Preservation Options 1
• Past Options Were–Service Bureau–DIY analog video to miniDV or DVCAM transfer
• Now Conservation has–ITU-R.BT601 video capture using a computer

• Past Options Were–Service Bureau–DIY analog video to miniDV or DVCAM transfer
• Now Conservation has–ITU-R.BT601 video601 video capture using a computer
Preservation OptionsPreservation Options 3
Service Bureau– Send artifact to vendor -- loose physical possession– Cost $250-1000 per tape depending on format & output– No control over appearance
• image noise reduction• color corrections• compression or expansion of Luminance (Y) and/or Color (UV)
– Most vendors legalize video as a courtesy
Preservation OptionsPreservation Options 2a
DIY analog video to miniDV or DVCAM transfer–Collections
• 1000 - 20,000 tapes that need transfer• 10, 20 and 30 year old: U-Matic, VHS, Betamax and Hi-8 tape• can’t afford $250+ tape
–Opting to use an inexpensive & available method•(1) transfer to their miniDV camera via Video & Audio IN
– RCA jacks = composite signal
– about $1300, $5-10 per tape
Preservation OptionsPreservation Options 2b
(1) transfer to their miniDV camera via Video & Audio IN – RCA jacks = composite signal
– about $1300, $5-10 per tape
Preservation OptionsPreservation Options 2c
DIY analog video to DVCAM transfer–Opting to use an inexpensive & available method
• •(2) Sony DSR 45 DVCAM deck
– composite In & Out
– Y/C (S-VHS) In & Out
– component (YUV) In & Out
– small LCD for monitoring progress
– $3500, $10-25 per tape
Preservation OptionsPreservation Options 2e
• Value of the process– Failing video tape can be easily migrated– Original cassette in sealed bags for cool storage 40°C– Direct file transfer can be made over Firewire, no loss– DV (5:1) Format still is superior to
•U-Matic •Hi-8•S-VHS •Betamax•VHS
