Dance Preservation & Digitization Project

- 3 regional hubs (SF, NYC, DC)

- Formats

- Workflow - Archive or Dance company Hub Repository

- Case study: design and build of VHS station in Washington, DC.

Brief overview of digitization/ storage workflow

DPDP Digitizing Station in DC

Roles in projecto Project manager: basic overview design,

described needs, purchased and worked with local engineer to refurbish deck; mediation between admin and tech. In this case, chose deck model and brand, TBC.

o Video engineer: installation, training on monitor calibration and waveform & vectorscope, signal path documentation.

o Systems administrator, installing server software, advising on workstation workflow.

o Leadership, articulating vision, fundraising.

Preparation

• Resources at BAVC, history of digitization / preferred equipment already; knew what we needed.

• How did the station hardware fit into our digital preservation workflow?o Technicians creating SIPs acting as

“producers” in the OAIS frameworko Filesystem consistencyo Capture card and delivery format(s)

Page 6: L sorensen vhsaction_panel

Station design• Finding decks for purchase: eBay, some engineers

o Professional: Sony SVO-5800; Panasonic AG-DS555P; JVC-BRS711U

o Consumer: Panasonic PV-V4021; Toshiba M785; Panasonic AG-2530P Mitsubishi-HSU500

• What are important components when looking for a deck? o BNC versus RCA o S-Video vs. Component vs. Composite o Balanced audio

• “Know what you don’t know”

This perspective.. Informs this decision

• Formats in the collection; the most need based on selection policies/ collection assessment

• Playback deck choice: which format?

• Large number of EP or LP recordings • Playback deck, consumer, professional or both?

• Need for uncompressed or specific target file format

• Choice of capture card.

• Need for multiple playback decks • Consider purchasing a rack; video switcher or patch bay

• Need to output multiple formats at once (versus transcoding post-digitization)

• Talk with engineer about video processor

• Need for adjustment of luminance and chrominance (highly recommended)

• Purchase and training on waveform & vectorscope, and time base corrector.

Working with engineers as an archivist

What should you ask of your engineer?

• Deck refurbishment or purchase

• Recommendationso Recommended workflow, inspection practices.

• Trainingo Waveform & vectorscopeo CRT monitor calibration

Page 9: L sorensen vhsaction_panel

Training

• Detailed guidelines & equipment manuals

• In-person review and test tape(s)

• Waveform & vectorscope: a large focus

• Cleaning and deck maintenanceo When to outsource / when to clean in-house

• Looking for artifacts

• Metadata

• QCTools project; intention to make workflow and metadata open-source & easier

• A/V Artifact Atlas: http://preservation.bavc.org/artifactatlas/index.php/A/V_Artifact_Atlas

Handout contents

- List of video engineers, largely sourced from Tim Vitale’s AIC list and BAVC, sample budget, sample wiring diagram, example decks BAVC has used or does use.

- Keep analog video engineers in business

- DIY digitization is possible, if not preferred, especially for VHS format.
