Professional Cameras • Bigger! • More expensive • Interchangeable parts – • Lens • Record deck • Peripherals
Professional Cameras • Professional tape formats • BetaSP • DVPro, DVCam • D1, D2 • Usually component signal
Prosumer Cameras • Mid-range image resolution • Typically in the 400-500 lines range • May have interchangeable parts
Prosumer Cameras • Smaller size • Less expensive than professional • Usually single chip imaging
Prosumer Cameras • Tape formats • MiniDV • Digital 8 & Hi8 • SVHS • Usually component signal
Consumer Cameras • Somewhat low resolution- • Typically less than 300 lines • Single chip image • Very inexpensive
Consumer Cameras • Formats • VHS • Standard 8mm • VHS-C • Composite signal
Signal Types to Tape • Composite • Video info saved as “grouped” • Color & brightness together
Signal Types to Tape • Component • Video info split • Color & brightness separate signals

Analog Tape • Tape format often is described by width of tape- • I inch • ¾ inch cassette • 8 mm • ½ inch VHS
Digital Tape • Tape format is described by the signal type- • miniDV • Digital 8** • DVPro • DVCam
Professional Tape • Open Reel • 2 inch • four video heads • 1 inch • helical scan • Cassette • Beta SP • ¾ inch • D1 & D2
Prosumer Tapes • ¾ inch cassette • S-VHS • s format • Hi8 • s format • Digital 8 • miniDV
Consumer Tapes • VHS • composite format • Standard 8mm • composite format • Digital 8 • miniDV
