- A tripod or other methods of keeping your camera steady when capturing videos.
- A digital video camera, however, you can also use a digital still camera, which can shoot in the movie mode.
- Specialized devices and software programs to deliver a ready-made movie from the camera to your PC.
- A meter stick or anything else capable of providing scale.
- A projectile (here, you can actually use a ball or any other similar object).
- Video editing software products, such as |QuickTime Pro or iMovie.
Now you should use your Logger Pro to emulate the motion of the projectile in several dimensions. Using corresponding tabs and tools of the program you can set the desired position of the object, the way it moves and observe the expected result in both Y and X positions.
Then, you can shoot a nice movie, depicting a projectile traveling in space. For this purpose, you’d better use a plain background to get sufficient contract with your projectile. Don’t underestimate the importance of lighting!
Your digital camera should be installed on a tripod. Make sure the plane of motion is set perpendicular to the view.
Properly position the camera, so you could avoid unwanted parallax and scaling problems. Utilize the zoom option for filling the screen with the motion.
The object chosen for scaling should be in the same plane as the motion of your projectile.
Once, the movie is shot, make use of directions, which accompany your camera to transfer the ready-made clip to your PC. If you’ve made more vide than you actually require, make a more manageable length using video editing software such as iMovie or QuickTime Pro. The ready-made clip can be used for your analysis.
