Just knowing these guys and what they like, that's what Live Rosin is! The day of harvest you trim up the buds and buck them off and put them in a bag in the freezer. You let them freeze for 24 hours and then either ice wash or dry ice shake the buds and extract the hash.
With ice water hash, yet to freeze it first and a freeze dryer is best. With dry ice all you have to do is let it dry out from the moisture it acquires when coming to room temperature from being so cold. Just an hour or so and then you can press it. The results are Live Rosin. You get everything from the trichomes that was there at harvest.
I haven't watched the Video, but I assume that's what you're talking about.
