Seeing Face Rotation on 2D Video

WEBVTT

00:00:00.000 --> 00:00:05.000
This golf smart insight is seeing clubface rotation with 2D video.

2
00:00:05.000 --> 00:00:11.600
So I had a member ask, you know, how can you tell if you're rotating the club

3
00:00:11.600 --> 00:00:12.000
closed

4
00:00:12.000 --> 00:00:17.000
or if you're doing it more with the in-plane movement or arm straightening?

5
00:00:17.000 --> 00:00:19.000
Because it is a little bit tricky to see.

6
00:00:19.000 --> 00:00:23.000
So what I'm going to show you here is how you can use down the line video

7
00:00:23.000 --> 00:00:27.000
to identify whether you're doing it more with shaft rotation

8
00:00:27.000 --> 00:00:33.230
or whether you're doing it more with the in-plane club movement or arm straight

9
00:00:33.230 --> 00:00:34.000
ening.

10
00:00:34.000 --> 00:00:38.000
From the down the line camera, the really telling phase is going to be just

11
00:00:38.000 --> 00:00:39.000
below

12
00:00:39.000 --> 00:00:42.000
waist height or just below shaft parallel.

13
00:00:42.000 --> 00:00:47.000
So what you'll tend to see is from here we have to look in 3D space.

14
00:00:47.000 --> 00:00:50.510
So we're going to have to use face on as well as down the line to see what's

15
00:00:50.510 --> 00:00:51.000
going on.

16
00:00:51.000 --> 00:00:57.000
You'll see that there the clubface rotated towards the ball,

17
00:00:57.000 --> 00:01:03.490
but if I did that facing the camera, that is happening more from the in-plane

18
00:01:03.490 --> 00:01:04.000
movement

19
00:01:04.000 --> 00:01:09.380
or more from my arm straightening, whether my wrist or my triceps or elbows or

20
00:01:09.380 --> 00:01:10.000
whatever.

21
00:01:10.000 --> 00:01:16.000
So if you're looking from face on and you see the club going like this

22
00:01:16.000 --> 00:01:19.590
where the hands stay more towards that right side of the body as the club

23
00:01:19.590 --> 00:01:20.000
passes

24
00:01:20.000 --> 00:01:23.500
and you're looking from down the line and it looks like the clubface is

25
00:01:23.500 --> 00:01:24.000
rotating,

26
00:01:24.000 --> 00:01:29.000
you know that that's happening more from the in-plane movement.

27
00:01:29.000 --> 00:01:35.000
If you see that roughly same amount of club rotation through there,

28
00:01:35.000 --> 00:01:41.450
but then from face on you see the grip working more across the body as that's

29
00:01:41.450 --> 00:01:42.000
happening

30
00:01:42.000 --> 00:01:46.000
then you know that it's happening more from that shaft rotation.

31
00:01:46.000 --> 00:01:50.000
So we'll use a we'll look at a few examples so that we can kind of start

32
00:01:50.000 --> 00:01:54.000
training our mind to see what we're trying to look at

33
00:01:54.000 --> 00:01:58.000
and hopefully you'll be able to see the amount of shaft rotation a little bit

34
00:01:58.000 --> 00:01:58.000
easier,

35
00:01:58.000 --> 00:02:02.110
but we're going to look at it during that phase I just showed you as well as

36
00:02:02.110 --> 00:02:03.000
what's happening

37
00:02:03.000 --> 00:02:05.000
just after the golf ball.

38
00:02:05.000 --> 00:02:09.000
When I'm looking at the video, this is the graph that I'm trying to imagine in

39
00:02:09.000 --> 00:02:09.000
my head.

40
00:02:09.000 --> 00:02:14.000
It's called axial velocity and it's looking at the rotational speed of the club

41
00:02:14.000 --> 00:02:14.000
head

42
00:02:14.000 --> 00:02:16.000
compared to the shaft.

43
00:02:16.000 --> 00:02:20.610
So when it goes negative, the clubface is rotating open and when it goes

44
00:02:20.610 --> 00:02:21.000
positive,

45
00:02:21.000 --> 00:02:23.000
it is rotating closed.

46
00:02:23.000 --> 00:02:27.000
So here's a golfer that has more of a gradual closing in the clubface.

47
00:02:27.000 --> 00:02:31.000
You can see that it starts to get positive actually before he changes direction

48
00:02:31.000 --> 00:02:34.000
and just kind of continues on a gradual slope.

49
00:02:34.000 --> 00:02:40.190
We can contrast that with this example would be a golfer who has more of a

50
00:02:40.190 --> 00:02:41.000
rapid closing later

51
00:02:41.000 --> 00:02:44.000
or uses more of the in-plane movement.

52
00:02:44.000 --> 00:02:48.000
So here you can see the club is opening and then as he changes direction,

53
00:02:48.000 --> 00:02:50.000
you can see that it remains opening.

54
00:02:50.000 --> 00:02:55.000
It's still negative until about shaft 45 or so,

55
00:02:55.000 --> 00:02:59.000
or closer to shaft parallel and then you'll see it closes very quickly.

56
00:02:59.000 --> 00:03:02.000
We can also correlate this graph with the straightening of the arm,

57
00:03:02.000 --> 00:03:05.000
but not everyone has access to this graph.

58
00:03:05.000 --> 00:03:10.000
So let's take a look at video and see how we can imagine it in 3D space.

59
00:03:10.000 --> 00:03:13.000
We'll look at a couple different examples of each style.

60
00:03:13.000 --> 00:03:18.000
It takes a little bit of practice getting to be able to see it

61
00:03:18.000 --> 00:03:22.000
and you can't see it as accurately as you would on the graph.

62
00:03:22.000 --> 00:03:24.000
But we just want to see the general pattern.

63
00:03:24.000 --> 00:03:30.000
So what you're looking for is the clubface angle relative to the shaft.

64
00:03:30.000 --> 00:03:36.000
So if I were to move through these frames,

65
00:03:36.000 --> 00:03:41.000
and let's just indicate where the clubhead is.

66
00:03:41.000 --> 00:03:48.000
That gives us just a rough line of travel that the club is going on.

67
00:03:48.000 --> 00:03:54.000
Now you can see up at the top there the club is pointing straight up and down

68
00:03:54.000 --> 00:04:00.130
and then at this point you can see that it is pointing closer to perpendicular

69
00:04:00.130 --> 00:04:01.000
to the swing plane

70
00:04:01.000 --> 00:04:06.000
and then down here you can see that it's pointing more or less at the ball.

71
00:04:06.000 --> 00:04:11.000
But when you're looking at these two you can see the amount of rotation

72
00:04:11.000 --> 00:04:14.000
kind of through this window or through this phase.

73
00:04:14.000 --> 00:04:18.010
Now that you know what you're looking for you can kind of start to see it

74
00:04:18.010 --> 00:04:20.000
actually happen in through there.

75
00:04:20.000 --> 00:04:25.000
You can actually start to see the club rotating around its axis through there.

76
00:04:25.000 --> 00:04:31.000
Now you want to confirm it by looking at the face-on video

77
00:04:31.000 --> 00:04:36.000
and comparing it to the timing of the straightening of that right arm.

78
00:04:36.000 --> 00:04:40.530
So we know that we were looking at the one on the left and we saw that it was

79
00:04:40.530 --> 00:04:42.000
rotating through this phase

80
00:04:42.000 --> 00:04:46.010
and then we'll see that his arm doesn't really straighten while it's going

81
00:04:46.010 --> 00:04:47.000
through that phase

82
00:04:47.000 --> 00:04:51.000
and there's not a lot of club passing the hands.

83
00:04:51.000 --> 00:04:54.460
When we look at a few examples of the club passing the hands we'll see one

84
00:04:54.460 --> 00:04:56.000
other indicator that you can see

85
00:04:56.000 --> 00:05:01.400
from the face-on view that will give you a key or a clue to see if it's more of

86
00:05:01.400 --> 00:05:03.000
the shaft rotation

87
00:05:03.000 --> 00:05:05.000
or in plain shaft movement.

88
00:05:05.000 --> 00:05:09.390
Okay so we want to train ourselves to be able to see it without having to draw

89
00:05:09.390 --> 00:05:10.000
the line

90
00:05:10.000 --> 00:05:14.990
and here we've got, I wanted to use examples with kind of different grip styles

91
00:05:14.990 --> 00:05:15.000
.

92
00:05:15.000 --> 00:05:19.230
So Dustin obviously has a stronger grip and Jordan's probably more neutral even

93
00:05:19.230 --> 00:05:20.000
to the weak side.

94
00:05:20.000 --> 00:05:26.250
You can see up here that the club head and club face is roughly in line with

95
00:05:26.250 --> 00:05:29.000
the direction it's traveling.

96
00:05:29.000 --> 00:05:35.040
And you can see that by the time he gets to here it's now starting to rotate

97
00:05:35.040 --> 00:05:36.000
and point towards the golf ball.

98
00:05:36.000 --> 00:05:40.640
So you can see actually right in through there is where the club face is

99
00:05:40.640 --> 00:05:42.000
starting to rotate

100
00:05:42.000 --> 00:05:45.460
and then you see the effect of it and it really rotates through that phase

101
00:05:45.460 --> 00:05:46.000
there.

102
00:05:46.000 --> 00:05:52.190
Now let's double check from the face-on view and confirm that it is happening

103
00:05:52.190 --> 00:05:56.000
not with the straightening of the arm.

104
00:05:56.000 --> 00:05:58.000
So we can see that through there.

105
00:05:58.000 --> 00:06:03.380
And the other check that you'll be able to see is kind of the width on the way

106
00:06:03.380 --> 00:06:04.000
through.

107
00:06:04.000 --> 00:06:08.540
If you tend to use more of the in-plane shaft movement you won't have shaft

108
00:06:08.540 --> 00:06:09.000
lean.

109
00:06:09.000 --> 00:06:13.780
So this particular clip misses impact but you can tell by the shaft being

110
00:06:13.780 --> 00:06:18.000
pretty vertical out in front of his lead leg

111
00:06:18.000 --> 00:06:23.060
that he had some shaft lean at impact which would be virtually impossible with

112
00:06:23.060 --> 00:06:25.000
just the in-plane movement.

113
00:06:25.000 --> 00:06:31.190
And what you'll tend to see is on the way through you'll tend to see the club

114
00:06:31.190 --> 00:06:32.000
leaving the ground very quickly.

115
00:06:32.000 --> 00:06:37.260
So you won't have a really long kind of wide flat bottom of the swing. You'll

116
00:06:37.260 --> 00:06:41.000
tend to see the club bottom out even before the golf ball

117
00:06:41.000 --> 00:06:44.070
or be more of a picker style with the irons and you'll see the club come up

118
00:06:44.070 --> 00:06:45.000
pretty quickly.

119
00:06:45.000 --> 00:06:50.380
So let's take a look at a couple examples of golfers who don't have as much of

120
00:06:50.380 --> 00:06:52.000
this face rotation.

121
00:06:52.000 --> 00:06:56.010
Before we look at a couple amateur examples I wanted to show a elite level gol

122
00:06:56.010 --> 00:07:00.000
fer who uses more or less of the face rotation model.

123
00:07:00.000 --> 00:07:05.640
So here you can see filmical sin and you have the clear vision of the club up

124
00:07:05.640 --> 00:07:07.000
against his body.

125
00:07:07.000 --> 00:07:11.000
And you can see that through this space now that you know what to look for.

126
00:07:11.000 --> 00:07:17.520
You can see there's not a lot of rotation. It's pretty much close to the same

127
00:07:17.520 --> 00:07:22.000
angle compared to the path of the club through that space.

128
00:07:22.000 --> 00:07:27.530
It closes a little bit but we want to confirm that that's happening more from

129
00:07:27.530 --> 00:07:30.000
the rotation or the arm extension.

130
00:07:30.000 --> 00:07:34.630
We can look at it from the face on view. We saw that it was starting to rotate

131
00:07:34.630 --> 00:07:36.000
kind of around this zone here.

132
00:07:36.000 --> 00:07:41.560
And you'll see that that left arm, his trail arm is straightening through that

133
00:07:41.560 --> 00:07:42.000
face.

134
00:07:42.000 --> 00:07:46.200
Which tends to give a little bit more of this vertical look at impact with that

135
00:07:46.200 --> 00:07:48.000
right arm really straight.

136
00:07:48.000 --> 00:07:53.380
It'll be even clearer when we look at a few amateurs that it's really that

137
00:07:53.380 --> 00:07:58.450
straightening in the arm that causes the majority of the rotation down here at

138
00:07:58.450 --> 00:08:03.000
the bottom and less of an active twisting of the shaft.

139
00:08:03.000 --> 00:08:08.640
Okay two quick examples from down the line. What we'll see over here on the

140
00:08:08.640 --> 00:08:13.000
right can be a little tricky to tell the amount of rotation.

141
00:08:13.000 --> 00:08:17.550
So one good little checkpoint is if you get the club to let's say halfway

142
00:08:17.550 --> 00:08:20.000
between shaft parallel and impact.

143
00:08:20.000 --> 00:08:26.400
Typically golfers who do this will have more of an open club face and it'll be

144
00:08:26.400 --> 00:08:31.000
pointing more out perpendicular to the target line instead of at the golf ball.

145
00:08:31.000 --> 00:08:34.460
Golfers who've had that shaft rotation are getting the arms more in front at

146
00:08:34.460 --> 00:08:39.660
this point and by this position the club will typically be pointing at the golf

147
00:08:39.660 --> 00:08:40.000
ball.

148
00:08:40.000 --> 00:08:44.460
Now unfortunately that's not absolute. Here's a golfer that appears to have

149
00:08:44.460 --> 00:08:46.000
very little rotation.

150
00:08:46.000 --> 00:08:52.460
But you can see that because of the severity of the closed club face you can

151
00:08:52.460 --> 00:08:56.000
see that it's pointing at the golf ball at this time.

152
00:08:56.000 --> 00:09:02.190
So you can confirm it by looking at the position through or the relationship of

153
00:09:02.190 --> 00:09:05.000
the club face through that space.

154
00:09:05.000 --> 00:09:08.070
Remember we saw with Dustin Johnson that even if you have a stronger grip

155
00:09:08.070 --> 00:09:14.340
having a gradual and gentle closing in the club face through shaft rotation

156
00:09:14.340 --> 00:09:18.290
matches preferred body and arm movements for developing a really consistent

157
00:09:18.290 --> 00:09:21.000
impact position and a good flat spot.

158
00:09:21.000 --> 00:09:27.190
So here's a golfer who breaks the rule but is doing more so with the in-plane

159
00:09:27.190 --> 00:09:32.180
movement. Let's take a quick look at the face on so that you can see what's

160
00:09:32.180 --> 00:09:34.000
going on or why that's happening.

161
00:09:34.000 --> 00:09:38.730
So we wanted to confirm with the face on. Remember the golfer on the right

162
00:09:38.730 --> 00:09:42.730
there was having a little bit of face rotation through this face but you can

163
00:09:42.730 --> 00:09:47.030
see that it's corresponding with more the grip releasing here on the right side

164
00:09:47.030 --> 00:09:48.000
of the body.

165
00:09:48.000 --> 00:09:53.770
Same thing over here we didn't see very we saw very little face rotation but we

166
00:09:53.770 --> 00:09:58.000
did see it happening a little bit down at the bottom.

167
00:09:58.000 --> 00:10:03.380
So you'll see that it's pointing more at the target through this straightening

168
00:10:03.380 --> 00:10:08.910
the arm along the right side of the body and that'll typically cause the club

169
00:10:08.910 --> 00:10:11.000
to come up very quickly.

170
00:10:11.000 --> 00:10:15.980
Same thing over here more along the right side of the body and so the club

171
00:10:15.980 --> 00:10:20.660
tends to come up quickly. You'll often see it accompanied with a chicken wing

172
00:10:20.660 --> 00:10:22.000
or bending in the arms.

173
00:10:22.000 --> 00:10:26.630
So hopefully that helps you understand what it's like to try and visualize this

174
00:10:26.630 --> 00:10:31.150
axial rotation or how much you're squaring the club based on club rotation or

175
00:10:31.150 --> 00:10:33.000
in-plane shaft movement.
