I haven't already tackled this problem, but here's my 2 cents...
Recommendation: Avoid proprietary formats
Interesting timing with this question - the open source 'Ogg Vorbis'
audio format has just today released its version 1.0 offering. It is
considered to be technically superior to the MP3 (Pro) format, and is
unencumbered with *any* licensing or patent issues. It only makes sense
to go with a non-proprietary format for digital audio archiving IMHO.
See http://www.vorbis.com/ for more info on Ogg Vorbis.
As a matter of interest, I came across the following exchange today in
one of the forums discussing the Ogg Vorbis release:
"WMA8 sounds better and it's smaller in size."
WMA8 is a proprietary format, Will. The beauty of ogg
vorbis is that it's Free. Not just free in terms of
"don't cost nothin", but free as in the sense of
"nobody can take it away from you". Proprietary
formats must never be allowed to become standards
(and no, I'm not putting down Microsoft or their
products). Why? Because they lock one in to a
proprietary platform. For example, I cannot listen to
Media Player files on my Linux system. So if I
nevertheless wish to hear them, I must either use
Windows or hope that Microsoft releases a Media
Player for Linux (cold day in hell). Now, let's take
something like RealAudio. This has been ported to
Linux. But what happens if Real suddenly decides to
stop supporting Linux? Or Windows? Or Macs? My point
is, we are at their mercy. This is hardly the stuff
on which to build a standard.
Food for thought...
P.S. I would avoid both WMA8 and RealAudio for much the same reasons
P.P.S. Not sure about video formats, but MPEG sounds like a good bet.
