Based on the bare minimum of information I have to go on, sounds like either the rings are all blown out or the head gaskets are gone.

How about tell us about your car, what you've done to it, maintenance done, what happened just before this started happening, the color of the smoke, etc

Looks pretty spooky. I can't be sure from here but the thick and lingering nature of the smoke looks like oil smoke. Pull the spark plugs and look at them (post pics of all 8) and get a compression test.
