Q: Am I allowed to stream the CBT, or record videos while playing?
A: The Closed Beta phases are not subject to an NDA so you are not only perfectly within your rights to stream if you wish to, but also encouraged to do so if that is something you enjoy doing."
Then from an Eterna Gaming interview with the producer

E.G: Will people be able to stream CBT content or will there be an NDA?
F.A: The first tests during in the testing phase will be under NDA, but in later stages when we open up to a bigger group, still during CBT, we wonÔÇÖt have an NDA in place.
Seems perfectly clear to me.
