🧐 I don't know South African Sign Language, but I do notice a few similarities b/w it + ASL (ie signs like "to-look-forward [into the future]), as well as some ASL letters.

W/o being fluent in S.African Sign, I can only say the interpreter *looks* like she's keeping up w/ the source mssg (👍), and displays appropriate non-manual markers (facial expressions/shoulder shift/body mvmnts)-

You can compare it to this notorious fake South African "interpreter"- Even without knowing the language, you can see BIG differences b/w your video + this one...
