@joseph_1979 I thought the H265 stream didn't have the same issue, but I just needed to watch it a while longer for the distortion and artifacts to return. I finally gave up on Agent DVR after I tested the 4K stream with no issues in Milestone XProtect, so I should be good to go between that and Blue Iris, even though I prefer the interface of Agent DVR.

It had been a few weeks of troubleshooting, so I think I had changed every possible setting in Reolink client and in Agent DVR. Some of the changes made to cam settings in Reolink client:

• Bit rates
• Interframe spacing/I-Frame Interval
• Frame rates including constant/variable
• Anti-flicker
• Disabled motion detection
• Factory reset
• Tested with different cable and switch port

On the Agent DVR side, I lost count of the settings and streams that I tried. I think if it's a camera, decoding, playback, or other setting in Agent DVR that could possibly have an impact of the issue, then I probably changed it at one point or another at least once. Definitely was using GPU for decoding/live view but still changed those setting several times including trying software decoding, and also motion and people detection including disabling it.

The one thing I noticed is no matter which settings were used in Agent DVR, the live view in always looked far smoother and overall better in Reolink client, Blue Iris, and Milestone than in Agent DVR even when there were no artifacts in the stream.

@joseph_1979 Much appreciated. The H265 URL you posted seems to be displaying way better than the others. I'm in the process of testing and will report back. Here are the ones I had previously tested:

rtsp://192.168.0.X:554/

rtsp://username:password@192.168.0.X:554/Preview_01_main

I've been having issues with my Trackmix PoE for a couple weeks now and have been unable to find a solution: The 4k stream has major purple, green, and gray distortion/artifacts that make it unusable for live viewing in VLC, ZoneMinder, and Agent DVR, but works fine in the Reolink client. 4k footage recorded from those apps tends to work fine, but not always. 

I tested Blue Iris this morning and it immediately picks up the 4k stream and plays it without issue in great quality. Judging by the ports and settings in Agent DVR vs Blue Iris, it looks like both are using RTSP (port 554 and 8000). The profile in Blue Iris is Profile000_Mainstream, but I'm not sure if that's part of the URL or just the profile name, and I can't find the full URL it's using... only the IP and ports. I'm wondering/hoping Blue Iris is simply using a different stream URL and if I can find that I'll be good, but so far every URL I've found using Reolink documentation and the ones found in Agent DVR give the same issue of distortion. 

Issue persists after upgrading firmware and also factory reset. 

Same problem regardless of type of playback decoding used in Agent DVR.
