MotionCoach can do standard Side by Side comparison, and better then side by side systems.

With MotionCoach a new concept of Templates have been added to the system. With Templates you only draw the lines once, after that the Template is just reused with any video.

Side by Side comparison is a perfect application for Templates. In the case below MotionCAD is showing two synchronized videos with overlaid lines, with floating video position control.

Video shoot set up:	Position the camera to give you a down the line view ideally the center of the camera view should be in line with the head of the golfer when in the set position.
Processing tool required:	None
MotionCAD required:	Yes
MotionCAD procedure:	When the student video is captured,  simply choose an analysis template from the list, this operation will open the video inMotionCAD with all the lines ready to go. Move the video positions so that both videos are at the same position then lock the two videos together. Now both videos will be synchronized. If you want additional lines and voices over can be created to finish the lesson. Best of all as shown above and below you can draw a single line object over both videos. >

Technique Extension An addition to the technique is to place the videos above and below each other. This is great for making a comparison with weight transfer.

Swing plane is one of the basic analysis techniques, which enhanced by computer and video technology. To perform this analysis place the camera in a “down the line” position ideally between the person’s body and the ball.

Open the captured video in MotionCAD and draw the triangle shown below with the multi-line tool. Next, draw a rectangle around the head. These lines should be done at the set position before any swing movement has been started. This will help monitor problems in the back and down swing.

The resulting video is used to follow the path of the club as the person accelerates it towards the ball. The rectangle around the student’s head helps to monitor body movement through the swing.

This technique works well to show people common “over the top” swings where the club travels high in this swing plane forcing an across the ball impact.

Blended (pro overlay) videos are not required for this analysis, but the overlay adds a great deal of information for the student on how to make correction to their swing.

To calculate the launch angle (Angle ball leaves club) place the camera low next to the ball. In the video picture ensure you have about 2 meters (8 feet) in front of the ball to catch at least one frame of the ball in-flight.

Launch angle is easy to calculate requiring no additional engines or special processing of the video. When capturing video for this purpose it may be useful to slow the exposure rate so that club and ball leave blur tails making measurement easier.

When the video is captured open it in MotionCAD . Draw a circle around the ball before it has been hit, then move the video one frame after the ball has been struck. Draw a line between the ball in flight and before impact. The angle of the line is the launch angle, the line tool has a property that gives the angle of the line, to view this information open the Object Property window by right mouse or double clicking on the line.

A fast and simple video effect that really shocks people. In this analysis you take a detailed look at the differences on a person’s swing at address and impact. Ideally, these two positions should be close to the same (down the line view).

Here we want to show the student problems with weight transfer. Correct weight transfer is critical to swing development. In this case, we would use just a captured video of the student.

Draw a couple of lines to identify where the body is at the set position. These lines provide a reference to judge the body position during the swing. Drawing another line across the hips helps to monitor any straightening of the spine during the down swing.

The freeze frame engine is an ideal video effect engine for this type of visualization.

This is a fast a simple technique that gives the student a very visual key to what is happening with their spine angle during the swing.

Maintaining constant spine angle is critical to building a consistent swing where ball impact is predictable. 

Video shoot set up:	Position the camera to give you a down the line view ideally the center of the camera view should be in line with the head of the golfer when in the set position.
Processing tool required:	None
MotionCAD required:	Yes
MotionCAD procedure:	When the video is captured open the video is MotionCAD. Move the video position to just before the backswing, then use the freehand drawing tool to draw a line from the neck to the base of the back following the contour of the back. This can be seen in the upper video frame.  Now advance the video through the swing, what should occur is that the golfer spine angle should not change through the swing, but in many cases the golfer stands up straighter during through the ball impact. With this technique you should also be able to tell where in their swing the spine angle begins to drift, helping with corrective coaching.

  As shown in the picture, this is a typical example of the visual feedback the golfer can receive through this technique. One of the best points of this technique is that it doesn't matter what type of back the golfer has, the line is customized to the golfer's body.  Technique Extension
An addition to the technique is to make a copy the video or take a picture of the golfer at the set position with the spine line on them for their reference. This provides a more clear picture of where they started and how they ended up.

One of the most important analysis capabilities of the MotionCoach system is to enable self-comparison. With this, you compare yourself at different periods of your swing development.

Because improving a golf swing is an evolution (not a revolution) the importance of self-comparison is two fold: first it provides a historical reference for the golfer, allowing the golfer to monitor swing development over extended periods; Second it keeps the golfer from returning to bad habits that have been changed with lessons.

As an instructor, you do this with repeating customers. In this scenario you would video a person at either the start of a lesson group, or the end. Several weeks later again video the student (could offer as free promotion) and then compare the swings to ensure the lessons are having the desired impact.

As a player you would video yourself to capture your swing when things are working well, possibly at the end of a session. Then when your have problems with your swing you have a reference to return to for comparison.

For these initial videos, you will need to video a background to create the blue screened video . The simplest way to create this video is to set up the camera on a tripod and have the golfer walk into the video and then swing. That way lighting and background are a close as possible to the part of the video with the motion. The extraction video-processing engine allows the background and the process video to be the same.

The most overall and complete of the analysis techniques of the MotionCoach product. With this technique, the model (or goal) swing is slightly overlapped with the student golfer and is made semi-transparent .

In this case, the student reviews the swing in slow motion or frame-by-frame. This provides tempo and motion development feedback all at the same time. The student visualizes their own motion but clearly sees the differences between themselves and the goal motion.

This visualization reinforces the changes recommended by the instructor and accelerates the reprogramming of “muscle memory”.

 Self Monitoring

As used in many schools, mirrors are great for providing instant feedback to the golfer. This is particularly useful when practicing a corrective movement.

MotionCoach can be used to replace the mirror and even enhance this by providing down the line angles not possible with mirrors. To use MotionCoach as a mirror, simply setup the computer monitor close to student so they can see the screen.

To set this up, open MotionCAD and place one or more live video objects on the screen.

Lines can be even superimposed on the live video to give the golfer instant feedback through a virtual framework.
