QC Actors

[mark]

No problem. Good for all in the community to understand. And the next time your students complain, you can just hand them a printout of this. ;-)

I am going to copy and paste this on to my blog is thats ok Mark? I get the odd question and private messages about Quartz.

No worries Graham... spread it around!

Thanks for the thorough explanation Mark.

I'm having an issue with QC Actors with the moment.  I have 2 QC patches that both work fine in QC itself - dont see ay errors raised anywhere.  When I put them in the /Library/Compositions or /System/Library/Compositions folders, one shows up in Izzy and works ok, but the other does not appear in the actor selection list.  I can drop the one that doesnt show up in Izzy into CoGe and it plays fine.  I know its not much to go on but, anyone have any ideas?  Thanks

Does the one in question require a plugin? Some Quartz files (.qtz) files have a plugin which is built for them specifically. You often need the plugin in order for it to work/appear.

Hi guys! Sorry to bother you, but I can't find how to use QC compositions as Izzi actors. I put my QC composition into all folders that Mark indicated, but nothing happens. I don't see anything, even original QC compositions from Apple. I precise that I use an IsadoraCore 1.3 version, my computer runs with OS X 10.6.8 and all file pathways are selected in Isadora Preferences. What am I doing wrong ? Thank you for your attention.

Thanks Graham.  I created the Quartz patch myself using only standard QC elements, so no plugins should be required.

BTW the patch was created under OS X 10.8.1 (Mountain Lion), and I've have been having some 'issues' (ahem) since upgrading, things like random QC crashes, spinning beach balls at times I hadnt seen them before & so on.  I just mention that in case there's something different going on with 10.8 that might be causing this problem with the QC patch not showing up in Izzy.  (I will reiterate that the patch does operatie without error in both QC & CoGe, and I was able to create a MOV file from it in QC).  Thanks.

@Fred2s
The version you are using is called IsadoraCore but did you buy the core video license, for extra $ 25.-?

Best,
Michel

Hi Michel,

Thank you for your answer. It's not me who bought the licence I'm using. I believed that if you can use the Isadoracore with a licence, it's that you have the core video licence, because a basic licence would not run with Isadoracore...

I'll buy the right licence if we don't have it already.

Thanks again. Fred.S.

In case anyone is following this thread, I did finally get the Quartz patch working in Izzy by recreating it in QC from scratch.  Must have been something weird in there that was causing problems.

After getting it working, I modified it to publish 2 inputs for video and photo inputs.  When I replaced the patch in Izzy it wouldn't function at all.  Removng the inputs allows the patch to work.  Has anyone had success with a QC patch using inputs from an Izzy actor?  Thanks.

Dear Eric,

Please send me the QC patch in question to my personal email. I'll have a look -- though I'm a bit behind with various patches from others I need to examine. So it may take a few days.

Best Wishes,

Mark

@ Mark,

did you do a patch "v002 Rutt Etra isadora"? I have the Rutt plug-in but was not able to put the QC in Isadora,...

[Lanz]

@bruper I've got this running i can't attach qtz file here but i can email it over to you.

attached is a picture so you can copy the settings of one of the many different things you can do with Rutt Etras effect, this spinning point cloud style thing i never get tired of :)  if others would like this effect, ill put it up on my site or make a little clip explaining. Its pretty straight forward to adapt the original rutt etra qtz patch if u know QC.

best, 

Lanz

Kinect and Rutt always delivers a nice effect ;-)

[bruper]

Thanks for Lanz last night.
So it seems that I may have a potential for troubles here (beside the fact that some are not visible in Isadora)... could please someone be so kind to advise me what I'm doing wrong here?
I have 1 QC folder in the user/library/graphics, 1 in ~/library/graphics and then the ~/library/application support/freeframe
are all in the right place or???

[bruper]

oh and I forgot to add this fourth as well:

[Skulpture]

.qtz files need to go into the Compositions folder. (see image)

Plug-ins need to go into:

/Library/Graphics/Quartz Composer Plug-Ins/

[Skulpture]

So .qtz and .plugin need to be in two different locations.

I often restart my machine when chaining things like this to refresh the system and library.

Hope this helps.

[bruper]

thanks Skulpture, It's incredible that I saw that screen preference so many times, I even deselected the system option for speed without having anything in none of the /compositions folders... But I should leave the FreeFrame folder content as it his right?

[Skulpture]

Yeah leave freeframe plugins folder as it is.
