On the commercial side of the industry we're already seeing a lot of self-recording happening with directors remotely guiding actors through their paces - while the actor lights the scene (usually in or adjacent to their residence), shows off wardrobe selections, dresses the "set", does their own hair and makeup, positions the camera (either their own phone or something provided by the production) and records and uploads the footage. Needless to say, under normal conditions everything but the performance would be handled by crew, but that can't happen now - and probably won't for some time until there's either a vaccine or rigorous, fast, effective and widely available testing - but of course producers and advertisers are balking at paying the actor extra for all that additional work, which can sometimes add hours or even days to the shoot.

As for the sequestration idea, yeah, it's being floated around, but again producers aren't really jazzed about it, because of all the additional cost it will impose, and they're already trying to figure out how to budget for constant testing, equipment and location cleaning, meal prep, and all the other things required for production in an environment where even the slightest breach of protocol will require a "back to one" approach for the entire cast and crew.
