Good Evening,
We recently added an NDI camera(Avkans LV20N) to our Flo motorsports production at our local track. First week the shot had a slight stutter so I switched from HX3 to HX2 and then dropped to 30fps but still 1080. The video was pretty much rock solid all night. End of night I was exporting my instant replay recording and nothing from the NDI camera recorded. From what I could read up on the 30fps was different than what the session was recording so that was why it dropped.

Week two, I stayed with HX3 60fps a little longer but was getting fairly noticeable stutter. Finally switched over just before the event began to HX2 60fps and it was slightly better but still a noticeable stutter. And at the end of the night when exporting the instant replay recording the NDI camera did not record again. I use the video recordings for ads for upcoming races. At the track I opened NDI Studio Monitor and the video was smooth as butter but the straight ndi feed in vmix it was a hot mess.

Tweaked some settings for gpu use in vmix and in the system to test at home. Hooked camera up tonight and Studio Monitor was once again silky smooth but Vmix is stuttering. Any ideas of what might be going on? My vmix cpu/gpu usage doesn’t show anything out of whack during operation. We already have a second camera but waiting on portable power source shipping in to power the remote location and I also want to have this figured out before we add another camera to the mix.

One thing I am considering for this week is opening the camera feed in Studio Monitor and importing that feed for the production. That will also give me the option to record the video, although I won’t be able to use in instant replay. When I import the studio monitor feed into vmix and the straight ndi camera feed there is no comparison, the studio monitor feed is far more stable.


Much appreciation in advance for any and all help.
Thanks,
Nick

First test was a huge success. Opened Bridge and transcoded to Full NDI, input to vmix through Bridge feed, zero packets lost and a good picture.
We also have a second camera to install so I went ahead and hooked it up as well. With both cameras transcoding full NDI through Bridge, both loaded as vmix inputs through Bridge, zero packets lost and two good pictures. I tried a little something and opened two instances of Studio Monitor and recorded both streams while all this was going on, and all went well.
Thanks a bunch Kevin!
