Hi All,
I'm new to your list and to PD and GEM. I am familiar with max. PD is so amazing! I'm very happy and having a lot of fun. Thanks to all who have contributed and I hope I can add something soon. I'm using PD 0.37.2 and gem 0.888-rc2 in OSX on a dual 1.8 G5 and It's SMOKIN! I had 6 streams of quicktime videos having all sorts of fun. (BTW-I also tried max and jitter demo and for some reason it was slower and crashed more... also I learbed a great way to capture gem output in OS X is Snapzpro (a screen grabber that can work with video).
?s: -I'm trying to give my patches memory and have read Frank Barknecht most excellent stuff about doing this but have not been able to get his patches going because I have no idea how to deal with (what to do with) makefiles and CVS and I need to instal zexy and osc. I have PD living in my applications folder. Could somebody explain how to do this or point me into a compiling sourcecode for dummies place? Or a maybe theres a kind sould who could UL their working OSX versions of zexy and OSC to an FTP.
-In GEM the audio from my quicktime video clips gets output is there any place to grab this audio and/or mute it (besides extracting it from my video clips or turning my mac's volume down)?
-Is there a way in GEM to adjust brightness and contrast?
Thanks so much in advance. Sorry if these are stupid ?s.

I think you are actually using 0.90. GEM is pretty well tuned for video processing on G4/G5 machines, which makes a noticeable difference.
SnapzPro is a really nice screen capture app, and it's good to know that it will record the output of the gemwin. I think version 2 is required for this because I had trouble doing the same with version 1.x. Snapz will run on a different CPU from GEM so it will be faster than writing files out using pix_write on dual processor machines.

There was supposed to be a way to turn this off and on, but that code never made it to the release version. That omission will be resolved in a future release, but for now you can use a workaround and change the volume using QTPro: Open the movie and hit cmd+j to bring up the movie properties. Select the 'Sound Track' listing in the 'Movie' pull down menu in the top-left of the Properties window, and adjust the volume under 'Volume' in the right menu. Save the movie and the sound should be muted.
I don't know if the QT audio will accessible to the rest of Pd at any point.
-Is there a way in GEM to adjust brightness and contrast?
pix_offset will change the brightness of a YUV image. The first value fed to the right inlet is Y which is the brightness value. I have considered an object for doing contrast and saturation for a while as it's basically just subtracting the center point (127) from the Y U and V, multiplying by a constant and adding back the offset. I suppose situations like this would make an argument for generic unary math objects or a pix_expr.
