    I am trying to upload a file to virtual camera, but the following error is shown:

    Selected file does not have timestamp
    Only video files with correct timestamp are supported.

    How should I process a video file to fix it?

    Hi Andrii,

    Our apologies for the delay in our reply. 

    As the error mentions, the file needs to have a correct timestamp to be supported. 
    If the timestamp isn't available, you can't add it as a virtual camera and can add it as a local file only with the following instructions:

    When Nx Witness starts, it automatically indexes the designated local media folders and displays them under Local Files in the Resource Tree. The default media folders (customizable) are:

    • Windows: C:\Users\<username>\Videos\Nx Witness Media
    • Linux: /home/<username>/Videos/Nx Witness Media
    • Mac OS X: /Users/<username>/Movies/Nx Witness Media

    To add or remove a Media Folder

    1. Open Main Menu > Local Settings > General tab
    2. In Local Media Folders section, click Add and choose the desired path.
    3. To delete a media folder, select the folder from the list and click Remove.
    4. Click OK when finished or Cancel to discard changes.
    5. Nx Witness must be restarted for media folder changes to be in effect.

    When Nx Witness restarts, files in the listed folders will display in the Resource Tree under Local Files.

    To open local files that are outside the Media Folders

    To view local files that are not shown in the Resource Tree, use one of the following:

    • Drag-and-drop a video file(s) or a folder from Windows Explorer to copy it into the Nx Witness Viewing Grid.
    • Go to Main Menu and select Open > Files (Ctrl+O) then select the file(s) to be opened
    • Go to Main Menu and choose Open > Folder then select a folder to be opened
    • Right-click anywhere on the Viewing Grid to open the context menu, select Open > Folder then choose a folder
