In the video clip, I see 6 specimens of Demodex folliculorum (two of them embedded in the follicle). According to the length of their body, they are most probably the nymphal stages.

DEMODEX

This micromite is called Demodex
It can be found in many acarology text

Not designed to move very far
8 stubby legs and the shape of a cigar

It dwells in the follicles of old ones brow
And if you didn’t know this by now

Usually nonpathogenic but occasionally is thought
To cause rosacea however this theory is fraught

with controversy. We have only to thank Herr Dr. Jake Henie
Who discovered this mini monster dwelling within Thee
