Well, Ive used both, I use Jitter pretty much exclusively. I suggest
using PD Extended to help with the install, GEM is nice and fast for
most things, but is more suited to 3D (GEM is a wrapper for OpenGL,
not video exclusively, so inherits some of that in its design), than
to video per se. Its video effects are (maybe be?) somewhat limiting,
but it does support shaders (despite some issues), but not stream
processing (at least, no one has shown an example of that just yet,
and whats been tried has not worked), so building sets of effects that
arent out of box accelerated on the GPU may be of some issue - if you
want to go that route.

If you are willing to spend the money, I highly suggest Jitter.

I am a bit biased however, im simply much more used to working with
Jitter than GEM, but all I can say is I tried playing with video in PD
and felt I needed to look elsewhere for what *I* wanted to do.

But explore it, GEM has plenty of opportunities to be creative and do
awesome work, and you cannot beat the price. There is plenty of great
work being done with it.

Hi,

I am looking for anyone on the list who might be able to talk about
similarites and difference of PD/PDP/PiDiP/GEM and MAX/MSP/Jitter.

I am interested in hearing most about experiences with video
processing in PD.

thanks,

If you want anything that is much like Jitter's matrices you'd need GridFlow instead of GEM/PDP; for that topic it's the closest to Jitter.

(for more ordinary matrices there are some other externals, that may be more appropriate than GridFlow, such as IEM-Matrix, depending on the exact transformations that you want to do and what kind of data you want to work on: images themselves, various byproducts of images, or also completely different data (e.g. if you use Jitter for sound analysis in order to generate videos from it...)

hello,

i'm not really working with video. more with images and/or 3D. for my use, gem is 1000 time better than jitter. it's faster to develop, and you get better result.

as other say : gem glsl suport is not perfect. but jitter is far from perfect to.

gem is very close to your hardware/openGL. opengl has been disign to be very fast,effective and easy to use.

cyrille

p.s : segmented patch chord is in my opinion the 1st step to make unreadable patch.
