Hi Ryland,

How much memory does your computer have and how many time steps you were 
playing?
If you can allocate 8G memory to the IDV, you should be able to generate 10 t0 
20 images sequence. Otherwise, you need to
write an ISL script and inside the ISL you can have a loop, and reload the 
bundle each time to generate only fewer images  and save these images in the 
same location, 
at the end you can group all images to generate animation. When you reload the 
bundle, it will free up the memory.
