Remove jitter from live video

Live video may sometimes jitter due to minor bandwidth or network issues. Jitter appears as irregular movement, such as choppy video when a person is walking. To smooth out live video, you can add a small buffer before displaying it in XProtect Smart Client. Although this buffering introduces a slight delay, the video appears smoother.

Important considerations

• Delayed ressponse: avoid using video buffering for pan-tilt-zoom (PTZ) cameras if you need instant response for joystick operations, because the delay will be noticeable.

• Memory usage: Video buffering can increase memory usage, so keep it as low as possible.

To remove jitter:

1. 在工作区工具栏中，选择设置。

2. Select the view and the camera view item with the live video stream you want to smooth.

3. On the Properties pane, under Video buffering:

   • Select Use default video buffer to use the buffer defined by your system administrator. See also 应用程序设置.

   • Clear Use default video buffer and expand the Video buffer list to select a buffer from None to Maximum - (2 seconds).

     To apply the same settings for all camera, hotspot, and carousel view items, define the settings for one view item, then select Apply To All in the Properties pane.

4. If you don’t see Video buffering on the Properties pane, in the Settings and more menu, select Settings, and on the Functions tab, set Setup > Edit video buffering to Available. See also 功能设置.

5. 再次选择设置可退出设置模式并保存修改。
