Abstract

A method of producing a video recording so as to facilitate a comparison of the performance of an expert (1) with that of a less accomplished player (2) in a sporting technique such as a golf swing. Two video recordings are made and are then edited together using a split screen method to produce a composite video with the techniques synchronised as appropriate.

Description

PRODUCTION OF VIDEO RECORDINGS
This invention relates to the production of video recordings and in particular to the production on a video tape, disc or any other suitable media of a comparison of two sequences of events. The invention is primarily intended for use in teaching sports or assessing sports abilities.
In most sports, particular techniques need to be developed. Typical examples are a golf swing, a tennis shot, or a cricket shot. It is well known that training for these sports can involve a video recording of a person's technique which can then be assessed, criticised and so forth.
It is also known that people can learn techniques by observing the manner in which successful sportsmen or women carry out the techniques themselves. It is possible to obtain learning courses which consist of lessons on a video recording and include views of techniques being put into practice by an experienced player.
A failing of existing systems is that it is not easy for a person to assess how his or technique differs from the ideal. In a lesson, a person may be shown a video recording of his performance for criticism, and may be shown video recordings of more accomplished players for comparison. However, it is difficult for the person to assess the differences in detail.
According to the present invention, there is provided a method of producing a video recording for use in teaching and/or analysing a sporting technique carried out by a person, comprising the steps of:-
(a) Making a first video recording of a first person carrying out the sporting technique in what is taken as a standard manner;
(b) Subsequently making a second video recording of a second person carrying out the same technique in a manner that is assumed to differ from the standard manner; and
(c) Producing a composite video recording by editing together the first and second video recordings using a split screen method, and synchronising the carrying out of the technique by the first and second persons, whereby the composite recording comprises a series of frames each showing a step in the carrying out of the technique by the experienced person and a corresponding step in the carrying out of the technique by the second person.
Thus, when the recording is played, the frames will show on a television screen the first person alongside the second person, carrying out the technique in synchronism as far as is practicable. This greatly facilitates comparing the performances.
The first and second persons could both be of the same standard but the method of the invention is particularly intended to permit a person to compare his performance in detail with that of a more experienced player and exponent of the technique. Typically the first person will be a successful and well known sportsperson such as a golfer, cricketer, tennis player or the like. In such a case, the first recording could be made well in advance and if desired a number of techniques could be stored. The second person will generally be a member of the public wishing to compare performance with the expert. Naturally, the first recording would be used many times to produce separate composite recordings for 5 as many members of the public who have featured in tf recordings.
Whilst it is conceivable that the method could be carried out using video recordings made by members of the public themselves, for example, this would
10 complicate matters and it might be necessary to keep many different views of the expert so as to correspond to the views that a member of the public might provide. Accuracy would not be guaranteed. Accordingly it is preferred to have a standard camera shot from a
15 particular distance and direction which is under the control of the provider of the composite video recording. This will be used to record the expert and the member of the public. Of course, there could be a number of such standard camera shots depending on the
20 aspects of the technique that it is wished to analyse and compare. Typically, views from two directions would be used.
It may be desirable to have a booth or the like in which the recordings can be made, with video cameras in 25 particular positions, markings for the feet to ensure that the person is in the required standard position relative to the cameras, and so forth. The original recording by the expert can have been made in the same or a similar booth.
30 The making of the two basic video recordings can be by means of conventional video camera and recording equipment. The editing of the two video recordings together can be achieved using standard editing equipment and split screen methods. The synchronisation of the respective techniques of the two players may need to be effected by a system of trial and error to a certain extent. It may not be sufficient to simply have e.g. two golf swings start simultaneously. It may be more appropriate in some cases to choose a reference point in the middle of the swing or at the end. The synchronisation may be such that particular portions of the technique can be compared alongside each other even though they would not be reached at the same time from the start of the swing by the two players. The composite recording could have portions with different forms of synchronisation resulting from different reference points being chosen. In many cases, where a general analysis is required, it will be sufficient to have the reference point chosen for synchronisation during as much of the technique as practicable. In other cases it will be desirable to synchronise particular shorter portions rather than the maximum practicable.
The composite video recording will usually be in the form of a tape cassette or a disc for use with domestic video machines. The composite recording could include portions of fast or slow motion, frozen frames to enable closer analysis and comparison of techniques, a commentary and/or the display of written matter comparing the techniques or just introducing different parts of the recording, arrows highlighting particular points of a person to be studied, advertising material and so forth. The composite recording could include additional sequences of e.g. either person alone.
Naturally, the person playing back the recording will be able to use any controls on his video machine to vary how the recording is displayed. In commercial exploitation of the method, sites could be set up at golf courses during tournaments, in golf professional's shops at courses, in sports stores, at exhibitions and so forth. Members of the public would have their performances of a technique, such as a series of golf swings, recorded. This recording would be despatched to a central editing studio where the composite video recording would be made and sent to the customer.
The accompanying drawing illustrates the appearance of one frame from a video recording made in accordance with the invention. The split screen technique is used to compare the golf swings of an expert (1) and a less experienced and accomplished player (2) , with the two players alongside each other on a television screen which is effectively split into two equal parts. As the video recording is played, there would be shown the cumulative effects of the different techniques of the two players. There could even be provided a shot of the flight of the ball after it is hit, to illustrate the end results of the different techniques.
The invention could be extended to cover the study of other techniques. Whilst the principal purpose of the method is to enable the detailed comparison of sporting techniques such as a golf swing, there will be other areas of application.
Whilst it is anticipated that in most cases the video recordings wil be on e.g. magnetic tapes or optical discs, it would be possible to use cinematographic films and the expression "video recording" is to be so construed where appropriate. Furthermore, for comparison purposes it may be desired to use more than two recordings and to compare three or more players.
