If they have a Chem taste or smell, you can leave the cap of for a day. Other than that, take it from someone who has tried many different methods, many. They are ready when they are ready. 2 weeks min usually, but not gospel. Dark cool location, not the fridge.
The guy in the video is a bit too chatty, but what he is saying is true. There are many methods, and I would recommend his method as the optimal one. Sonic cleaners don't work despite the claims to the contrary.
My one other recommendation, and I need to build one myself, is a shake table or other device to shake liquid.
Agitation is a must to both mix and ferment juice. You don't have to kill it with agitation, but it will save your arms. Cause generally you do need to do it for a good 5 to 10 min each, times how many bottles you have.
Those tiny bubbles are key
