Bugs on plants

Hey guys
I need help with an infestation. I have a glass cabinet where these tiny mites can be seen on my plants (attaching a video). I thought they're soil mites, as they're too big, fast and don't make webbing. My plants seem to have some damage though.

Ive been fighting spidermites for few months and they sometimes just reappear. I have applied predatory mites to help with that (phytoseiulus persimilis) two days ago and acaricide which shouldn't kill the predatory mites. My current guess is that these fast ones might actually be soil mites which don't damage the plants and the damage on my plants actually came from the spider mites.

Can you help me with what it might be? Sadly I couldn't take a better video.
