First paragraph – Actually, that’s a Canon, not a Sony. (I’m sure that’s a typo).

I’m not an expert on the progressive numbers, but you’re assumption that 1440×1080 is 4×3 assumes square pixels. The Canon H series are all wide-screen camcorders, so those pixels are 0.75:1, not square, and what you recorded is actually 16×9.

I’m guessing the last number (the 32 in 1440x1080x32) would be the number of bits per pixel (to record the color information). I could be wrong.
