The never ending discussion about frame rates and lots more...

Not too long ago I was involved in a discussion about frame rates and this and that with a local "Indy" guy. He was showing off his T2i and some home made rig stuff. He talked about what they were shooting etc... and then he said the words that to me sounded like someone was pulling their fingernails across a blackboard. "We shoot at 24 frames for that cinematic effect." - Huh? Are you kidding me? So I asked for him to explain the "cinematic effect" to me. Basically, what does the "cinematic effect" look like? Or, what do you mean by "cinematic effect"? I waited.
