My previous post succeeded in finding out some information about
PC Hurricane.  It is a video capture board that can capture
(into 32M ram) approx 16 seconds.  Stores in RAM as 16 bit TGA.
Using "Xing Technology" software mpeg encoder, it appears to
take about 5 minutes to capture and encode a 16 second movie,
for a ratio of about 18:1 (18 hours to capture/encode 1 hour of
full motion video).

It appears that there currently is NOT an inexpensive integrated
video capture and mpeg encoder available?

Does anyone have a list of 24 bit color capture boards for
PC or MAC that capture in real time (ie capture a five second
movie in five seconds!).  Appears that currently mpeg encoding
would have to be a seperate process.?

Questions for self, not the company I work for.

There is more than one for the Mac that will do capture and JPEG compression
to disk in real time. RasterOps have their MoviePak add-in for various of
their video input cards, and SuperMac have their DigitalFilm all-in-one card.
I gather both of those were supposed to have started shipping this month,
but you might try contacting the vendors to find out for sure.

*Nobody* has got MPEG compression going in anything approaching real-time--
certainly not full MPEG compression, with motion detection between frames.

Okay, this is right, but the Xing sofwtware only encoder is running
at 1 frame/sec and this is not too bad I think...
