Hi Ben i am actually having a ball with GEM(g4) on my OSX box and using pix_video_ds on my winXP machine... linux is still too shaky for me with no way to get video in there. i am still at 7.3 on a sony vaio laptop and can't get ilink working and i just set up my SGIperformer stuff on there so i am not touching it alot of very cool stuff happening with vid in pd these days p.s. we just finished another global Access Grid perf with Korea/chile and indiana...dig http://apps.internet2.edu/
we have got to hook up pd with the AG

hey Pat,
I should have qualified my answer with, I use Gem almost exclusivly and I have little interest in using Jitter!!!
But you can do more technically with jitter than Gem, but a Gem-Gridflow working together would be really nice...

Ben i have to disagree I have seen and used both and GEM (at least the G4 build) is amazing. i will try jitter again, but they seem to embody their names when it comes to quality.

Hey Jhave,
I've only tinkered with jitter, but I know a lot of jitter users. First off Gem is A LOT easier to learn than jitter. The way you patch is much more clear and intuitive. This is becuase there is no matrix operation stuff as there is in jitter. This makes Gem less powerful than jitter. What do you want to do with the video? Are you doing any matrix stuff at all?
For resources I just taught 120 college students Gem in two classes, 2 hours each. I have the lecture online at:
http://www.ekran.org/pd/PD-Lecture.tgz
It's an interactive PD patch so you should learn lots. Also Chris Clepper has some tutorials on his site at:
http://taproot.dyndns.org/~cgc/tutorial_gem/index.html
There are a large number of Graphics/Video libs for PD including: GridFlow (matrix operations), Framestein (windows only), PDP (something more like softVideo), and PiDiP (nice extra stuff on top of PDP), and of course Gem.
I just did a performance in collaboration with a jitter guy this week, I'll encode some video and have it online at some point in the next couple weeks. (Bottom line is they work well together, and there is a nice aesthetic balance)
Mathieu and Gem-devs: I've been doing a lot of matrix related stuff with Gem lately driven by my PSO object, and its a little awkward. (Like interpolating 24*8*5 vertex positions etc..) With Chris's vertex array stuff is there a possibility of using gridflow for matrix operations to be passed onto Gem for attaching to openGL? I would be very interesting in seeing such a connection. Are either party's interested? I have some example patches to show off what I mean by awkwardness if required!

Hello PD-gurus,
I'm a comp-sci student and artist just learning Max and PD, and i am beginning a project involving video,
does anyone out there have any comments or suggestions on the relative learnability of Gem vs Jitter? (if so what resources exist?) and is Gem as powerful as Jitter?
all comments appreciated,
jhave
