Unfortunately it doesn't seem like ML's shutterspeed options are affected by frame rate at all. You are stuck to 1/48, 1/63, 1/88 and 1/96 which are the more accurate readings from Canon's 50, 60, 80 and 100. It is a good thing that DSLR footage doesn't really meet TV specs because for TV 'close enough' isn't close at all.
Is there a way of getting more accurate shutter speed control with ML, or are we bound to canon's shutter speeds?
