pix_aging will put some 'noise' and scratches over your video.
well yes. allready looked up pix_aging. but somehow i wasn`t really happy with its results. what i am looking for is not dust and scratches but filmgrain. the grain pix_aging produces is not really fine structured. but anyway. i think i will try around a little more.
Also I found the pix_aging quite 'rough'. As Wolfgang writes, the filmgrain looks too much like pixel-blobs. Where I was looking for is more fine scratches, but the scratches in pix_aging are far to big, they are more like thick lines over the picture. Is there a way within pd to adjust the structure a bit? Or, is there a way in Gem you could draw 'scratches' [more like etching] on a picture?
The particle system is somewhat analogous to granular synthesis for 3D.
well the particle system would be a good thing. but there is the problem with openGl. a 3dimensional particle system (well maybe not in commercial 3d applications)
tend to be more like little lines then concrete pixels. what i am looking for is something like a 2d particle system which can be textured on geos. i think that could bring nice results in grain generation.
I agree. I was playing around with the particle system as well; but didn't quite get it to do what I wanted. But a 2D system could be interesting.

thanks for tips regards wolfgang
Are either of those close to what you have in mind?

hi
i am recently looking for a nice way to create quite fine structured graphical noise in gem. it should be controllable in speed as well as in grain size. well in general it should really be a noise generater. more something like a film grain generator.
anyone ever succeeded in building such a thing? i would be happy for any hints. maybe a grain object would be something for to do lists.
regards wolfgang
