I’m asking this because, I have seen a video from YouTube and I need someone to identify it and tell from where was this video taken from. And I’m having problems with finding this. Can you please ad this tag?
No, we should not.
Some sites accept "identify this" questions, but I don't see how that would even be remotely within the scope of this site. This site isn't about videos; it's about web applications. That there are web applications that show videos does not automatically make video content on-topic here.
