is it possible to output jpeg from jit.qt.record?

hi for a school project i am making a "sticker picture" application out of max msp jitter.

how it works is that i have a lot of different jit.qt.movie layers compiled into a final jit.pwindow.

to my understanding you can only output a jpeg from jit.qt.movie, so i can't use exportimage message function from my final jit.pwindow which is connected from a jit.lumakey .

i tried to use jit.qt.record but the most i can do is output a single frame of a .mov file.

anyone have any insight on how to overcome this? i'm guessing right now i could create something where the user then can import the new .mov frame they just made, then because it is jit.qt.movie they can export it into a jpeg, but that isn't that great of an option, if there is an alternative that would be much appreciated :)

thank you.
