting productive should be ensuring that everything is set up correctly. Therefore, SET Video Review provides the Preview modeIt connects to the selected camera and shows the live video stream without recording it to your storage device. So, if the Preview works without any problems, most likely the Recording also will succeed. But please note, that the Preview mode is not supposed to estimate the system performance (due to not reading/writing any data to storage).

Step by step

  1. Select the desired device from the Camera Picker campicker
  2. Select the desired resolution from the Resolution Picker resolution_picker (except for IP cams)
  3. Click the Preview button preview_icon in the Control Panel to start the Preview
  4. If the connection succeeds the Viewer Panel becomes green bordered and you should see the live video.
  5. To stop the Preview, click the same button again. stopprev_icon

If problems occur, see the Troubleshooting.

If the Preview works, SET Video Review is basically ready to start recording – providing that the Recording directory is set correctly, of course.

Step by step

  • Perform the Preview step, if not already done.
  • Click the Record Button rec_icon  (or SPACE key) to start recording.
  • Click the same button again stop_icon  (or SPACE key) to stop recording.

Attention: A high number of dropped frames per second indicate an overloaded system. See Troubleshooting.

After the Recording process, SET Video Review immediately starts the Review mode. The Viewer Panel(s) automatically show(s) the current recording and sets the Review Slider position to:

NumberOfImages – configuredFPS * 7

So now the Review process can be started by the user. Basically, three different workflows are common to be used – exclusively or in combination:

Working with the fullscreen Viewer Window

One method of operating is by using the fullscreen Viewer Window. It can be configured via the Preferences to be viewed completely borderless and/or automatically resizing the current recording to fit into the Viewer Window’s viewport.

Usually (e.g. when doing (time) critical video reviews on sport events) the responsible reviewer decides upon the best view, which then is made fullscreen by double-clicking into the viewport of the chosen Viewer Panel. After a decision is made (or whatever is required), the Recording can be started directly via the SPACE key. Alternatively, the Viewer Window can be closed by doubleclicking into the viewport or pressing the ESC key – followed by clicking the Record Button rec_icon to start Recording.

Working on the single Viewer Panels

Directly using the single Viewer Panels enables multi-angle reviews or analyzations. The Sync Checkbox sync additionally allows to synchronize the Viewer Panels. So for example altering the Review Slider position, viewing important moments frame-by-frame or starting a playback – everything (except zooming) will be applied to all synced Viewer Panels simultaneously.

Working with four-in-one video material

If specific hardware setups deliver four-in-one video material, the appropriate Preferences option “Quarter view in fullscreen mode” should be selected. With this option enabled, opening the fullscreen Viewer Window automatically zooms to the quarter where the corresponding double-click occurred.

SET Video Review is fully integrated into the SET Software Framework. Thus, if you’re using it for instant replay, it is possible to directly track results via a connected SET Point Panel. The Point Panel then can use its built-in visualization to view the result on any kind and number of display units, while besides storing all the information in the central SET database automatically.

Requirements:  “Show SET result tracker” checkbox is selected and a valid “SET Client VR Result URL” is set in the Preferences

Step by step

  1. Ensure correct SET Preferences and a working network connection.
  2. After a decision has been made, click the appropriate Result Tracker Button in the Control Panel.
  3. Watch the Main Status Bar for relevant information

SET Point Panel integration

This section shows how the result tracking feature of SET Video Review is integrated in SET Point Panel. So, the following screenshots come from SET Point Panel – not from SET Video Review itself!

Moreover, the SET main software supports electronic Video Review Requests by Coaches via the SET Scoring App (Android Application)


Exemplary sport: WKF Karate

Point Panel VR-Status Icon

The VR icon in SET Point Panel shows if the red/blue coach is allowed to do a protest. (If enabled in SET: Settings->PointPanel)

Point Panel VR Action View

If a video review is requested, the screens show the VR View, including the kind of score requested – as well as the result (Accepted/Denied) submitted by SET Video Review.

Preferred camera resolution is not listed in the Resolution Picker

  • → The selected device does not support the resolution, so a different one must be chosen.

Connection failed

  • The Viewer Panel becomes red bordered and will probably show an error message in the Viewer Status Bar. Common reasons and possible solutions are:
    • Device(s) powered off → Check power status and switch off/on if necessary.
    • Cable/Wireless connection problem → Unplug/plug  cables or switch WLAN off/on if necessary.
    • Wrong FPS configuration → Check the camera’s FPS support and change the Preferences.
    • Device is currently used in another application (e.g. Skype) → Close all not needed applications.

Viewer Panel shows black image instead of live video

  • Capture devices sometimes send black still images when not receiving any input signal → Check the HDMI/SDI/.. cables delivering the source video signal.


Recording performance is low (e.g. indicated by high number of dropped or duplicated frames)

  • System performance too low  → Check the System Requirements. Choose lower resolution and/or lower FPS and/or decrease number of cameras.
  • Another task slows down your computer in the background → Close all not needed applications and watch out for CPU intensive tasks e.g. with the help of the Windows Task Manager.
    • If tasks named ‘ffmpeg.exe’ are running while SET Video Review is NOT RECORDING and NO EXPORT was made, please 1) close SET Video Review and 2) close the ffmpeg.exe task(s).
  • Recording performance is low although Preview is working well → This can happen because the Preview is NOT an indicator for a sufficient system performance! (due to not reading/writing any data from/to the storage device)

Connection failed

  • … see ‘Connection failed’ in the Preview Troubleshooting above.

Viewer Panel shows black image instead of live video

  • Capture devices sometimes send black still images when not receiving any input signal → Check the HDMI/SDI/.. cables delivering the source video signal.

Frames per second (FPS)

Determines the preferred number of recorded images per second for all video sources.

Please note that a camera might not support your configured FPS. In this case, the recording will not succeed – indicated by a red bordered recording panel and an error message at the panel’s bottom.

Maximum recording time [seconds]

After the maximum recording time, SET Video Review stops the recording to avoid wasting disk space.

Delay view while recording [seconds] (new in v 1.1.)

Set the number of seconds of view delay while recording. This allows you to review actions quickly without stopping the recording.

Recording directory

Path to the directory storing the recordings as JPEG files in an accurately defined folder structure.

Export directory

Path to the directory storing MP4 exports. You will be prompted before each export though, using the configured export directory as a starting point.

Archive directory

Path to the directory storing recording archives. You will be prompted before each archiving process though, using the configured archive directory as a starting point.

Quarter view in fullscreen mode

This option is useful for hardware setups merging four video sources to one single input signal: Opening the fullscreen mode while reviewing automatically zooms to the quarter where the corresponding double-click occurred.

Autom. fit image to screen in fullscreen mode

When opening the fullscreen mode while reviewing, the zoom factor is automatically adjusted to maximize the image size of the recording without cropping it.

Undecorated fullscreen mode

Hides the window borders to maximize the available viewport of the review fullscreen mode.

IP Cameras

SET Video Review supports wired (LAN) or wireless (WLAN) IP cameras using various protocol types and codecs. IP cams must be added manually via Edit – Preferences by providing the camera URLs in the IP-Camera section.

Adding new cams is done by entering a URL in the URL text field at the bottom and clicking the Add button. If the URL is valid, it is listed in the area above. After closing the Preferences window, the newly configured IP cams will be added to the Cam dropdown lists.

IP cams

To remove a cam, select the appropriate cam in the list and click Remove.


Configuring IP cams by using parameters is possible by adding so called GET parameters directly to the URL.

The support and correct use of those parameters depends on the camera type and model. So please read the camera’s manual or ask the manufacturer how to configure the camera by using GET parameters.

Examples (unspecific):

Configured resolution:  http://my.webcam.com/mjpg/video.mjpg?resolution=1280×720
With credentials:  https://admin:password@

Examples (specific):

RTSP, public AXIS webcam:  rtsp://
HTTP, public AXIS webcam:

Supported protocols & codecs

SET Video Review makes use of the powerful FFmpeg project, and thus profits from its numerous supported protocols and codecs.

To mention only a few important ones:

Protocols: HTTP, RTSP, …
Codecs: MJPEG, H.264, …
