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 ...
In the case of VHS, a linear control track at the tape's lower edge holds pulses that mark the beginning of every frame of video; these are used to fine-tune the tape speed during playback and to get the rotating heads exactly on their helical tracks rather than having them end up somewhere between two adjacent tracks. However, the exact ...
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 .
It also allowed multiple DA-88 devices to be combined to record 16 or more tracks. [3] The first models in the series (the TASCAM DA-88, DA-38, DA-98 and Sony PCM-800) recorded at 16-bit resolution. TASCAM later introduced the DA-98HR and DA-78HR, which recorded at 24-bit resolution and sample rates up to 48 kHz (for DA-78HR) and 192 kHz (for ...
