Answer on answer from Giacomo

You are can't used this link, because it not contains on original page, it is contained in iframe another domain. But IV not supported @inline iframe for different origin (see pictures below), you don't get this link, so you inserted it manually. In your actions there is no software algorithm that can be implemented in IV on xpath, you just inserted the final format of the link into your template. But since this template is constantly changing and you can’t track it in any way except manually, I think that the video on this site should not be supported, since there is no way to reliably determine the final link to the mp4 file.

And I insist that Admin reject both of our templates, and insisted that the video here should be marked as @unsupported.
