video will not always exactly match up in post with the audio. Unless you have an actual guitarist/drummer whomever the video is featuring doing the edit, you can not be sure that that millisecond delay wont be caught by an outside eye. That being said, I think these videos are edited together very well & frankly the slight offset doesn't affect me at all. None of us, or I should say, most of us will not have the luxury of a videographer who is willing to do hours of splicing & effecting for free, time = money. So maybe the audio doesn't perfectly match up, I would be more bummed if this were an actual demo video, but this is more of an advertisement video for Strandberg.
Just look at the dudes hands, if not in the demo videos, then the live one, if not the live one, watch the studio one closely & ensure that nothing is being speed-altered in post...the dude has CHOPS for days, can't fake that.

It's funny when some of the notes (in a continuous sequence) match the hands and some don't. You can't call that bad sync. Also you're just speculating whereas some people here have inside sources. You probably shouldn't speculate, because you are (according to people involved with the band) wrong.
If you dubbed the riffs in that vid with perfect audio, everyone would believe it's a perfect take, even though actually they're kinda sloppy.
