Good video, should help alot of people. It got me thirsty for a diet dew...not sure why

Succinct! Thanks Brian.

Great a stuff as always, loved the imagination with the props. Diet dew is soooooo good, but not as good as being top 100 and surely not as good as #1.

Could we make a reasonable assumption that teaching a new golfer ball position and alignment prior to developing their very own personalized swing pattern could be counter-productive?
IMO, nearly every golfer that plays the game imagines that they are aligning themselves to some particular target (although their setup and ball position may not allow it to happen) then develop horrible habits trying to correct themselves. It's the birthplace of the flip.

I Like the improvising with things in the room!
Just like during your lessons when you use props that are just there at the time.
When you truly understand the concepts you can get your point across with things around you at the time.
Great video!

I see that but it would seem to me that the club path shortly before impact and shortly after impact is all that is important as far as curvature of the ball. You could have the same general swing path (from beginning to end) and have the last ball curve further left if you're still hitting the ball "inside out" (the ball has no idea what's your intended target line). You could also hit the ball "outside in" as you say but that depends on precisely your path shortly before impact and shortly after impact and would not seem to matter where in the stance you put the ball. Based on Brian's demonstration I think the ball could have been hit "inside out" or "outside in" relative to tangential swing path vector at the moment of impact. Also why is it not "inside out" or "outside in" relative to the D plane?

The last ball definitely has an "inside out" path, but the face is at the camera so it goes basically that direction (at camera) initially and curves away from the path. Watch the D Plane basics video on the homepage.
Also, if not sure about face versus path influence, check out the chart on this page:

Not sure your question, but Brian was demonstrating that the ball would have 3 major different flights with the same swing depending on ball position. You are right that the resultant path is different at each impact. For any of those three impacts, the resultant (or net) path is the bottom vector of the dplane.

I think I understand why the ball would start left of the intended target line (from Brian's perspective) but not sure why the ball would slice (I'm mainly trying to understand how the curvature of the ball flight is determined). It seems to me that his swing could still be "inside out" relative to the tangential swing path vector in which case the ball would start left and hook further left. The only way the ball would start left and curve right is if the club face is closed relative to the target line and the swing is "outside in" relative to the tangential swing path vector (or another relevant vector).

The way I understood it was that the third ball was too far forward and the first ball (farthest from the camera) was too far backward and the face is square to the target at impact. For the ball closest to the camera (third ball), that is equivalent to a very outside-in swing with the face laying back but square to the target (this would also put the club head more toe-up at impact). The toe-up club head would effectively point the face left of the target but it would slice right because of the left-to-right spin and go higher due to the club face laying back and adding loft.
Noobie, in general terms, the ball starts where the face is looking and curves away from the path (if the path is not the same direction as the face). I think you will need to review more of the dplane videos and writeups to start grasping that.
I would also say I think you are over-analyzing with all those inside out, tangential,and target line references. Just think moment of impact. Nothing else before or after really matters.

The toe up club head explanation makes sense to me although I would think that in a swing such as the one Brian describes (where first ball has a hook spin and the second ball has pretty much a straight ball flight), club head would be in a toe down position after the third ball. That's why I was asking about Brian's finish in which he looks like he's purposely holding the club face up.
Yeah I will review the videos when I get home tonight. I understand D plane as far as the initial direction of a ball. My questions pertain to the curvature of the ball afterwards. Think of it like this, if you're a fly on top of the club face, it would like you're going left (inside-out) throughout all three ball positions. How does a ball know that someone has swung outside in? The only way is if "inside out" or "outside in" is relative to either the D plane at impact, club head path vector at impact, or some other vector at impact. The mere fact that the club head is going right on our screen after contacting the third ball does not mean that club is in an outside in swing path (imagine if you viewed the exact same swing but you were standing directly left of Brian- the swing at 3rd ball would look similar to impact at the 2nd ball).

I think that is why he said that the vertical plane would be 45 degrees for all three impacts.
Brian showed the 3 dplanes for the three impacts in the video. After impact think that the ball will move up the dplane.
Now...talking from the normal perspective of the golfer....
For the first ball the dplane is tilited lower right to upper left - ball will go ("curve") to the left. For the last ball, the dplane is tilited lower left to upper right - ball will go ("curve") to the right.
