## Title
Method of providing specialized dance videos

## Abstract

A musical video is made at a first time of a dancer whose head is stationary but whose feet and body are moving in synchronism with a dance song. The dancer's head is then removed from the video. At a festive occasion (e.g., a birthday party) at a subsequent time, the dance song is replayed and a video is made of the response of the head, in a stationary position, of one or more of the celebrants at the festive occasion to the dance song. The celebrant's head is combined with the dancer's body to produce two (2) videos are then combined into a single video in which the celebrant's head appears on the dancer's body.

## Background
This invention relates to systems for, and methods of, producing specialized musical videos. The invention particularly relates to systems for, and methods of, producing specialized musical videos in which the specialized musical videos are produced at festive occasions to enliven the activities at the festive occasions.
BACKGROUND OF THE INVENTION
At festive occasions such as at birthday parties, baptisms and bar mitzvahs, there is always a need, or at least a desire, to have the celebrants participate in activities which will impart a joyous atmosphere to the occasion. For example, a master of ceremonies and a dance band are often provided to enliven the celebration. However, attempts are constantly being made to enliven the activities in new ways that have not previously been tried.
BRIEF DESCRIPTION OF A PREFERRED EMBODIMENT OF THE INVENTION
A musical video is made at a first time of a dancer whose head is stationary but whose feet and body are moving in synchronism with a dance song. The dancer's head is then removed from the video. At a festive occasion (e.g., a birthday party) at a subsequent time, the dance song is replayed and a video is made of the response of the head, in a stationary position, of one or more of the celebrants at the festive occasion to the dance song. The celebrant's head is combined with the dancer's body to produce two (2) videos are then combined into a single video in which the celebrant's head appears on the dancer's body.



BRIEF DESCRIPTION OF THE DRAWINGS
In the drawings:
FIG. 1 is a schematic perspective view of an individual dancing with the individual's head in a stationary position and further indicates schematically a camera for producing a video of the movements of the dancer's body and feet in synchronism with the dance music and the removal of the dancer's head from the video; and
FIG. 2 is a schematic perspective view of a celebrant, or celebrants, at a festive occasion and illustrates how a video is taken of the dancers moving in synchronism with the dance music but with the celebrant's head replacing the dancer's head in the video.



DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT OF THE INVENTION
In one embodiment of the invention, a fixture generally indicated at 10 in FIG. 1 is provided. The fixture includes a pair of spaced stanchions 14 and 16 for supporting a crossbar 18. A support 20 extends from the crossbar 18 in a direction transverse (preferably perpendicular) to the crossbar for holding a helmet 22. The helmet 22 is disposed on the head 24 of a dancer 26 in a substantially fixed and stationary position. However, the dancer's body and feet are capable of moving subject to the constraint imposed on the dancer's head by the helmet 22. Any number of dancers can be provided, each constrained in the manner shown in FIG. 1 and described above.
An audio reproducer 28 is provided for producing a dance song and the dancer 26 dances in response to the dance song. A movie camera 30 records in a video medium (e.g., a tape) the audio of the dance song and the dancer's physical response to the dance song. Another video is then provided in which the dancer's head is removed from the secondary as at 32. Alternatively, the camera 30 can record the image of the dancer's body but not the dancer's head.
At a subsequent time such as at a festive occasion, celebrants 34 sit in a foreground enclosure 36 in FIG. 2 with their bodies within the enclosure but with their heads exposed. The enclosure 36 may have a particular color such as green. Cut-outs 38 nay be provided in the foreground enclosure 36 in which the necks of the celebrants 34 may be disposed. The cut-outs 38 limit the lateral, longitudinal and vertical movements of the celebrants' heads. A background 40 may be disposed in back of the enclosure 36 and may also be provided with the particular color such as green.
The video previously recorded by the camera 30 in FIG. 1 is then replayed to the celebrants 34 or by a video replayer 42 so that the heads of the celebrants can respond to the music. The video replayer 42 is connected to a camera 44 to introduce the video recording in the replayer 42 to the camera 44. The camera 44 records the response of the heads of the celebrants 34 to the music in synchronism with the dance music and in synchronism with the movements of the body and legs of the dancers 26. In this way, the heads of the celebrants 34 became disposed on the bodies of the dancers 26, in place of the dancer's heads, so that the movements of the celebrants' head and the dancers' bodies are in synchronism with the dance music.
The camera 44 may be disposed closer to the celebrants 34 than the distance between the cameras 30 relative to the dancers 26. This tends to enlarge the heads of the celebrants 34 relative to the bodies and legs of the dancers 26. This enlargement is provided so that the heads of the celebrants 34 will always be disposed on the necks of the dancers 26 in the video recorded in the camera 44. A digital computer 45 may be provided to adjust for changes in the position of the dancer's body, thereby to align the dancer's body with the celebrant's head.
The camera 44 is provided with chromakey apparatus 46. The chromakey apparatus 46 eliminates the green color from the foreground enclosure 36 and the background 40 in the video being recorded in the camera 44. A different background may be recorded in the camera 44 in substitution for the green background 40. The resultant video recorded in the camera 44 may be provided as a gift to the celebrants 34 as a memento of the good time that they had at the festive occasion.
Although this invention has been disclosed and illustrated with reference to particular preferred embodiments, the principles involved are susceptible for use in numerous other embodiments which will be apparent to persons of ordinary skill in the art. The invention is, therefore, to be limited only as indicated by the scope of the appended claims.
