How to get a frame from a vk.com video?

Question

Video processing

Is there any way to get a frame from a video using such a link? vk.com/video_ext.php?oid=-29058619&id=168440714&ha...
Or via a direct link to a video like this: cs534223v4.vk.me/u16408733/videos/6fe6b6f0c0.240.m...
The whole problem is that the frame , which VK itself offers, I don’t need, I need a different, unique frame, i.e. a prerequisite is to get a frame somehow yourself.
The easiest option is to just download the video and ffmpeg'om pull out the desired frame, but downloading the video takes a long time, especially if there are a lot of them and you need to get a thumbnail for each.
Therefore, I ask you, what are the known possibilities to get this very frame (accuracy is not important), NOT downloading the video or downloading, but not the whole thing? More or less automatic.
