Help me please

I shoot video on YouTube and voicing updates DEW blogs for its not a big audience.
I have a question.
Is it possible to use materials from DEW blogs developers?(
Screenshots and videos
They are public?
Thank you for your attention)

As long as you give credit where credit is due I can’t see why this would be a problem.
Infusednz is a youtuber who does the same I believe, you can always ask him.
