If the video you’re monitoring is jittery or is dropping frames, use the rendering rate video statistic to determine whether the workstation is the cause.

What you should know

Rendering rate is the comparison of how fast the workstation renders a video with the speed the workstation receives that video from the network. The rendering rate video statistic is made up of:
  • The speed at which the workstation processes video. This indicates how much load is on the workstation's CPU and memory.
  • The speed at which the network is sending video to the workstation.

Procedure

  1. Select the tile that’s playing video.
  2. Press Ctrl+Shift+A and check the rendering rate.
    Video stream statistics are displayed in the tile.

    If your rendering rate is "12 rendered fps on 19 fps", your workstation is processing 12 fps but receiving video at 19 fps. The workstation can’t process all the frames it’s receiving, which degrades the quality of the video that you’re monitoring.

    If your rendering rate is "12 rendered fps on 12 fps", your workstation is processing every frame that it receives from the network. Either the camera or the network is causing the video degradation.

  3. If your workstation is not rendering every frame it receives, lighten the load and check the hardware and its drivers:
    • Reduce the number of cameras that you’re monitoring.
    • Check the hardware requirements to make sure that the workstation can handle the load.
    • Check that the graphics card and video card drivers are up to date.
    • Check that the network card is up to date.
    • Check that all drivers are up to date.
  4. If your workstation is rendering every frame it receives from the network, determine whether the camera or network is the cause:
    1. Compare the second value to the camera's configured fps rate.
      If the rates are different, the camera is causing the video degradation. If the rates are the same, the network is not sending all the frames it receives from the camera.
    2. If the camera is the issue, check the camera's firmware.
    3. If the network is the issue, check the health of the network.
