if so can anyone direct me to help docs on how to install or activate that potential.

an extra question: 
does Jitter support On2 VP6 codec?

on2-vp6

but i am still searching for a way to say down a sequence of files or movie with alpha transparency preserved so that i can dynamically import into flash...

dynamic_alpha.pat (in the documentation)does this using a pack and unpack and the resulting png has some transparency...but when i use the same logic with video and a background subtract, the background is black

I would still love to export directly as On2 VP6 if there is any resource for installng codecs in Jitter pls let me know.

below is a sample patch with a switch to use the background frame as alhpa channel or a 1 channel matrix noise as alpha

tried this on both windows xp and 10.4
jitter 1.5.2

any suggestions?

The "getcodeclist" message to jit.qt.record might be useful here -- it 

will list all valid codecs on the system, with a name that Jitter will
