  3. Classifications • Professional • Pro-sumer • Consumer

  4. Professional Cameras • Higher resolution images • Typically in the 600-700 lines range • Usually a 3-chip imaging device • Interchangeable parts

  5. Professional Cameras • Bigger! • More expensive • Interchangeable parts – • Lens • Record deck • Peripherals

  6. Professional Cameras • Professional tape formats • BetaSP • DVPro, DVCam • D1, D2 • Usually component signal

  7. Prosumer Cameras • Mid-range image resolution • Typically in the 400-500 lines range • May have interchangeable parts

  8. Prosumer Cameras • Smaller size • Less expensive than professional • Usually single chip imaging

  9. Prosumer Cameras • Tape formats • MiniDV • Digital 8 & Hi8 • SVHS • Usually component signal

  10. Consumer Cameras • Somewhat low resolution- • Typically less than 300 lines • Single chip image • Very inexpensive

  11. Consumer Cameras • Formats • VHS • Standard 8mm • VHS-C • Composite signal

  12. Signal Types to Tape • Composite • Video info saved as “grouped” • Color & brightness together

  13. Signal Types to Tape • Component • Video info split • Color & brightness separate signals

  14. Signal Types to Tape • Digital • Use transfer protocol • Current is IEEE 1394

  15. Videotape Physical Attributes 2 Basic Types: Open Reel Cassette

  16. Analog Tape • Tape format often is described by width of tape- • I inch • ¾ inch cassette • 8 mm • ½ inch VHS

  17. Digital Tape • Tape format is described by the signal type- • miniDV • Digital 8** • DVPro • DVCam

  18. Professional Tape • Open Reel • 2 inch • four video heads • 1 inch • helical scan • Cassette • Beta SP • ¾ inch • D1 & D2

  19. Prosumer Tapes • ¾ inch cassette • S-VHS • s format • Hi8 • s format • Digital 8 • miniDV

  20. Consumer Tapes • VHS • composite format • Standard 8mm • composite format • Digital 8 • miniDV

  21. Digital Editing Systems & Software Professional “Turnkey Systems” • Includes all hardware, software and peripherals • Avid System • Media 100 • MAC-based

  22. Digital Editing Systems & Software Prosumer • More specialized cards for video • Desktop computer orientation • Software such as Adobe Premiere or Final Cut Pro
