[AV Media Matters] Digitizing Audio and Video-Really Big Post
We are about to embark on a sizable audio and video digitization
project. At this time we are just trying to figure out which direction
we need to go. Our goal is to create good quality digital archival
masters and then web usable surrogates. The pool we will be selecting
from includes 550 audio tapes (cassette and micro-cassette) and 575
video (VHS, 3/4-inch, and BetaSP). Although we know that only a small
portion will be selected for digitization, we are still reviewing the
content to aid our selection for digitization. The clips we'll be
digitizing can vary widely, from 1 minute to maybe an hour (although
bulk probably in the 5-20 minute range).
At this time, money isn't really an issue. We have a grant that should
give us plenty of cash to complete the project.
We have been doing some research, but would like to hear opinions as to
the standards we should be thinking about when creating the master file
for both the audio and the video.
We realize that this is a lot to handle, but any feedback on any parts
will be appreciated.
For the audio:
What are your personal opinions on the whole 16/44.1 through 24/96
How much audio, in minutes, do you feel is reasonable for a website? We
are hoping that we will have quite a bit of audio unless it becomes
difficult to serve or just unreasonable to offer, say 2 hours of audio.
In terms of formats, we have concerns about both file formats and media
What do you think about file formats for the master (DV vs other), for
high-quality user copies (MPEG-2, MPEG-4, etc)?
With media formats, would you feel comfortable with CD/DVD or would you
want to have a master backup on tape. How about hard drives?
How much video on a site do you think is reasonable to serve? One of the
content partners of the project said that they wanted to mount 10 hours
of video! (Honestly, the rest of the team thought this was way out of
line and was thinking more along the lines of about an hour or two tops.
We just want to know what the reaction is so that we can tell them, that
realistically, this is not the way to go.)
What are the pros/cons of streaming video vs. a downloadable file with
regards to quality?
We want to have both the audio and the video served as nicely as
possible. I will have to say that we are leaning toward streaming audio
and video at this point.
