Hi.

        I have an Performer application based on perfly. It's purpose is to fly
over a
golf field full of trees (billboards), houses (simply textured) and so
on... The scene is
quite complex, because the Onyx I'm using can't maintaint 15 fps.

        However, I want to record each frame for future video editing. So, each
frame, I save
my position and orientation in a file. When I want to save each frame, I
just read the file
and snap one image for each frame.
         
        So far so good. The problem is that when I see my images displayed at 25
fps in Fire,
or any other video editing program, my film is very bumpy.
        I don't know if the problem is when I produce the coordinate file or
later, when
I snap the resulting images.
        Now, what is causing this? My guess is the PFPHASE option in perfly.
I think it would be the right option to use PFPHASE_LOCK at a slow rate
when saving to
the file, so there would be no missing frames, and use PFPHASE_FREE_RUN
when
snaping the images read from the file.

        However, this did not work very well.
        Has anyone already faced this problem yet?

                                Thank you
