There are another video in the same channel, and a link to the original files can be found here: https://disk.yandex.com/d/2NTD1HpTWBcf7Q

Completely agree with you, it's hard to tell because the footage is just crap, and the edit doesn't help. That's why the original footage has been provided in the video description.
