Tentative launch date: July 2022
Initial tasks:
research video viewers
research process for converting mp4 files into HLS upon ingest into digital collections
digitize more VHS tapes of varying lengths (at least one 1hr+ in length, multi-file objects?) for testing
gather more examples of digital archives video repositories in the wild
Users should be able to:
stream video files in their browser
download mp4 video files
view descriptive metadata about the content of the file and technical metadata about the file itself
search for video content the same way they search for all other digital collections content (limit searches to video, include video in all relevant faceted searches, etc.)
Live examples:

A 30-minute example (they may not have longer videos?) https://digital.hagley.org/RexKaiserTape2-1?solr_nav%5Bid%5D=a9f4d270738648345247&solr_nav%5Bpage%5D=0&solr_nav%5Boffset%5D=17
like the basic design (just video at the top, metadata at the bottom)
Hagley has a field for information about the digitized file (“digitization note”); we should have somewhere to put this metadata
Current VHS digitization workflow:
VHS digitized in real time into preservation and access copies
preservation files: ffv1 codec, AVI wrapper.
Stored on the M:\ drive for now.
Eventually all VHS tapes will go through this process.
File size estimate: 25.4 GB for approx 25 min of video
access files: h.264 codec, mp4 wrapper.
Stored on M:\ drive for now in “access” folder.
mp4s created in house as part of digitization process if requested via R&R or intended for digital collections.
File size estimate: 164MB for approx 25 min of video
Questions
thumbnail generation?
file size limits
re: file size limits, if over a certain size, break file into multiples?
ongoing discussion about costs for storage, conversion to HLS, access/streaming at point of access, fixity checks
reminder that we’ll need to tweak/add to some of the metadata drop downs (genre, mostly)
