Live signals (capture and NDI) stutters badly

Hi,

Maybe someone has experienced this as well and found a solution.

I'm on a show with a server set up by my client running WATCHOUT 6.5.5 and Windows 10. It works fine except that a live image captured into a Datapath VisionAV SDI card or through NDI stutters badly on this server. It looks as if the first 10 seconds or so are fine and then the stuttering starts. I deleted the NDI driver and WATCHOUT and made a fresh installation of WATCHOUT 6.7 but this didn't cure the problems. I've used both capture solutions very often before with my own servers but never had this experience.

On the production computer the NDI signal looks smooth in the stage window. We could rule out network issues too since also with a dumb switch in between it didn't change. Since the capture card shows the same problem I assume that something in the server is configured wrongly. Any idea what to check or look for?
We also tested the NDI signal with the NDI monitor tool on a third computer and this looked fine too.

Maybe someone has come across this issue and was able to solve it.

Hi Rainer,

Strange issue...

I've already seen some NDI stream shuttering when using YUVY pixel format, switching to BGRA solved the issue in my case. I think it was the NDI sender that was configured for BGRA and asking for YUVY takes him too much work.

But that's stange you see also the inssue with the live input.

Whish you good luck.

Hi Benoit,

Thanks for your input. I tried to send the NDI signal from a Birddog Studio NDI and the Newtek Scan Converter. Both worked on the production computer and a third PC but not on the server. Since the same happens on a traditional capture card, it feels as if some core component used for rendering the live feeds is broken or missing on this machine.
