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.
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 ...
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 ...
Traditionally tracking shots are filmed while the camera is mounted on a track dolly and rolled on dedicated tracks comparable to railroad tracks, In recent years, however, parallel camera moves performed with a Steadicam, gimbal, etc. may also be called a tracking shot. Tracking shots often "follow" a subject while it is in motion: for ...
Also one-shot cinema, one-take film, single-take film, continuous-shot film, or oner. A feature-length motion picture filmed in one long, uninterrupted take by a single camera, or edited in such a way as to give the impression that it was. opening credits (for a film) opening shot (for a scene) over cranking over the shoulder shot (OTS)
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]
the dolly shot, also known as a tracking or trolley shot, in which the camera moves toward or away from its subject while filming. Traditionally dolly shots are filmed from a camera dolly but the same motion may also be performed with a Steadicam or gimbal. A dolly shot is generally described in terms of "dollying in" or "dollying out".
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.
