3.7.5 Several Problem solving
1) Whether NDI|HX has significant latency in using vmix ?
A: 1.The client configures the cache, causing the latency to increase.
2.Set the frame rate to 60 frames can reduce latency.
2) NDI|HX can use vmix to print out the picture normally.,while the screen will be black during the use.Can PTZ
be controlled during the process?
A: 1.The computer configuration problem leads to the failure of drawing. Please refer to the minimum
configuration provided by NDI's official website.
2.When vmix obtains the NDI source, NDI|HX will request the key frame. If the key frame acquisition time is
greater than 100ms, it can only be solved by restarting the camera.Therefore, it is recommended not to fetch
other network streams, such as RTSP, RTMP, page preview, etc., when using NDI 60 frames.
3) How long does the NDI|HX delay?
A: The tested average delay is about 130ms, and the lowest delay is about 80ms when NDI|HX’s using
configuration is 1920* 1080 4096kbs 60fps and video output configuration is 720P60.
Test software:NDI Studio Monitor,turn on low latency mode.
4) How does NDI|HX modify network audio and video parameters?
A: Refer to the section of NDI|HX Network Video and Audio Encoding Parameters Configuration.
5) Can NDI|HX search the source but not get the image?
A: Refer to the section of NDI|HX Environment Configuration.
6) Can NDI|HX normally print out pictures with vmix?
A: vmix23and later version can print out pictures normally.
7) Which format does NDI support, NDI|HX or FULL NDI?
A: NDI|HX compression (h264, h265) is supported, while FULL NDI compression is not supported.
The H265 video compression format is supported only with the latest NDI4.5.2
