hey, Im looking for help

My work is trying to setup a live stream and we purchased a HD60 s and we are connecting a hdmi camera with audio we would like to use. we can live stream for 5-10 min then we get a sudden audio loss, it will come back in time but it will cut out again within about that same time frame.

If anyone could help it would be greatly appreciated

No output session in the log.

Open OBS. Begin an output session (stream or recording). Observe your problem. Stop the output session. Upload the Current loq without quitting OBS.

That said, it looks to me like you are overloading your machine. Over the course of about 18 seconds, the machine falls behind in processing this particular media source so badly that it fills the audio buffer causing a delay of 1 second; it would not be surprising to expect that in 5-10 minutes the same process would cause OBS to be unable to continue working properly.

As far as I can see, yes, but the log is not complete and contains no performance data from when OBS is actually encoding video, so you may have additional problems I cannot see.

This indicates your machine is unable to keep up with processing the feeds from your NDI source and your elgato. You may wish to target a different canvas resolution/framerate (ie, choose between 1080p30 and 720p60. You are scaling down to 720p, but keeping the canvas as 1080 means OBS is rendering frames at that size prior to encoding.
