Anyone know this?

http://developer.apple.com/samplecode/QuartzComposerLiveDV/

it's a simply tool developed by apple that stream a qtz composition trough firewire....

the source code is included in the package... unfortunately I'm not a programmer and I don't know exactly how to do, but I think that is possible make a "qtz FX" putted in the layer manager that take the stream from vdmx and send it trough firewire...

reading the source code I understand that obviously there is a compression before sending the stream to firewire, and I don't know how intensive could be the process...but Apple's program work fine .

seems nice the idea of make a multi-monitor setup using one DVI and one firewire port....

this qtz composition could be used also for recording a showreel directly to a camcorder...

anyone know how to do / if is possible?

ive played with it. it is an application rather then a qc patch and it outputs video from a quartz composition already created. pretty neat stuff, but I am not an objective-c programmer either so I'm kinda stuck in the same position.

Sure, its possible. Ive been toying with the idea of making a QC plugin that does this, I should get around to making that, the issue however is DV is kind of a shitty codec, and limited to SD resolutions. it might make a good "poor mans" machine to machine hookup though.

please script king vade
give us this qtz plug in.
im looking despred for a solution to connect vdmx with 3l

hey! tnks for the reply!

hitmeyer - take a look to this http://002.vade.info/?page_id=4 .... i don't know exactly what kind of "connection" do you need... but probably this could interest you... Wink

KING vade - YEAH!! perfect! ;D i think that make a qtz plugin is the right way... today I opened the project of LiveDV in xcode;
provably it's possible just copy and paste some pieces of codes from "LiveDV code" to a "qtz plugin template".... obliviously making the right connection and checking input, output, variables ecc.... so stop going out with friends and advise your girlfriend... you have to work! we trust in you! ehehhehe Very Happy

thanks stefano but i know this allready.
i mean having 3l on 1 maschine and 3l on a second maschine.
so this plugin sound perfect for this thask but someone has to build it.
i am to stupid building it on my own.
but maybe ray/dave could do Smile

so please script wizards help the unscild hiltmeyer out.

Could this be applied to VDMX5 output, not just QC comps? Could it be an output screen choice in VDMX5's Preferences (Firewire output)? This would make VDMX5 a video production tool, not just a VJ tool, if it can be done.

What about a DV camera that can record anamorphic widescreen resolution (853x480) via Firewire? Then we could capture performances to a lower-res 16:9 format.

hi bsantoro! I've read somewhere in the forum that a "firewire output option" isn't a priority in this moment for the vidvox team... they are working at other stuff now... but make this qtz plugin could have the same results...

fot the 16:9 output; i think that this functionality could be implemented inside the plugin with options like PAL/NTSC; 4:3/16:9 (letterboxed, screatch )...

I'm a noob in Quartz Composer, and that's the first thing i thought about once i started fooling around with it:
How do you record what you're getting in the Editor ?

Firewire DV output would be great -- selectable between available dv devices eg. you might also have a firewire dv device as a real-time video input in the qtz patch at the same time Wink

Anyway: How do QC users usually do this? How do they record stuff for posting or whatever?
I know that you're supposed to be able to put a qtz compo's'n into QT player or iMovie and have it render it out as a QT movie...

QuartzCrystal is an application for rendering Quartz Compositions to QuickTime Movies and Image Sequences.

It supports 3rd Party plugins --- both Official and Unofficial API --- as well as unsafe patches. It also supports up to 64x Spatial Supersampling (Antialiasing) and up to 1024x Temporal Supersampling (Motion Blur) per frame. QuartzCrystal performs Temporal Supersampling. When you enable this feature, QuartzCrystal renders your composition at the specified number of time-slices for each frame, and blends these slices together --- resulting in smooth motion.

Please excuse my ignorance, but can QuartzCrystal render VDMX projects to Quicktime movies as a plug-in to VDMX; or is it strictly a stand-alone app for rendering Quartz Compositions only?

Hey brett,

Quartz Crystal does have some pretty nifty features that might make it worthwhile for rendering out QC patches into static movies, but you can accomplish the same basic task by using Quicktime Player (provided that you have Quicktime Pro).

Basically..
1. Open your QC patch in Quartz Composer.
2. Choose the "Export as Quicktime Movie" option from the File menu in Quartz Composer - the file that this creates is still rendered on the fly, but it can be opened as a regular movie file.
3. Open the exported file in Quicktime Player and export it to another codec as you would any other movie file- this will render it out the QC file and then encode it into the specified codec.

Thanks for the replies, guys. I'll give them a try.
I hope i can give back to the community,
once I've done something worthwhile!
