Subject: newer2go

actually I would steer clear of this for general video on a laptop:

1) it requires a DV camera or deck to work (the card is only a data
transport... it doesn't do video on its own. so that adds at least $500 to
the cost (more likely $1000 - $2000 depending on the device you choose)

2) it won't work with max - even if you have it + a camera, you need an app
that has a DV -> QT software bridge such as Final Cut Pro/Premiere or
EditDV. (the nato.0+55 object may support DV in the future pending
testing/development)

A better all purpose cardbus/PCMCIA card is the IREZ Capsure -- only $99 and
has composite and SVHS inputs... they also are now making the "Capsure Pro"
about $400 -- which features hardware MPEG CODEC in & out -- note you must
have a PB3400 or latter for these cards (needs the so called 'zoomed video'
chips) -- the pro model looks very promising

Hi max/msp-ers,

I've just finished updating my granular synthesis application, and have put
it up for all to see at:

Hi,

Marcel Wierckx's Real-Time Granular Synth 2.0 very nice Max/MSP application
is available there:

<ftp://ftp.ircam.fr/pub/forumnet/max/MSP/applications/RTGS_2.0.sea.bin>

A short description of RTGS 2.0:

"...

An application created in Max/MSP which performs granular synthesis in
real-time. Needs a Mac G3/233 to run...

Hi,
Please check out the DIEM Digital Dance system at http://www.diem.dk
(click on "Products").
The system is designed for detecting angular movements on a dancers
limbs (elbows, wrists, knees and ankles), and wireless transmitting the
data up to 30 mtrs to a receiver where the measured datas are
transformed to midi (controllers).

Best wishes

Apparently the CapSure product has potential. I am currently looking into
supporting it for my forthcoming softVNS max external. (seemingly
forthcoming forever as I wait for ATI to get their new video cards
out!!!!)

DV is fairly hopeless currently if you want to use the video as a
controller, since the DV stream is highly compressed. It needs to be
decompressed first (by the processor) before you can do any analysis of
the image, so the overhead shoots way WAY up. G4's might reduce this
problem if someone develops a Velocity Engine DV decode...

Subject: Opcode ok?

Greetings gang,

I've been getting rumors galore regarding Opcode's eminent demise.
The credibility of *some* of the sources leaves a lot to be desired,
and others are more credible, so I was wondering... does anyone here
have any info to verify or discredit these rumors?

Cheers,

Chris

Tracking the dancers is hard enough, let alone amplifying their emotional
expression :-}.

All tracking devices have their (dis)advantages. Both Ultrasound and
magnetic resonance devices only operate over a restricted area with any
accuracy, typically a 10 to 20 foot cube. Ulatrasound is, of course, line
of sight, so as you suggest multiple tracking devices may be needed.

Also, you'll need to ask yourself what to track (where to attach) and with
how many degrees of freedom. Device to track position alone are cheaper
than those that track rotation around all axes--and may be over kill if by
"expression" you have in mind tracking velocity over time (i.e., gesture).
Keep in mind that it's the software not the tracking device that must
amplify expression; thus, you'll need to control how much information
streams in and how fast you can process it. Too many devices may create
serious latency--simple is clearly better. It also sounds like you don't
want encumber the dancers with too many positional devices--though there
are very sophisticated motion tracking suits for that, at very
sophisticated prices.

Finally, I've been informed by Those Who Should Know that if you want to do
unencumbered tracking and costuming is not important that code for video
tracking is readily available--dancers will need to wear luminous
appliques, gloves, or similar accessories on dark clothing.


Good luck.
