Video Analysis - Distance Control

WEBVTT

1
00:00:00.000 --> 00:00:06.960
All right, golfers, welcome back.

2
00:00:06.960 --> 00:00:11.520
Let's take a look at analyzing your putting video for the purpose of distance

3
00:00:11.520 --> 00:00:12.500
control.

4
00:00:12.500 --> 00:00:15.360
So this will be quick and easy.

5
00:00:15.360 --> 00:00:18.600
There's only a few factors where it comes to the distance control.

6
00:00:18.600 --> 00:00:20.880
Ultimately, it comes down to the speed of the golf ball.

7
00:00:20.880 --> 00:00:25.450
When you hit the golf ball, you're going to launch it at a specific speed, the

8
00:00:25.450 --> 00:00:26.480
ball speed.

9
00:00:26.480 --> 00:00:31.810
Just like when you hit a driver and you're hitting it 180 miles per hour, we

10
00:00:31.810 --> 00:00:32.280
know how

11
00:00:32.280 --> 00:00:35.920
far the ball is going to go given what launch angle and spin.

12
00:00:35.920 --> 00:00:41.210
Well, in this case, the ball speed is going to have a big impact on the

13
00:00:41.210 --> 00:00:41.680
distance.

14
00:00:41.680 --> 00:00:46.970
The main factors for ball speed are going to be the length of the stroke, the

15
00:00:46.970 --> 00:00:47.840
acceleration

16
00:00:47.840 --> 00:00:53.260
rate, and then the quality of hit, as well as the quality of roll, which comes

17
00:00:53.260 --> 00:00:53.880
down to

18
00:00:53.880 --> 00:01:00.600
your putter face to angle the tack relationship.

19
00:01:00.600 --> 00:01:05.010
If you have too much loft or you're hitting down on it, the ball will skid and

20
00:01:05.010 --> 00:01:05.600
that gives

21
00:01:05.600 --> 00:01:07.600
you inconsistent roll.

22
00:01:07.600 --> 00:01:11.860
If you had too much kind of closing, you could potentially get some topspin and

23
00:01:11.860 --> 00:01:12.360
that would

24
00:01:12.360 --> 00:01:14.200
also affect the roll.

25
00:01:14.200 --> 00:01:19.900
So we'll look at how to analyze your ball roll just using your simple phone or

26
00:01:19.900 --> 00:01:20.560
high-speed

27
00:01:20.560 --> 00:01:21.960
video.

28
00:01:21.960 --> 00:01:27.240
But the big factors are going to be a look at training your ability to control

29
00:01:27.240 --> 00:01:27.480
the length

30
00:01:27.480 --> 00:01:32.270
of stroke, training your tempo, and then assessing the quality of your ball

31
00:01:32.270 --> 00:01:32.880
roll.

32
00:01:32.880 --> 00:01:38.170
That's the recipe for understanding why you might have trouble with distance

33
00:01:38.170 --> 00:01:38.720
control.

34
00:01:38.720 --> 00:01:44.470
So simple, we're primarily going to use the face-on keys for looking at length

35
00:01:44.470 --> 00:01:45.360
of backswing

36
00:01:45.360 --> 00:01:50.650
to follow through, as well as I recommend recording the video in regular speed

37
00:01:50.650 --> 00:01:51.120
so that

38
00:01:51.120 --> 00:01:57.020
you can see the overall tempo and see if you have any really fast changes of

39
00:01:57.020 --> 00:01:58.280
acceleration

40
00:01:58.280 --> 00:02:00.300
or if you're kind of slowing it down.

41
00:02:00.300 --> 00:02:06.000
So a lot of golfers who have poor speed control tend to take a similar length

42
00:02:06.000 --> 00:02:07.200
backstroke on

43
00:02:07.200 --> 00:02:11.600
different length putts and then change the acceleration rate to try to either

44
00:02:11.600 --> 00:02:12.040
hit it

45
00:02:12.040 --> 00:02:13.560
harder or softer.

46
00:02:13.560 --> 00:02:20.240
I highly recommend you get your acceleration rate fairly consistent and then

47
00:02:20.240 --> 00:02:20.960
work on being

48
00:02:20.960 --> 00:02:25.640
able to hit different length backstrokes.

49
00:02:25.640 --> 00:02:29.230
Once you have that in place, then the fine-tuning comes when you look at the

50
00:02:29.230 --> 00:02:30.080
quality of the

51
00:02:30.080 --> 00:02:32.280
roll.

52
00:02:32.280 --> 00:02:36.560
To get the quality of the roll, we can look at the golf ball or potentially you

53
00:02:36.560 --> 00:02:37.160
can look

54
00:02:37.160 --> 00:02:41.400
a little bit at some indicators from the face-on view.

55
00:02:41.400 --> 00:02:46.980
You can look at the height of the putter being higher in the finish compared to

56
00:02:46.980 --> 00:02:48.320
before impact.

57
00:02:48.320 --> 00:02:51.470
That's helping making sure that we're hitting up on the ball and then you can

58
00:02:51.470 --> 00:02:51.920
look at the

59
00:02:51.920 --> 00:02:54.480
putter face twisting.

60
00:02:54.480 --> 00:03:00.180
A lot of twisting typically can cause putter loft issues and that loft will

61
00:03:00.180 --> 00:03:00.980
turn into

62
00:03:00.980 --> 00:03:05.280
different rolls or different ball speed.

63
00:03:05.280 --> 00:03:09.410
So that can be a big impact or have a big impact on your ability to control

64
00:03:09.410 --> 00:03:10.280
your speed.

65
00:03:10.280 --> 00:03:19.040
But let's take a look at analyzing the stroke from a more consistency parameter

66
00:03:19.040 --> 00:03:19.400
.

67
00:03:19.400 --> 00:03:24.490
When you're looking at distance control, the two primary things that you want

68
00:03:24.490 --> 00:03:24.880
to look

69
00:03:24.880 --> 00:03:29.480
at are acceleration rates.

70
00:03:29.480 --> 00:03:34.650
With acceleration rates, we're looking for tendencies to hit the ball either

71
00:03:34.650 --> 00:03:34.840
with your

72
00:03:34.840 --> 00:03:40.540
wrist or with your shoulders or with your hips, but we're looking for rapid

73
00:03:40.540 --> 00:03:41.600
accelerations

74
00:03:41.600 --> 00:03:46.160
or slamming on the brakes and having a long stroke and a short finish.

75
00:03:46.160 --> 00:03:52.240
It's a little less common, more golfers struggle with a hit tendency.

76
00:03:52.240 --> 00:03:57.640
Looking at acceleration rates and then looking at stroke length.

77
00:03:57.640 --> 00:04:02.390
Length of backswing compared to length of follow-through, looking for them to

78
00:04:02.390 --> 00:04:03.000
be about

79
00:04:03.000 --> 00:04:04.000
even.

80
00:04:04.000 --> 00:04:07.950
Those are two big stroke patterns that you'll look at from the face-on if

81
00:04:07.950 --> 00:04:09.060
distance control

82
00:04:09.060 --> 00:04:10.720
is your major issue.

83
00:04:10.720 --> 00:04:14.950
When you're analyzing the quality of the roll, we can look at it either from

84
00:04:14.950 --> 00:04:16.080
down the line

85
00:04:16.080 --> 00:04:22.120
where we can see how well the ball is rolling end over end or we can look at it

86
00:04:22.120 --> 00:04:23.040
from a close

87
00:04:23.040 --> 00:04:25.240
up of face-on.

88
00:04:25.240 --> 00:04:28.680
One of the other important things when looking at speed control can be looking

89
00:04:28.680 --> 00:04:29.240
at quality

90
00:04:29.240 --> 00:04:30.520
of roll.

91
00:04:30.520 --> 00:04:35.110
We saw from this view we can get a good sense of the end over end, but if you

92
00:04:35.110 --> 00:04:36.000
're looking

93
00:04:36.000 --> 00:04:40.180
to see if the golf ball is skidding or not, or if it's getting backspin, you

94
00:04:40.180 --> 00:04:40.800
want to look

95
00:04:40.800 --> 00:04:43.440
at it close up from the face-on view.

96
00:04:43.440 --> 00:04:49.200
Now I recommend doing this in your higher speed, so this is 240 frames, but you

97
00:04:49.200 --> 00:04:49.640
can see

98
00:04:49.640 --> 00:04:55.800
even at 240 frames, it's a little bit tricky, it moves pretty quickly there.

99
00:04:55.800 --> 00:05:00.880
Looks like it rolls off the, or starts rolling right away.

100
00:05:00.880 --> 00:05:08.250
If we break it down and we look more frame by frame, you can see there the golf

101
00:05:08.250 --> 00:05:09.000
ball was

102
00:05:09.000 --> 00:05:15.230
in the air and we can even kind of scrub through and look as we hit it, we can

103
00:05:15.230 --> 00:05:16.080
see the line

104
00:05:16.080 --> 00:05:20.360
not changing much and then it's not until right there where the golf ball makes

105
00:05:20.360 --> 00:05:20.900
contact

106
00:05:20.900 --> 00:05:25.090
with the ground that it then starts to roll end over end and you can see not a

107
00:05:25.090 --> 00:05:25.480
lot of

108
00:05:25.480 --> 00:05:28.920
skidding or bouncing.

109
00:05:28.920 --> 00:05:34.210
Often times if you have poor speed control, what you'll see is the line in the

110
00:05:34.210 --> 00:05:34.840
air will

111
00:05:34.840 --> 00:05:38.630
typically be going backwards, so you'll be creating backspin and you'll get a

112
00:05:38.630 --> 00:05:39.120
bounce

113
00:05:39.120 --> 00:05:42.920
when it hits instead of just initial roll when it hits.

114
00:05:42.920 --> 00:05:49.000
So this has a high correlation with distance control.

115
00:05:49.000 --> 00:05:56.160
Now I should point out when you do this very close up view if we look at the

116
00:05:56.160 --> 00:05:59.000
last one here,

117
00:05:59.000 --> 00:06:05.400
what you'll see is if you use the high speed camera from the iPhone, it kind of

118
00:06:05.400 --> 00:06:06.280
provides

119
00:06:06.280 --> 00:06:12.840
a little bit of a warped fish eye look where you see a lot of face rotation.

120
00:06:12.840 --> 00:06:17.140
So you want to cross reference the face rotation you would see with this close

121
00:06:17.140 --> 00:06:17.920
up view with

122
00:06:17.920 --> 00:06:21.880
either the overhead or the down the line to see if that's really an issue

123
00:06:21.880 --> 00:06:22.560
because in

124
00:06:22.560 --> 00:06:23.920
this case it's not.

125
00:06:23.920 --> 00:06:27.800
This is just the best setup for looking at the ball roll.

126
00:06:27.800 --> 00:06:33.090
So when you look at that close up, here's impact or just before impact, there's

127
00:06:33.090 --> 00:06:33.520
a small

128
00:06:33.520 --> 00:06:34.660
gap there.

129
00:06:34.660 --> 00:06:38.290
Just after impact you can see the putter line is still the same and then it's

130
00:06:38.290 --> 00:06:38.920
not until

131
00:06:38.920 --> 00:06:44.090
it gets past my foot when the ball actually lands that it starts to tumble and

132
00:06:44.090 --> 00:06:44.440
roll.

133
00:06:44.440 --> 00:06:50.960
So that's important for having predictable distance control.

134
00:06:50.960 --> 00:06:55.530
If you're getting, especially backspin, if you're getting a little flippy and

135
00:06:55.530 --> 00:06:56.120
adding

136
00:06:56.120 --> 00:06:59.990
loft and getting backspin, the ball will tend to skid and you'll have a lot

137
00:06:59.990 --> 00:07:00.720
harder time

138
00:07:00.720 --> 00:07:04.000
controlling distance control.

139
00:07:04.000 --> 00:07:07.040
But I still put this as kind of like a fine tuning.

140
00:07:07.040 --> 00:07:11.540
The big elephant in the room is looking for how well you can do length of back

141
00:07:11.540 --> 00:07:12.240
swing and

142
00:07:12.240 --> 00:07:14.360
how well you can control your tempo.

143
00:07:14.360 --> 00:07:18.840
If those are off then I really don't care about the quality of the roll.

144
00:07:18.840 --> 00:07:22.710
We want to use training those two scales to get us at least at a better

145
00:07:22.710 --> 00:07:23.880
starting point.

146
00:07:23.880 --> 00:07:27.410
All right, so here's a quick checklist for assessing your ability to control

147
00:07:27.410 --> 00:07:28.080
distance.

148
00:07:28.080 --> 00:07:32.240
I want you to first look at the length of stroke, how well you're able to

149
00:07:32.240 --> 00:07:32.920
control the

150
00:07:32.920 --> 00:07:33.920
length of stroke.

151
00:07:33.920 --> 00:07:38.650
You can hit a couple different putts and see how much longer the putting stroke

152
00:07:38.650 --> 00:07:39.280
gets.

153
00:07:39.280 --> 00:07:43.330
Then looking at tempo, so looking at the acceleration rate, we don't want to

154
00:07:43.330 --> 00:07:44.040
see really

155
00:07:44.040 --> 00:07:48.120
rapid change of direction or decelerating.

156
00:07:48.120 --> 00:07:52.110
You can look from the down the line to see center contact and if those are all

157
00:07:52.110 --> 00:07:52.600
pretty

158
00:07:52.600 --> 00:07:56.640
good and you're still just not quite as clean as you would like, I highly

159
00:07:56.640 --> 00:07:57.920
recommend assessing

160
00:07:57.920 --> 00:08:03.040
your golf ball roll to see if the ball is skidding versus rolling purely.

161
00:08:03.040 --> 00:08:08.330
So if you master that little hierarchy there and you get good at training

162
00:08:08.330 --> 00:08:09.480
length of swing,

163
00:08:09.480 --> 00:08:13.120
training tempo, quality of strike and roll, there's no way you're not going to

164
00:08:13.120 --> 00:08:13.600
be a good

165
00:08:13.600 --> 00:08:14.600
putter.

166
00:08:14.600 --> 00:08:18.860
So this is the recipe I want you to use as you be your own coach for assessing

167
00:08:18.860 --> 00:08:19.220
your

168
00:08:19.220 --> 00:08:21.320
speed control on your stock putting stroke.
