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 ...
The camera dolly may be used as a shooting platform on any surface but is often raised onto a track, to create smooth movement on a horizontal axis known as a tracking shot. Additionally, most professional film studio dollies have a hydraulic jib arm that raises or lowers the camera on the vertical axis.
In production or post-production, reframing can be used to change a sequence without having to reshoot. For example, zooming in on an actor to edit out nudity for a movie to be broadcast over the air. Types of reframing can include: pan, tilt, zoom, crane or boom shot, dolly or trucking shot, handheld shot, tracking shot, and steadycam shot. [1]
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.
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.
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.
There are two methods by which motion information can be extracted from an image. Interactive tracking, sometimes referred to as "supervised tracking", relies on the user to follow features through a scene. Automatic tracking relies on computer algorithms to identify and track features through a shot. The tracked points movements are then used ...
