If you render as bmp frames you can render the time sequence at 5 sec to 7 sec or any value you like. Bryce will even number the frames correctly for you. If you die you can restart at the next frame number just type the time into the animation control win you start rendering. You still have to be able to assemble the bmp sequence to a movie. Animation shop that comes with paintshop pro will output AVI and there are freeware and probably better programs that can do sound as well.
