Error on older video Invisible Inc QL

Not sure if this one has been spotted already in another thread & didn't spot one. Tried on both Firefox & Microsoft Edge this morning & got the same kind of error playback on both browsers. Hope this helps & been going through the older quick looks on games I didn't get that I might not have spotted back then.

The Us vs. Them Overwatch video is the same way

I also had the same issue with Immortal Redneck Quick Look at first and it looks like the issue was, that the video isn't on youtube. I can't find the Invisible Inc. video or the Us vs. Them Overwatch video on youtube either so that does seem to explain it.
