Video Lighting Basics
Video analysis of sports performance is often the domain of professional athletes and big companies or research institutions. This analysis is done with teams of 3D face video camera and complicated software to ensure high speed and precision. However, there are some basic techniques that can be used by anyone to assess their own performance and get great results using a simple digital video camera and a little understanding of biomechanics human (the mechanics of human movement). The video camera require a small cost (we'll see what makes a good camera in a future publication), but will provide much of the understanding of biomechanics for free on this blog.
Review of video clips can be a great way to provide training information to players, as well as a way to emulate one favorite athletes. Whether you're a professional All-Star high school athlete or warrior weekend, and yourself from a different perspective can help improve performance and / or minimize the chances of injury.
So In this first posting, let's start from the beginning and describe what features make it suitable for sports video clip the analysis of an individual, and you can do to ensure that the movie clips to meet these requirements. Classifieds future will show the different levels of analysis can be performed in appropriate videos, using a range of software available, from free software based on a detailed analysis in 3D.
What makes a good rate of sports?
A good rate of an individual sports shows full range of athletes of motion (ROM) during an action, with the camera so that the angles can be calculated accurately (this is discussed in more detail below). The shooting athlete ROM can be achieved simply zooming or moving the camera at back until all the desired characteristics in the viewer. It is generally recommended to have the camera as close to the athlete as possible and still capture ROM of all, as this will make more use of sensor resolution of the camera. For example, if we were to catch a basketball player to put the ball, we would ensure that our camera can see the complete action of takeoff until the player puts the ball in the net. Our chamber is therefore need to look at the ground in the take off and a little space above the rim of the Network.
Another important factor in obtaining an image large sport is to make sure the camera is stationary. There are some motion capture software that can handle a camera in motion, but for now we suggest the camera is mounted on a tripod and does not move while the video clip is being filmed. This means you must ensure the range of motion (described above) can be captured in this shot.
How can the film images helpful:
House placement
In general, most sports clips you see on television are best suited for the analysis of strategy and teamwork, as they provide an overview of many or all of the competitors and the playing field. However, when it comes to analyzing the performance of an individual or technique, is not only important to focus the camera on the athlete, but the angle that the film must also be taken into account. It is better to use "orthogonal angles, ie the camera is directly in front, behind or next to the athlete. Golf coverage usually does a good job of this, providing photographs of the golfer either "front" or "down-the-line".
Notice how golf video sequences often have the camera level with the player, which is shot at an angle up or down, which means it is possible to precisely calculate some angles, if that is what is desired in the analysis.
Background / contrast
Although the clip above is a beautiful view of Tiger's swing, the material could have been improved so wear clothes that were a different color background. Black clothing with a black background may make it difficult to assess accurately the amount of hip and shoulder rotation – two commonly discussed the characteristics of a golf swing. Not that having a black background is a bad thing, however, on the contrary, if you can manage to film your athlete with a solid color background, is well on its way to film some scenes in Nice for analysis.
Lighting
As is true with taking more photos, is ideal for camera position and the athlete so that the light source (eg the sun) is behind the camera and illuminates the athlete. This will provide a sportsman's sharp vision, and allow you to use a more open about the opening of the camera.
Now that you are aware of the basics of video footage ideal for analysis, Grab your video camera and start practicing!
