On2 VP6

my apologies for reposting

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

tried this on both windows xp and 10.4
jitter 1.5.2

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

thanks

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