0: Not Started

I finally succeed in getting two iSight firewire camera (they are so expensive ! But fortunately, someone lend me one for a couple of weeks). I want to test a couple of technics using two sources with OpenCV and other great Kineme Plugins (The firewire bus seems to be quickest than USB, that's why i'm getting iSight Camera). That' the good news !

Now the bad news... Quartz Composer doesn't seems grabbing them both ! I use the special AudioVideo Kineme patch instead of the native QC's Video Input to get those two iSight right indexed, but it doesn't works... I only could get one source at a time. I could get the picture of the first or the second iSight but not the picture of the two iSight at the same time. In the Video Input Patch settings i could see that the two iSight are recognized, i could select them, but when i change the settings only one iSight is displayed at a time. I'm working on a MacPro. Could it be a Firewire bus matter ? Could i plug two iSight on the same FireWire bus ? On the MacPro, i use the front side Firewire input and the back side FW input for the second iSight. How could i get two image with those two iSight ? I got this hardware for a few time, and my test period is very short, so thanx for your help !

I am using Particle Tools v0.2 on Mac OS 10.5.5, QC v.3.0.

I have a little system where an emitter is emitting more emitters which emit particles. I checked the particle count and that's not what's causing the crash, btw. There are a few forces, a couple of winds, or a wind and a vortex.

I also have a collider with a face structure that I ganked wholesale from smokris' "hose" composition.

Then, if I remove a force and/or the particle while the viewer is running, it crashes. Usually if I delete the patch outright it crashes right away, whereas if I disconnect it, it crashes the next time I hit stop on the viewer.

So, summary. Three observed conditions:

1. # of objects in scene ≥4
2. ≥2 forces
3. Collider with smokris' faces structure

Several possible actions:

1. Delete particle while viewer is running
2. Remove ≥1 object (sometimes it survives one but crashes on the second time) while viewer is running, then stop viewer.

ALL of the conditions + EITHER of the actions = INSTANT crash.

The End.

When I save a file with the spline patch in it, sometimes the initial values of fields in the spline patch change (0 goes to something like 2.755e-40 or even null). If there is a connecting patch then the value gets changed and the problem isn't noticed, but for "unpiped" fields the changes cause issues. I do not know how to reproduce the problem, as it only does it on some saves. It may have something to do with using Save As and overwriting the original file. It does change the same fields to the same values every time except when major changes happen to the file. This only happens to the spline patch and it has happened for other versions of GLTools. It is an easy fix to change them back although time consuming. In the inspector screenshot all the Z values should be 0 and the X values should be a two digit decimal. Some of the Y's changed but as soon as the composition is running they get modified. The last two images are what it looks like with the changes and what it should look like. If uploading the .qtz file will help, I can.

I have heard that vade is doing something like an ichat plugin...

Hello Composers. I have a little request, i think is easy but i don't know enough. I want a plugin to put in VDMX (like the randomOnPulse.qtz pluugin) that let me know how much time i left in a gig. Some plugin with a place for put the total time of a gig and a bar show the elapsed time. Could be nice for best use of differents resources in a session.When i'm Vjing i'm really lost in space, i don't know what time is and is hard to me to calculate normally, sometimes i dont know at what time i start... anyway, if anybody knows how to make it... thanks! I think could be a nice plugin to put in VDMX. cheers

ps. really sorry about my english...

Hi, The KinemeAudioPlayer Patch doesn't export Audio in QuartzCrystal.

As already stated before me there is no real Audio Support in Quartz Composer. The MovieLoader doesn't play Audio, but exporting the audio and put it in a seperate KinemeAudioPlayer works fine for the length of my Composition (26 sec.). But there isn't Audio in the Export. There isn't Audio in the DV Firewire Exporter Sample of Apple.

I now try to get it "batch applied" after the rendering is done.

I developed a few ideas for batch rendered movies.

I would really like to have a SafeMovieLoader, but since loading remote RSS/XML is also restricted in QuicktimePlayer, I would love a SafeWrapper, where I can load unsafe Patches, maybe including some security measures as restricting the SafeWrapper to a single Installation, since I only need it for running my own stack of Movies. Since such a Wrapper would need Installation anyway, it could include information as my Name, and it might only work with Compositions having my name in the Metainfo.

on the other hand, a batch mode (maybe using command line, Apple Compressor or Hot Folders would be the perfect solution in QuartzCrystal.

Hi, I just bought the QuartzCrystal License this week, so maybe this is a beginner mistake:

I did export a composition to a 26 sec. DV-PAL movie. The composition includes a background coming from a MovieLoader, since I don't know much about exporting my composition with alpha to be applied as overlay onto the movie.

I did take two screenshots, they are 46 frames apart, and there is nothing that indicates the reason for this little black hole in one line.

If you need the full export, or another composition exported, please let me know.

Hi , i would definetly state that QC lacks output to physical devices, such as lighting fixtures (or explosives...). DMX protocol is the mostly used in "pro" environments, nightclubs or festivals, theaters... However, most DMX usb cards that you can plug to your mac use a FTDI chip, which is crappy, and which is apparently from a company you had problems with... This has led the development of a potential " DMX usb" patch (for the enttec one that smokris owns) to nowhere... since it uses the serial port for communications.

After some chat with one of vvvv's DMX supergod (aka kalle), it just seems that the handier and easier protocol to deal with DMX is now Artnet, which uses UDP packets to transmit DMX information.

Have a look at this (quite cheap) card from Enttec, that takes UDP packets as an input and outputs DMX... http://www.enttec.com/index.php?main_menu=Products&prod=70305&show=descr... note that there are plenty other cards (from 100$ to 2000$) from other manufacturers.

So I'm thinking: if some really need DMX output from QC, how about considering an Artnet patch - that is virtually compatible with ANY artnet hardware ... ?

here's the ArtNet spec.: http://www.artisticlicence.com/WebSiteMaster/User%20Guides/art-net.pdf

I normally use soundflower to route the audio from any audio playing app into QC and use the standard audio in to do frequency analysis and then do audio-reactive stuff in QC, but in view of the talks going on at http://kineme.net/Discussion/GeneralDiscussion/Recordrealtimeqtzmidiinpu... it would be great to have frequency analysis on a Kineme Audio File Input patch as well - so we can load an mp3 and do a bunch of audio reactive stuff on it with frequency info etc. Maybe this already is possible somehow, but I dont know...
