Scott, thank you.
I am already working in sequence mode. The data I am working with is
lunar data from the lunar reconnaissance orbiter LRO. I am taking
data from the laser altimeter instrument on the spacecraft which is at
very high resolution and constructing the lunar surface topography and
then using data from another instrument, a neutron spectrometer which
can give us an idea where the hydrogen (water) is located, overlaying
that data on the surface and coloring by it.
I made animations on a 32 bit windows machine last fall in a similar
fashion using lower resolution data with great success and no
troubles. I am using a 64 bit machine now with 12 gb of ram, which is
why I was wondering could the rendering be getting way ahead of the
writing to disc, not waiting for some buffer to be ready.
I've read in the manual about the temporal interpolater but not sure how
to apply this to an animation. I have about 7 camera positions and am
doing a slow orbit about the north pole of the moon. The camera
positions appear to be interpolated just fine. It's simply that if I
render a few thousand frames, midway through the resulting avi, there
are frames where data seems to be lost.
thanks again,

Maybe you could try writing individual images, and then stitch them together
using some free software? As far as the individual frames goes, try opening up
the Animation View, change the mode to Sequence, and the number of frames to
200. Next, try Filters/ Temporal/ Temporal Interpolator.
If this doesn't save properly, please let me know what type of data you are
using, and I will look into it.

Would anyone have any knowledge of how to control the frame rendering
rate when saving an animation? I notice that if I make an animation
at 5 - 10 fps, the resulting avi file looks perfect. However, if I
use the same animation sequence and render at 20 - 30 fps, the resulting
avi file has many holes and greyed out areas in the frames beginning
about half way through the animation.
I'm wondering if it is possible for the frame rendering to get far
enough ahead of the IO writing to disk such that frame information can
be lost? If the buffer that is holding the frames renders fills up,
wouldnt it wait for IO writing to disk to catch up first?
thanks,
