sorry sledge, but you're wrong there. reg8mm (actually double8) is the one made from split 16mm. they both only have sprockets on one side. super8 has smaller sprockets. that's the only difference, allowing more picture area for s8. many 8mm cams are "double8", where you got a short (usually 25') roll of 16mm. you shot it for 25', flipped it over at the end, shoot the other side of the reel, and when you send it for processing, they split the processed film down the middle and splice them together, sending you 50' of 8mm film.
the kind of film with sprockets on both sides is reg16. (sometimes.) super 16 can only be single-perf, but reg can be single or double, as less of the neg is used for picture. not sure if you can even buy double perf 16 anymore. high-speed cameras often needed double perf to be able to achieve decent registration at their wicked-high speeds. but "double 8" cams are double perf, and then the processed film comes back single perf, and noticeably skinnier.
i'm not getting into 35 right now.
also, reg8, super8, and reg16 all use the same aspect ratio. (4:3, or 1.33) the picture area just gets bigger in size as you go up (in the above order.) but they're all the exact same shape ("aspect ratio" basically just means "shape.")
