As you'll only have 650MB or so worth of storage on a CD, I can't recommend saving the video as uncompressed video, because sixty seconds of raw video at 640x480x24 would take up multiple CDs. Also, some PC systems don't have enough horsepower to handle playing back a bitstream that large in real-time.

You're best off using either a lossless codec with perfect image quality (like Huffyuv), or a lossy codec like DivX (set to minimum compression for maximum image quality).

I tested various codecs (including Huffy) in Poser a couple of months ago. Read about it in the Director's Cut forum:
