      Whether I log in from the iOS client or the web interface, or view the RTSP stream in a viewer, I get the same results--stuttering video. I don't have any local storage on the device, so here's a snippet from the YouTube archived stream:

      https://youtu.be/GGPmEp_jZAA

      You can see the stutter as the seconds display flips over from :18 to :19. If you watch the live view during Los Angeles daytime hours (GMT-8), you'll see lots of bee activity, and it'll be more obvious:

      My RLC-410 works fine, with no stuttering:

      My RLC-423 also works fine, with no stuttering:

      https://www.youtube.com/user/IAmTheWaterbug/live

      Firmware on the RLC-411 is current at v2.0.0.1389_18081406, and I've tried rebooting it, reducing the data rate, etc., and nothing fixes the problem.

      The RLC-410, RLC-411, and RLC-423 are all on the same Ethernet switch, so the network infrastructure isn't the problem, and I have 50 Mbps up/down on FIOS, so internet access isn't the problem.

      Those first 2 live streams are supposed to be capturing a very important event tomorrow, so I'd love to get this fixed ASAP!

      Thanks!

        Here's an update, but this time the problem appears in the RTSP stream and not in the browser view:



        You can see my choppy arm motion, and you can see the last digit of the time display flicker as it goes from 37 to 38 to 39.

        This is not a VLC/client problem, because I have the exact same problem in other RTSP clients, such as ffmpeg feeding my YouTube channel. Look at the right side of this video:

        https://www.youtube.com/watch?v=OtjpylAEP8I&feature=youtu.be&t=2000

        This is not unique to one camera unit or even one model, as I've seen it on my RLC-423S as well as my RLC-411.

        This is not a power supply problem, because I have tried 3 different POE switches, and I've seen the problem on all 3.

        Sometimes I can "fix" it by changing to Color mode and then back to Black/White, but not always.

        All cameras have updated firmware as of 4/22/19. The problem pre-dated the firmware update. I've also tried factory re-setting the cameras, and that has not helped.

            Ugh. Still having this problem. See here:

            https://www.youtube.com/channel/UC7FH1CCSdg1-W9mlJ52cceQ/live

            As the bees run along the walls, they should run smoothly. But they appear to jerk, as though the camera is repeating frames.

                At long last I think I have figured this out. The culprit is the "3D Noise Reduction" feature in the camera. 3D noise reduction tries to average non-moving portions of adjacent frames in an attempt to reduce temporal noise. The non-RTSP stream received by the Reolink client does this properly, and outputs frames in order. The RTSP stream does _not_ do this properly, so it repeats some frames, which results in the stuttering effect that you see here. If you turn off the 3D Noise Reduction, then the RTSP stream works properly, although the bit rate goes way up. Other manufacturers implement 3D Noise Reduction properly in their RTSP streams.

                Please increase the framerate of the camera and check if the video will get more smoothly. If the issue remains, please send a request to support@reolink.com. They will help you with it. Thanks. Have a nice day!
