Screen grabs of videos from streaming services

[DalekNim]

I’m trying to get some screen grabs from a show airing on Prime Video to do some cosplay costume design but when I pause the video and take a “screenshot” all I get is a black image. I’ve seen lots of threads where people post screen grabs from shows or movies to highlight costume or prop details so how ar3 they doing that? Can this be done on an IPad?

I had a similar issue trying to capture video and following this fixed it for me!
