exacqVision Export Video File Types

Video may be exported from exacqVision in different formats. The table below illustrates some of the differences in these formats.

File Type Features Table

Multi-Camera: For the purposes of this article, multi-camera means many camera streams are combined into a single exported file. When exporting as .MOV, .AVI, or .MP4 each stream will end up as its own file.

Self-Playing: The .EXE file format bundles the exacqVision ePlayer into the file. This allows the file to be opened and played back on any Windows desktop or server operating system. This file format does not play natively on Ubuntu/Linux or Mac systems.

For more details on .AVI and .MOV usage and codecs, please refer to Article 1925

How do I save a video clip to an executable file that I can send to the police?

The ExacqVision Desktop Client application can be used to export video and audio to an .EXE executable file which packages the ExacqVision ePlayer with it to become a self-playing file.

The fact that the .EXE export has the ePlayer packaged with it makes it ideal for sharing with law enforcement who may not have access to ExacqVision software. For more details on the differences between the options for video file exports, refer to Article 1894.

Exporting using the Desktop Client

To export an .EXE file from the ExacqVision Desktop Client, click the Search icon from the toolbar. Note, the user account you are connected to the server with must have Search Privileges.

Use the Search options to select the camera(s), audio devices, or serial data devices for your inquiry. Set the Start and End times for your search range. For more detail on the variety of methods you can use to perform searches, or using bookmarks and cases, refer to the User Manual or User Training Videos.

Use the Mark Start/Stop icons on the search toolbar, or right-click the timeline to select Mark Start/Stop, for the portion of timeline you aim to export.

You may use the Download and Export icon on the top-most toolbar, the Download and Export icon on the search toolbar above the timeline, or right-click on the timeline and select Download and Export Video.

In the dialog window that opens, provide an optional File Name for the export and choose Standalone Exe (*.exe) from the Save as type selector.

The resulting file can be shared for playback on any Windows computer without ExacqVision software. Note, that if you intend to email this file to a third-party, many email systems will prevent .EXE files from being sent or received so you may need to transmit or share the file using another method.

Refer to Article 2639 for information on file verification (watermarking).


Using CLI commands to Export files directly from storage to executable files

While the graphical client solution above is preferred, in the event this cannot be performed graphically or you need to script bulk .EXE exports directly from your storage drives, the following method may be applied and requires the input file to be a .PS file type.

Note, resulting .EXE file exports may only be played back on Windows machines regardless of whether they are exported from a Linux machine.

  1. Determine the directory in which the .PS file to be converted is located. Refer to Article 393 for information on recording directories and the file naming convention used.
    <br>
  2. On Windows, open a CMD command window. You will likely need to open CMD with Administrator privileges.

    On Linux systems, you will open a Terminal command window.
    <br>
  3. The default locations of the ePlayer are as follows:

    Windows: C:\Program Files\exacqVision\Client\ePlayer.exe

    Linux: /usr/local/exacq/client/ePlayerPro
    <br>
  4. Issue the following command, where i, the input file, is the path and name to your desired .PS file to export, and o, the output file is the desired name of the exported file.
    Replace “filepath” with your desired directory path.
    Replace “inputfilename” with the file name of the .PS file you are referencing for export.
    Replace “outputfilename” with your desired file name.

    Windows: “C:\Program Files\exacqVision\Client\ePlayer.exe” /c /i”filepath\inputfilename.ps” /o”filepath\outfilename.exe”

    Linux: /usr/local/exacq/client/ePlayerPro -c -i”filepath/inputfilename.ps” -o”filepath/outputfilename.exe”
    <br>
  5. The resulting file can be shared for playback on any Windows computer without ExacqVision software. Note, that if you intend to email this file to a third-party, many email systems will prevent .EXE files from being sent or received so you may need to transmit or share the file using another method.
