well, the first most obvious point is, non of us are professional "editor" hence, whatever video we shoot, we never get result like those :/ those are undergone editing and encoding cut paste etcetc, look for raw video from 7D,

the point is must be friendly, out of the camera if possible, undergone PP video are just another production video that many of us can never reach. just my 2 cent

just wan to let ppl know 5D doesn't only mean Canon....  same goes to 7D
