    8. 8. Reel-to-Reel
    9. 9. Cassettes
    10. 10. CDs
    11. 11. iPods
    12. 12. What’s Next?
    13. 13. Celluloid
    14. 14. Video Tapes
    15. 15. DVD
    16. 16. What’s Next?

    23. 23. What’s Next?
    24. 24. The Scenario
    25. 25. What We Know <ul><li>The client wants to go online with their courses. </li></ul><ul><li>The courses are composed of ppts, images, videos, documents, and audio (for our purposes: legacy materials).  </li></ul>
    26. 26. What We Don’t Know <ul><li>These courses may also use older materials, such as video tapes, floppies, microfiche, and photocopies. </li></ul><ul><li>These materials may already be virtual, but we can assume from the nature of the question that a portion are physical. We don't really know. </li></ul><ul><li>They may be synchronous or asynchronous courses and materials, but we don't know. </li></ul>
    27. 27. The Approach <ul><li>The groups doing the most work on conversion from legacy materials to digital materials and their deployment are museums, libraries and universities, and public sector organizations. </li></ul><ul><li>These organizations have already stumbled on benchmarks and constraints (i.e. the size of video files, cost of conversion, cost of storage, etc.) and navigated around problems. </li></ul><ul><li>The move from physical training materials to digital materials is analogous to moving classes online. </li></ul>
    28. 28. Analyzing Needs <ul><li>How do you decide what to digitize and what not to? </li></ul>
    29. 29. It Depends… <ul><li>Depends on your mission and your organization </li></ul><ul><li>Depends on the media </li></ul><ul><li>Depends on your users </li></ul><ul><li>Begin with the End in Mind </li></ul>
    30. 30. Principles to consider <ul><li>Cost </li></ul><ul><li>Use </li></ul><ul><li>Condition of original </li></ul><ul><li>Rescanning in future? </li></ul><ul><li>Type of organization </li></ul><ul><li>Begin with the End in Mind </li></ul><ul><li>Customize and Tailor </li></ul>
    31. 31. Different Materials Different Problems <ul><li>Paper documents are the least complex due to standardized nature and use of content </li></ul><ul><li>Audio is complex due to changing formats. Reformatting may occur less often than video but more often than text </li></ul><ul><li>Video and film are the most complex due to both visual and audio elements, reformatting may be needed often </li></ul>
    32. 32. Cost of Digitization <ul><li>Technology is becoming less expensive </li></ul><ul><li>Cost of storing digital materials </li></ul><ul><li>Cost of storing analog materials </li></ul><ul><li>Labor (human hours) </li></ul>
    33. 33. Digitizing for Employee Performance <ul><li>Broader access to materials allows employees to perform job tasks more efficiently </li></ul><ul><li>Centralized repository allows access from any location </li></ul><ul><li>Allows employee access regardless of frequency of content use </li></ul><ul><li>Ensures accuracy of performance due to access to documentation </li></ul>
    34. 34. Four Ways to Digitize <ul><li>To optimize resource allocation, digitize to fit your client’s needs: </li></ul><ul><ul><ul><ul><li>Preservation </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Use </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Access </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Commerce </li></ul></ul></ul></ul>
    35. 35. Digitization for Preservation <ul><ul><ul><li>Use lossless formats (such as JPG 2000, MPEG 2 “I” frame only) </li></ul></ul></ul><ul><ul><ul><li>Standardized formats across industries </li></ul></ul></ul><ul><ul><ul><li>Files tend to be very large and expensive to store and transport </li></ul></ul></ul><ul><ul><ul><li>Highest Cost in human hours </li></ul></ul></ul><ul><ul><ul><li>Video sizes: 30-90 GB per hour </li></ul></ul></ul><ul><ul><ul><li>Highest technology requirements for recipients </li></ul></ul></ul>
    36. 36. Digitization for Use <ul><ul><ul><li>High quality, but efficiently compressed </li></ul></ul></ul><ul><ul><ul><li>Examples include standard MPEG 2 (DVD format) video, and possibly Quicktime and WMV at higher quality </li></ul></ul></ul><ul><ul><ul><li>Files are large, but not as large as preservation files </li></ul></ul></ul><ul><ul><ul><li>Possible to transfer over internet or LAN </li></ul></ul></ul><ul><ul><ul><li>Video file sizes: 2-8 GB per hour </li></ul></ul></ul>
    37. 37. Digitization for Access <ul><ul><ul><li>Small file size, but typically lower resolution </li></ul></ul></ul><ul><ul><ul><li>Able to be streamed over internet or LAN </li></ul></ul></ul><ul><ul><ul><li>Cross-platform formats, including WMV, QT and RM </li></ul></ul></ul><ul><ul><ul><li>Video file sizes: 150-400 MB per hour </li></ul></ul></ul>
    38. 38. Digitization for Commerce <ul><ul><ul><li>Very small file sizes, but low quality </li></ul></ul></ul><ul><ul><ul><li>Used as advertising on websites, digital book previews (i.e. Amazon.com), or small scale music samples </li></ul></ul></ul><ul><ul><ul><li>Cross-platform, lossy, formats including Flash, PDF, and mp3. </li></ul></ul></ul><ul><ul><ul><li>Video file sizes: 20-80 MB per hour </li></ul></ul></ul>
    39. 39. To Consider <ul><li>Cost </li></ul><ul><li>Use </li></ul><ul><li>Condition of original </li></ul><ul><li>Migrating in future? </li></ul><ul><li>Type of organization </li></ul><ul><li>Begin with the End in Mind </li></ul><ul><li>Customize and Tailor </li></ul>
