Unlike baseline DV, DVCPRO uses locked audio, meaning the audio sample clock runs in sync with the video sample clock. [14] Audio is available in 16-bit/48 kHz ...
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.
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.
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 ...

DVCPRO (1995): Panasonic released its own variant of the DV format for broadcast news-gathering. DVCAM (1996): Sony's answer to the DVCPRO; DVD recordable (1996): A variety of recordable optical disc standards were released by multiple manufacturers during the 1990s and 2000s, of which DVD-RAM was the first.
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.
Digital8 machines run tape at 29 mm per second, faster than baseline DV (19 mm/s) and comparable to professional DV formats like DVCAM (28 mm/s) and DVCPRO (34 mm/s). A 120-minute 8-mm cassette holds 106 m of tape and can store 60 minutes of digital video. A standard DVCPRO cassette holds 137 m of tape, good for 66 minutes of video.
