You can be sure those are dry when done. Some do the periodic straightening while the shafts are drying, but I doubt any arrow smith will send out green shafts as done. If he does, I bet he doesn't get a lot of repeat business.
There's a lot of editing done with these informational videos because I doubt you want to watch a guy straighten an arrow over and over for a half hour, then come back and straighten it several more times. A lot of those "straight" arrows that are set aside aren't really done yet, just straight enough for now. We all do plenty of final straightening, don't we?
