1. 1 Cameras,Videotape & Formats

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

3. 3 Classifications Professional Pro-sumer Consumer

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

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

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

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

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

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

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

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

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

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

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

15. 15 Videotape Physical Attributes 2 Basic Types: Open ReelCassette

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

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

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

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

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

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

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

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

24. 24 Tripods Strong enough to hold weight of camera Stable Fluid head

25. 25 Tripods The least stable tripod!!

26. 26 Acquisition Decisions Needs of the project Funding User skills Trends
