Now let's open site's video section and test a few from the list against my template:

They all do work!

I've tested quite a number of video pages and couldn't find a page that would not work.

So it seems like the issue is specific to that specific page. And I appeal to the exception regarding one-off cases.

Furthermore, this reveals an issue with video captions in reporter's template:

First, note how the website formats video pages. It always duplicates the title above the video adding a "Video:" prefix:

Note also that the true caption is below the video.

Now let's see how the reporter's template handles it:

Video: Chế dép tông cực đỉnh từ keo nến: Nguồn video: WEAREX 

Having the title duplicated is not an issue on it's own, of course, since it's in the source.

However:

1. It's not a caption
2. It was above the video with a colon (:) indicating that it says about the following thing. Now it's below the video and attached to the true caption. Now it looks like it says about the following text, which is not true in the source.
