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 tracking shot is a blanket term used to refer to any camera shot with movement, with "trucking shot" and "dolly shot" being tracking shot variations. Generally, a "dolly shot" refers to a specific variation of tracking shot in which the camera moves forwards or backwards with respect to the subject.
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 .
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 ...
A camera dolly is a wheeled cart or similar device used in filmmaking and television production to create smooth horizontal camera movements. The camera is mounted to the dolly and the camera operator and focus puller or camera assistant usually ride on the dolly to push the dolly back and forth.
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 unchained camera technique (entfesselte Kamera in German) was an innovation by cinematographer Karl Freund that allowed for filmmakers to get shots from cameras in motion enabling them to use pan shots, tracking shots, tilts, crane shots, etc. [1]
