On2 VP6

an extra question:
does Jitter support On2 VP6 codec?

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

cheers

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
jhave

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

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
understand.
