No slideshow is needed:

• these slideshows always have single video that is not (directly) related to article. For example this article text is about banning Telegram by Iran gov., while video talks about previous news on topic — Russian gov. trying to ban Telegram.
• video in this slider always have same thumbnail img src="/assets/images/video_po_teme_sm.jpg", which is "related video" from russian which further proves my point.
• they do not work in any modern browser, only presented in old articles - a legacy thing that wasn't completely removed for some reason.

Great example that it's picked automaticaly:

https://tvzvezda.ru/news/vstrane_i_mire/content/201710241651-atqf.htm

Article is about cyberattacks on Odesa airport and Kyiv metro/subway, and video is Zuckerberg talking on topic of russian invasion into USA elections (which is often refered as russian cyberattacks).
