I suggest that your video policy needs some rethinking and revision.
I don't have ad blockers operating, so I can see the videos. But, they are running as soon as I open the article and they are showing ads, so I generally do not stop to watch them as I scroll past reading the text. Once they finish running, it is not obvious how to get back to the beginning to watch the intended content. (Hint, the easiest way is to close and reopen the article.) So, when you scroll back and see a black box, it just looks like another one of those crashed ad boxes that litter so much of our screen space these days. Many people probably do not even know that those windows have content related to the article.
And , with 2 long ads preceding every video, the content of the video is often shorter than the total for the ads.
And, long videos seem to have ads inserted into the middle of them, too.
As a result, I rarely watch the videos on this site. Which means you are past the point of diminishing returns on adding ads to your videos.
But, unless a moderator here tapes this post to a brick and throws it through the window of the editor's office, the people making those decisions probably have no idea how badly they are performing.
