Multiple analysis of a single video stream within Max/MSP/Jitter

Good afternoon,

I have a patch that requires multiple instances of the following:

jit.pwindow
suckah

I want these objects to open a video stream from my firewire connected iSight. However, there will be around 5 instances of video analysis, each analysing different aspects of the video feed.

I have set up my video analysis tool and I have attempted to copy and paste it to create these multiple instances. However, it appears that only 1 video feed can be opened at any one point whereas I would like to have the single iSight feed appear in all 5 (for example) jit.pwindows!

Any suggestions here?

Thanks,

MadMaxMSP

Here is the patch Joshua. A web camera or video feed of some nature is needed. A colour within the jit.pwindow and suckah area can be selected and that colour is tracked. I'm trying to create multiple instances of this within a single patch so that I can track atleast 5 colours and therefore output 10 values (5 x X & Y planes).

Anyone with advice on where to take this? I would have thought simple copies and pastes of the main stucture linked to the original jit.qt.grab but this has not worked so far.

Thanks.
