8. 1. Use as High a data rate as possible Less Bad Practice

9. Proprietary: -ProRes -WMV -Silverlight -DV50 Proprietary vs. Non-Proprietary

10. Non-Proprietary: -v210 (uncompressed) -DV (IEC 61834) -D10 (SMPTE 356M), -MPEG4 (ISO/IEC 14496) Proprietary vs. Non-Proprietary

11. 1.Use as High a data rate as possible 2.Use Non-proprietary codec Less Bad Practice

12. Understand loss

15. Zero loss is unacceptable! Except what we throw away!

16. 1.Use as High a data rate as possible 2.Use Non-proprietary codec 3.Understand what you’re throwing away Less Bad Practice

Google or Glacier, and falls over time It's not a TDR but neither are your hard drives on a shelf! Understand Storage Costs

18. High Performance Storage 2007 GBAVF cost for 2TB $100,000, 2 FTE 2015 GVAVF cost for 100TB, $100,000, 2 FTE managing 250TB of storage, 10TB/day, etc. David Rosenthal – “Cost of storage is rising because we're storing more.” http://www.unesco.org/new/fileadmin/MULTIMEDIA/HQ/CI/CI/pdf/mow/VC _Rosenthal_et_al_27_B_1330.pdf Understand Storage Costs

19. 1.Use as High a data rate as possible 2.Use Non-proprietary codec 3.Understand what you’re throwing away 4.Understand how much storage costs Less Bad Practice

20. If we're able to digitize it, though compressed, and it’s saved and accessible, isn’t it preserved? If it's worth retaining access to it, but we accept there's some loss because the quality is poor to start with - that is, image quality isn't what we're concerned about saving, it's the intellectual content - if we don't call it preservation, what do we call it? Janet Gertz Recast the question:

21. 1.Use as High a data rate as possible 2.Use Non-proprietary codec 3.Understand what you’re throwing away 4.Understand how much storage costs 5.Understand your actions - preserving the intellectual essence Less Bad Practice

22. Are we there yet? How will I know my institution is ready? Isn’t my preservation space already “special”? Can I afford it? How often will it be a problem? JPEG2000/MXF, AS-07

24. 1.Use as High a data rate as possible 2.Use Non-proprietary codec 3.Understand what you’re throwing away 4.Understand how much storage costs 5.Understand your actions - preserving the intellectual essence Less Bad Practice

25. 6. Exert yourself "advocate for archives” -make good choices -Who was ever fired for doing a better job? - Advocate for uncompressed - Adopt JPEG2000/MXF Less Bad Practice
