![]() I use three PTZ NDI cameras (AlfaTron ALF-20NDIC). The first is a Lenovo i5 laptop, 8GB RAM and the second (new PC) is a micro desktop HP model using an i7 processor with an Invidia T1000 GPU and 16GB RAM. I have tried two computers, both running on Windows 10. When starting up OBS, the output lag is acceptable but it slowly becomes more apparent the longer OBS is open. ![]() To clarify, the issue is not audio / video syncing but a growing latency issue with OBS program output to local TV monitors via HDMI within a house of worship venue. I have been having the same issue with growing latency with NDI video output using OBS. (Sorry in advance that this post is not very technical). The best solution of course wouldbe a solution within the plugin. Of course it is not a solution to resync the camera every 5 minutes, especially when the camera is on air. Obviously that shifting latency is an issue of the OBS-NDI plugin.ĭoes anyone out there made the same experiences as I did and is there a solution/workaround? So after 3 hours of operation my NDI-camera is about 720ms late which of course is not usable.Įvertime I change the sync for the NDI-camera from source timing to network or from network to source timing the camera is back in sync again. ![]() I used the OBS-NDI plugin (Windows 4.9.0) and added 80ms delay within OBS for that source to match my timing.ĭuring my transmission I got aware of the fact that the NDI-camera run out of audio/video synchronisation.Īfter the transmission I did some tests with the following result:ĭuring operation the NDI-Source (camera) has a shift of about 40ms every 10min. This camera is a PTZ-camera operated via NDI. I added a second camera to my setup for a streaming event I had to do 3 days ago. ![]() I adjusted the audiolatency in my audiomixer to match the latency of the camera, everything worked fine. I did a streaming event 3 months ago with an USB-Camera I extendend with an UTN (USB to Network) –Server and a dedicated audio mixer connected to my computer via USB (operated with the ASIO-pluginfor OBS) I have got a problem with the intergration oft the obs-ndi plugin which might have been discussed already, I am not shure:
