Video analysis gives professionals and amateurs alike a chance to evaluate a performance or instance in time repeatedly. Video analysis can be found primarily in sports. In some sports, video analysis is used to help the officials make calls on plays. There are many other instances where video analysis helps the situation as well.
Benefits of Video Analysis in Sports
High school, college and professional sports teams routinely video record their practices and games. Sports teams will consult the videos to provide insights into the techniques of the team as a whole and individual players. Having the outside eye of a camera, that is recording a team practicing plays and tactics, helps display where something went wrong in a situation or where something was a success.
Sport analysing companies, that are contracted by teams, can take data from the videos, compile them and give them to the athletes, coaches and trainers.
Practice and athlete training can be slowed down, sped up or enhanced by using computer technology and editing systems. Video analysis also gives coaches and athletes the opportunity to have real-time playback on sports technique, enabling them to monitor changes in technique throughout seasons, careers or lifetimes. Thanks to video analysis, it is also possible to compare technique against world-record breakers and the sport's elite.
Video analysis in sports gives athletes and coaches an opportunity to research, diagnose and compile visual data that can be dissected, moment by moment, which is otherwise unavailable after a moment has passed.
Benefits of Video Analysis in the Arts
Video analysis offers live performers an opportunity not often given often to live actors: self-diagnosed character analysis. More often than not, only the director can see a performance or rehearsal and gauge the work of the actor. The actor's ego needs self-satisfaction though, and the actor will need the assurance that she approves of her own performance, on occasion. During rehearsal, it is helpful to tape the actors performing an entire run-through of the play. This is helpful in revealing unconscious habits the performer has adopted through repetition; which, when left untreated, could lead to glib or unrealistic performances. Taping a rehearsal performance can also bring to the attention of an actor is he is "pushing" or "over-acting"; which on occasion, the actor and director are unaware of.
The same thing is true in dance. These live performers strive to perfect themselves and their techniques, just like athletes. Dance, especially classical dance forms like ballet, require a precision of movement. Muscle memory plays such an important role in performing and sports, that if an untrained movement is ingrained into muscle memory, it will be a hard task to rid yourself of. Analysing videos of practice and rehearsal helps prevent those amateur mistakes from becoming chronic mistakes, by catching them before they are ingrained in muscle memory. Teachers can't see every undisciplined movement or position and video analysis helps a dancer evaluate herself and work on their craft outside of the classroom. Self-evaluation through video analysis is a powerful tool for those who perform for a living.
Benefits of Video Analysis in Security
There are some misconceptions about security video analysis that have been perpetuated by the spy-cam crime shows and films of the early 21st century. The truth is, security video analysis is very much in its infancy, but it is efficient in some regards. Security cameras are good for motion detection, number plate recognition, congestion detection and motion detection. Security cameras help personnel in the detection of theft or trespassing. It is difficult to discern who the person is committing the crime, but crime detection can lead to crime prevention. Real-time video analysis aids security personnel witness and try to prevent crimes from taking place.
In high risk accident areas, local governments have been installing cameras to track people who break the law at intersections. At some intersections, if you run a red light, a motion detecting camera will take a picture of the driver and the number plate. The lawbreaker will then receive a ticket in the mail with a fine equivalent to the severity of the crime. Since the Twin Tower attacks on September 11, 2001 in New York City, most metropolitan areas have installed full surveillance in high risk areas for crime or terrorism. This idea expands on the surveillance available in department stores and malls, but expands the scope of it to intersections and blocks of city environment.
Benefits of Video Analysis in Medicine
Medical personnel also benefit from video analysis, much like how sport trainers benefit from it. Professionals in the medical field, specifically the physical training and rehabilitation field, use video playback to examine and study an injury to better diagnose it. Physical trainers can also compare and contrast healthy movement versus injured movement to try to guide the injured patient back to health. Slowing down a video of someone under physiotherapy can pinpoint areas that still need rehabilitation or improper form in movement that may evolve into another problem.
Video analysis in medicine also proves useful in teaching young surgeons. With the patient's permission, medical employees will record the surgery for academic purposes. In a classroom setting, medical students can watch professional surgeons and through taking notes on what they saw, they can imitate and learn from seasoned professional surgeons. Recording medical procedures are also good for archiving the procedures for future use by students to research the videos or for use by professionals to hone their surgical skills by imitating the surgery secure proper muscle memory. Muscle memory is very important to surgeons who rely on a steady hand to perform the necessary surgery without harming the person undergoing it.
