PS> Just noticed that was only at 15 fps, meaning you only rendered 90 frames. For me 90 frames is only 3 seconds (which I render all-day long with all options turned on .. usually), as I ALWAYS render at 30fps. Depending on how much memory you have, it will take more than 90 frames typically. It's not consistent, but typically it will fail after 125 to 160 frames of animation. Once I got it to go as far as 270 frames. Depends on a lot of factors that influence how much memory is being used on each frame. -Tim
