Cameras and capture cards.
by Jaime Oliver 27 May '07

27 May '07

Hello all, I have to determine what cameras and capture cards are best for video tracking... Preferably, i would like them to work with as many platforms as possible (OSX, windows and Linux) and this are the constraints: capture cards: the least latency possible. I have tried some digitizers that used compressed firewire and they are too slow (too much latency). others like the turtle beach are uncompressed firewire and seem to be faster, however, so far cheap PCI cards seem to be faster for me, but the restriction there is that it has to use a slot in a computer and most are for windows only. Video Cameras: good color resolution, option to turn off auto-iris (and preferably more than 30 fps). I have tried a canon 3 ccd that gives good color resolution but only 30 fps. I also tried some CCTV cameras, but they have autoiris and bad color resolution (only composite video out). I briefly tried fire-i and they seemed to have low latency through their firewire out. I think you can hook them in series too which is also great unless latency increases. anyway, if anyone can share their experiences i would be very greatful, thanks in advance, Jaime -- Jaime E Oliver LR joliver(a)ucsd.edu www.realidadvisual.org/jaimeoliver www-crca.ucsd.edu/ www.realidadvisual.org 8693 Via Mallorca No. 19 La Jolla, CA 92037 USA -- Jaime E Oliver LR joliver(a)ucsd.edu www.realidadvisual.org/jaimeoliver www-crca.ucsd.edu/ www.realidadvisual.org 8693 Via Mallorca No. 19 La Jolla, CA 92037 USA

Couple of new list-abs
by Luke Iannini (pd) 27 May '07

27 May '07

Hi all, Here are list-remove and list-swap. [list-remove] is like list-delete, but it allows the removal of an arbitrary number of items. [list-swap] is a hybrid of list-remove and list-insert. It overwrites a portion of a list with another list of arbitrary length. I considered the name [list-overwrite]; I decided it was too long, but I'm open to suggestions. HTH, Luke

is there anyway to connect these two programs, i managed to use puredata netsend and receive to sen midi notes to quartzcomposer through a midi pidi pipe on the network but i would like to know if there is another way hugs bern. -- Raging_Synth Bernardo Gomes de Amorim - 2006 Confidencialidade de Correio electrónico Este email destina-se exclusivamente à(s) pessoa(s) a quem é dirigido e não deverá em caso algum ser reencaminhado ou reutilizado para nenhum fim a não ser aquele para o qual foi criado.

Maybe someone could make a pd patch to dynamically calculate this so that we can be sure to be ready for the arrival of ver1.0 ;) >Taking into account that Pd was started around 1996, assuming a >version number of 0.00 then, it now has reached 0.41 in 2007 and thus >will reach 1.0 in 2022. > >A different calculation is less optimistic: As the current speed of >version numbers is about 0.01 per annum, it will take another 59 years >to reach 1.0, which is 2066. > >Or Pd may do as Ardour did: Just jump from 0.9999... to 2.0 and leave >out 1.0 entirely.

Hi, I've used Krut Computer Recorder to record Java 3D applications, and I think the results are not so bad. Maybe you can use it to get a video of your GEM application too. pd-list-request(a)iem.at wrote: Send PD-list mailing list submissions to pd-list(a)iem.at To subscribe or unsubscribe via the World Wide Web, visit http://lists.puredata.info/listinfo/pd-list or, via email, send a message with subject or body 'help' to pd-list-request(a)iem.at You can reach the person managing the list at pd-list-owner(a)iem.at When replying, please edit your Subject line so it is more specific than "Re: Contents of PD-list digest..."

You need one that can grab opengl window (on mac x-snap pro and on win camstudio) and a POWERFULL macine :). 4 me that was the fastest way and i god quite nice results. check on wiki for more info. peace n.

i've used a few methods with various degrees of success: 1. screen recording as Nikola mentions. on linux there's xvidcap and others that i can't think of at the moment. running this as well as your application can end up making the machine run pretty slow - at least for me. 2. pix_write to save a series of stills that you can animate. this method works better for me than (1). plus gives me the added bonus of deleting frames that i don't want. e.g. when doing some video feedback stuff, i get some flicker - blank frames. i can easily sort all the saved files and delete these (significantly smaller file size than "good" frames). 3. similar to what Claude does - run svideo out of one machine and then record it onto another machine. since the machine creating the visuals doesn't have to also record or write images to disk, i've had the best results with this for cases where the patch is most demanding - e.g. patches doing both audio and video processing. best, p > -------- Original Message -------- > Subject: Re: [PD] converting gem patches to video files > From: "Nikola Jeremic" <nikola.jeremic(a)googlemail.com> > Date: Fri, May 25, 2007 5:33 am > To: "Claude Heiland-Allen" <claudiusmaximus(a)goto10.org> > Cc: pd-list(a)iem.at > > you can also try some of the screencast programs, i was using them > some of > them.
