Motion Capture is most widely used in entertainment, sports, medical applications and computer vision validation. In some fields, it is referred to as motion tracking, but in games and filmmaking, it is called matchmaking. There are many advantages and disadvantages of motion capture.

1. It gives immediate and real time results.
2. It reduces the overall cost of key frame-based animation in the entertainment industry.
5. It is capable of recreating complex movement and realistic physical interactions in a physically accurate manner.
6. The amount of animation data that can be produced within a given time is very large when compared to traditional animation techniques.
7. It can be used with a third party and free software, which makes it cost effective.
1. It requires particular hardware and special software program to produce and process data.
2. The cost of software, equipment and personnel required can potentially be prohibitive for the small productions.
3. The capture system may have particular requirements for the space it is operated in, depending on the camera field of view or magnetic distortion.
4. When problems occur, it is easier to reshoot the scene rather than trying to manipulate the data.
5. The first results are limited to what can be performed within the capture volume without the extra editing of data.
6. The movement that does not follow the laws of physics cannot be captured.
7. Traditional animation techniques, such as the added emphasis on anticipation and follow through, secondary motion or manipulating the shape of a character, as with squash and stretch animation techniques (12 Principle of Animation).
8. If the computer model has the different proportions from the captured subject, artifacts may occur.
