9. WHY DIGITAL PRESERVATION?

10. RISKS TO DIGITAL FILES
LACK OF IDENTIFICATION
FILE CORRUPTION
STORAGE MEDIA FAILURE
SOFTWARE OBSOLESCENCE
HARDWARE OBSOLESCENCE

11. FILE IDENTIFICATION
robot.mov
high quality master
robot.mov
low-quality proxy
robot.mov
clip from Terminator

12. FILE IDENTIFICATION: OPTIONS
FILE NAMING CONVENTIONS
Sample: FR_05182015_robots_M_01
(department + date + program + purpose + ID)

13. FILE IDENTIFICATION: OPTIONS
FILE NAMING:
Include recognizable and relevant identifiers
Include dates
Use sequential numbering for version control
Use leading zeros to make sure files sort in sequential order

14. FILE IDENTIFICATION: OPTIONS
FILE NAMING:
include characters other than letters, numbers and underscores
use spaces in between sections of the identifier
make file names so long they become problematic for software
use the same name for two different versions of a file

15. FILE IDENTIFICATION: OPTIONS
Unique Identifier/GUID/UUID
Sample:
516b0360-b272-4005-b312-748542972f96

16. FILE IDENTIFICATION: OPTIONS
Checksum

23. TECHNICAL RECOMMENDATIONS
Analog-to-Digital
PRESERVATION FILE
codecs: 10-bit uncompressed v210, JPEG2000, FFV1
color space: YUV
chroma subsampling: 4:2:2
aspect ratio: preserve original (for video, usually 4:3)
wrappers: .mov, .avi
audio: 48 kHz/24-bit PCM
PRODUCTION MASTERS
codecs: ProRes, DV50, high-quality H.264
check with production staff what they find easiest to work with
ACCESS FILE
should be suitable for web playback or streaming
can be digital or physical (DVD)
codecs: low-quality H.264, MPEG-2

24. Born Digital
TECHNICAL CONSIDERATIONS
What formats can you support and play back?
What do your production teams use?
How much storage space do you have?
How confident do you feel mapping important characteristics
between formats?
Can you preserve metadata when transcoding?
How much computer time/staff time will it take to transcode?
What do you really need to keep?

25. STORAGE

26. MORE OPEN-SOURCE TOOLS

28. YOUR QUESTIONS
How can you get producers onboard early in the workflow?
How do you create metadata for older media when proper
documentation doesn’t exist?
How do you manage the volume with a very small staff?
