1 Cameras,Videotape & Formats

2 Objectives Describe three classifications of video equipment Describe camera classifications Identify the types of videotape and videotape formats Discuss acquisition strategies

3 Classifications Professional Pro-sumer Consumer

4 Professional Cameras Higher resolution images –Typically in the 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 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 ReelCassette

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

23 Digital Editing Systems & Software Consumer Simple IEEE 1394 cards Desktop computer orientation Software such as Avid Cinema, Videowave, iMovie
