I am using a T2i with ML latest build. I used to know how to switch between 1/31 second and 1/30 second video shutter speed when shooting video. I seem to forget how to do this without turning off ML. Would someone please refresh my memory on that. I seem to have the impression that I get better quality video of a computer monitor with a refresh rate of 60 if I use 1/30 second than when I use 1/31. I presume I could use 1/60 which happens to be unchanged, but I would need to double my ISO.
