I can tell you have gloriously wonderful information, but I apologize for saying I cannot understand your English. I've turned on the RU-vid Closed Captions, but it is merely a computer with voice to text and it doesn't understand either. I would like to tell you about a feature with RU-vid where you can write the Closed Captions--letting each sentence appear while you are saying it. It's a bit more work but if you would like more "Likes" and subscribers, I think you'll find it well worth the effort. If you're a college or university professor, you might be able to have a student earn credits for doing this. The option for this is in the screen where the video is managed. Again, I apologize for my limited familiarity with English variations.
