So what is the problem?

The NDI message tells you that you won't be able to use NDI unless you install the relevant drivers (which it seems you haven't done) If you don't want to use NDI, there's no need to install the drivers.

The recordPNM warning is totally unrelated (aka: please don't use the same ticket to lump together unrelated stuff; I close tickets once the main issue is fixed, which means that the other stuff will get close even if unfixed).

Anyhow the warning tells you that you are trying to record to a file with an unexpected file extension. Eg recordPNM can only reform pnm sequences, it cannot eg record .mov files.

There are various recording plugins available and green tries to find a "best match", but sometimes it cannot find a good match.

So is you are trying to record movies but have no proper movie recording plugin installed, it will eventually falls back to one that might not do what you want ... Which is what you are seeing here.

Sorry I didn't formulate well my question I couldn't find how to install the NDI from the link http://new.tk/NDIRedistV4Apple informed by Gem's message Still trying to fixed it. I found some drivers on https://ndi.video/tools/download/ but still no idea how to record it If it's possible to solve this issue in another way it would be great too. tks for all

ah i see.

is there any specific reason not to use the latest and greatest Gem? (at the time of writing this is v0.94-1011-g9beb39da7)

the link to the NDI download is taken from the SDK, so if Newtek decides to break their own links then we cannot do much about it. newer versions of Gem might build against a newer version of the SDK which might come with an updated (and still working) link. in your specific case (comparing the version you use and the version available via deken today), you can replace the "might* with "do".
