jit.dx.grab write to disk codecs

cdriko's icon

hello
i'm trying to write on disk some video with audio
in differents formats, with the jit.dx.grab object.

I think that I use the correct synthax
(like:"write c:testvideo 25. mpeg4 max") but the video layer
is allays compressed with "no compression",
or in "yuv" if I change the "format" of the grabber.

(I'm using QT6.5 on win XP)

how can I really compress movies in the correct codec?

another question is:
Howcan I've got the video signal out during the writing?

thanks
