DVCPRO HD, also known as DVCPRO100 and D-12, is a high-definition video format that can be thought of as four DV codecs that work in parallel. Video data rate depends on frame rate and can be as low as 40 Mbit/s for 24 frame/s mode and as high as 100 Mbit/s for 50/60 frame/s modes. Like DVCPRO50, DVCPRO HD employs 4:2:2 color sampling.
A handheld or Steadicam mounted camera following a similar trajectory is called a tracking shot as well. In fact a tracking shot can use any manual or motorized conveyance, and may include careful planning for passing the camera between vehicles or modes. While the core idea is that the camera moves parallel to its subject, a tracking shot may ...
However, the purpose of a tracking matte is to prevent tracking algorithms from using unreliable, irrelevant, or non-rigid tracking points. For example, in a scene where an actor walks in front of a background, the tracking artist will want to use only the background to track the camera through the scene, knowing that motion of the actor will ...
Video tracking is the process of locating a moving object (or multiple objects) over time using a camera. It has a variety of uses, some of which are: human-computer interaction, security and surveillance, video communication and compression , augmented reality , traffic control, medical imaging [ 1 ] and video editing .
1D (point to point) cable cam system for live TV broadcast of sports and events - Defy Dactylcam and Newton stabilized camera head. A cable-suspended camera system is a system of cables above or along an area to be filmed or videoed, over or along which an attached camera head travels to achieve required camera angles.
Developed to address the needs of the growing number of compressed video standards (DV, DVCPRO, BetaSX, MPEG2) it allows lossless transfer of data to other devices which have the same codec, for example DV to DV or SX to SX.
Often the camera is mounted on a camera dolly which rides on rails similar to a railroad track; in this case, the shot is referred to as a dolly shot." Note that in one sentence tracking shots are said to be different from dolly shots, and in the next a tracking shot can be referred to as a dolly shot. This article needs a thorough revision.
Follow shot is a specific camera angle in which the subject being filmed is seemingly pursued by the camera, for example by a Steadicam.The follow shot can be achieved through tracking devices, panning, the use of a crane, and zoom lenses resulting in different qualitative images but, nevertheless, recording a subject (performer) in motion.
