User string input

andrea379's picture

Dear forum, I'm developing a composition for a university exam. I'd like to build a string that user can modify by keyboard generating a specific directory scanner. So I'd like to call a specific 3d file sited into a folder by typing on keyboard. I'd also like to specify tags/categories for each folder because of the specific question that user will make typing.

I've already set a part of the string using the directory scanner patch, so the user can just define the last word of the input string. What I miss is to call the second part of the string, that in this case will contains .dae files, or folders containing jpg.

Thanks in advance, kind regards.


moving head mesh with webcam

toskascream's picture

hi everyone, I've created a 3D model of an head with maya and i've imported it in QC. The idea is to make the head's eyes (but also the entire head) moving and following the movements of a spectator. It has to be like the head is always watching you no matter what movement you do. Which patches do I have to use?

I'm new with quartz composer, I've downloaded the CVTools plugin and I've found patches like motion detector, but i have non idea about how to use you have some tips, tutorials, links or everything useful for my project?

help me pls :) thank you

how to offline or non-realtime render an iTunes Visualizer

boyfriendacademy's picture

I'm trying to turn some of my original songs and remixes into music videos by using music visualizers.

The screen capture method using Snapz Pro X to record an iTunes Visualizer isn't producing great results for me. I've tried tweaking the settings but my trusty old MacBook Pro just isn't capable enough to both simultaneously render and record 30fps 1920x1080. Here's the best I was able to achieve, at 1280x720:

So I started looking into offline or non-realtime solutions and came across Kineme Audio Tools. I've looked over the examples but I haven't been able to figure out how to take a Quartz Composition that's designed to be a realtime iTunes Visualizer (for example, the Jelly visualizer that comes with iTunes) and convert it to a non-realtime visualizer using the Kineme Audio File Input. Can it be done? I'm not a QC expert, so any help would be greatly appreciated.

And instead of using Quartz Crystal, I was thinking about trying the Quicktime Pro render method as described here: just because it seems easier.

I don't necessarily need the audio track included the rendered file. I can add the audio later through Final Cut Pro.

Pursuing a non-QC route, I was able to find a cool offline audio reactive visualizer done in Processing by visual artist Pedro Cruz that rendered a sequence of PNG images that could then be combined into a video using Quicktime Pro "Open Image Sequence". This method allowed me to create a beautiful 1920x1080 video at 30fps. Because it's highly-detailed, I rendered and edited it using the ProRes 4444 codec. Unfortunately, YouTube's h264 transcoding doesn't really do it justice, but you can get the idea:

Any QC or Processing artists out there that would like to collaborate with me on more music video projects like this? Right now I have about 5 more tracks I'd like to turn into videos.

Help with particle size adjustments?

bbinkovitz's picture

So, I am working on the attached composition and I want a way to adjust particle size over time. I want the particle source to spit out particles of varied sizes. All I've been able to figure out so far is how to make all of the particles on the screen grow and shrink in unison by changing stuff in particle render: structure, but that's not what I want. I have also tried changing the size, mass, and area on the generated object itself, but this seems to have no effect. Ideas?

Force patch demo composition

Here's a little demo composition I put together that shows how to use the Force patch (new to Snow Leopard.) It's not very well documented, but you should be able to figure it out by looking at it. Plus, it's kind of fun to play with, if nothing else. Enjoy!
