    Info
    titleNote

    It isn’t recommended to use videos compressed by the Wavelet codec, as their use significantly increases the load on the Server.


  7. Click the Apply button (5).
    If Intellect does not find files for playback within 1 one minute after clicking the Apply button, the file search will be interrupted.

Note
titleAttention!

The selected folder should not contain the video recordings of the internal Intellect format and AVI-files at the same time.

It is recommended to use one video recording and specify the folder containing only the recording or the path to the file. If you need to use several video recordings, select the recordings with similar codec and resolution. This will help to avoid delays in Intellect work when switching between the recordings.

...

If there are several files in the folder, they are to will be played back in the order set in the latest modification. Files can also be sorted by name and time of creation during playback. The sorting order is set by the VirtualGrabberSortMode registry parameter (see Registry keys reference guide).

When playing back the files, the system sends events to the Debug window displaying the playback status – (see CAM Camera). There are also reactions for controlling video recordings playback in virtual Video Capture Device using the scripts (see GRABBER Video capture device).
