At the moment I am working on a Patch that is functioning as a basic live-performance / live-editing tool.

I am working with with two different playback channels in order to freely combine a set of preloaded clips, mix them, and apply an effect-chain to them etc.

As a playback-unit i use two instances of a (poly~) player patch. Very similar to the poly~ -based player in the Video-Processing system Tutorial by Andrew Benson (

In this setup I need to able to playback every file from both of my poly~ objects.(in order to be able to combine one clip with every other clip from the set - including itself.)

At the moment I pre-load every clip twice (once by each player) which lead to a huge need of available RAM.

Does anyone know if it is possible to pre-load a video clip once an access it from two different jit.qt.movie objects independently. Very much like i can access a named matrix from different places?

That would reduce the amount of required Ram by 50%.

thanx for the hint. it is a very useful approach.

I'm facing a similar problem, and Jitter is a new world for me.

I already looked at QT examples and Andrew Benson VPS tutorials.

Is there a way to capture the output of several quicktime objects inside one poly~?

So imagine, several QT objects playing at the same time inside one POLY~, it could be 2, 3 or 20 for instance, how would I MIX or SUM the output of each active QT instance playing? Is this possible?
