First off you'd need a Mac with AV or Audio Video
features that include AV _input_ and the ability
to actually capture the video and audio, not just
the ability to run it through the Mac's monitor and
speakers.

Given that, you're looking at capturing at best
320x420 resolution and using old codecs because
any video capture hardware built into NuBus Macs
either can't handle the newer ones or software
capable of using them doesn't exist to run on
them. Even the high-zoot NuBus video capture cards
that can do 640x480 at 30fps are limited to the
older codecs because of the software thing.

About the best NuBus video capture system ever was
the Media 100. That puppy took two slots, used
a custom breakout cable and the hardware was
serialized with each copy of the software keyed
to the individual board sets. So unless you get
the COMPLETE Media 100 NuBus setup it's completely
worthless. I think Media 100 had an upgrade discount
to the PCI version if you sent them the breakout
cable from your NuBus Media 100 system.

I wish Media 100 would release a version of the final
NuBus software that isn't locked to the hardware
serial
and plans for building a breakout cable. That would
not cut into their current market because 99.999% of
video professionals would sit around waiting for an
old NuBus PowerMac and old software without all the
latest and greatest FX to chew on their data. It would
definately be a big PR coup for the company. :)
(It would also make all those sets of NuBus Media 100
boards minus cables and software suddenly worth a
few dollars!)

On the cheaper end there were some other NuBus
video capture cards but I think they're mostly
restricted to working with System 7.1 through 7.5.5.
Radius made some, so did Cinepack but they dumped
the hardware end to concentrate on codec development.

Does the LEM videocard list have anything on NuBus
video capture products?

At any rate you aren't going to be using DivX or
MPEG2 or MPEG4 on any NuBus Mac. And it would be
very tedious going on anything pre G3 or even the
sub 400Mhz G3 range, though you _can_ install a
nice PCI capture card and OS 9.x.x on any PCI
Mac with a 603/604 and make things work.

If you have only one or a few tapes to convert, your
best bet is to have some shop do the capture and
either put it on DV tape or some DVD recordable that
will playback in a normal DVD-ROM or DVD player.

If you have a big box of tapes to do then it's
worth spending the money for a decently fast Mac
(or PC) with a 60+ gig drive and a DVD recorder.
(I've seen them hit the $200 mark recently!!!)
Or you can go the DivX/MPEG4 route and use plain
old CD-R. I've seen some DVD rips to DivX on CD-R
that look thisclose in quality to the original.
640x480 resolution is all you really need for
playback on a TV. Some people like to use 800x600
for PAL TV but the native resolution for DVD is
something like 720x480 for all the major TV systems.
DVD playback on a computer doesn't care if its for
NTSC, PAL, SEACAM or whatever and usually it's
possible to convert the video and shunt it to a
composite or S-Video or SCART (common in europe)
analog output to display on a TV or record on a
VCR wherever you are in the world.

On the PC side, the "market" of freeware utils
for ripping, encoding, converting, disabling
Macrovision etc, etc is HUGE. There's an app called
DVDx that can rip and compress a DVD faster
than realtime on an Athlon XP or Pentium 4.
It can also do other video files so it's not just
for ripping DVD movies.

I don't know what's out there for the Mac that
doesn't cost an arm and a leg. There just doesn't
appear to be much interest in "non professional"
video software for Macs. For a starter, pop this
search into dogpile.com
+DivX +Macintosh
And you'll find what's out there for use with the
DivX codec. Note that DivX has nothing to do with
DivX the scheme for "renting" encrypted DVDs that
you'd pay for then get to watch as much as you wanted
for 24 or 48 hours, then you'd have to pay again or
"upgrade" the Disc to "gold" which allowed unlimited
playing. (That is, unlimited until the DivX scam when
belly up and they'll be shutting down their server
soon if not already, which will turn all DivX discs
into instant coasters.)

So if you want to be _cheap_ AND up to date with
video, get a PC box. If you want to do this with
a Mac, contact someone who specializes in video
capture, encoding etc with Macs. :) If you decide
to "go PC" on this project, start with www.divx.com
and get their DivX 5.0 codec.
