I almost always render movies as a series of images. If there's a problem, you can just begin again at that point, instead of starting over. Also can archive the images and go back and use them for another format, size, compression level, or other uses. If you've got QuickTimePro (a good deal at $29) you can assemble the sequence of stills into a movie in a snap. HTH - Elisa/gryffnn
