Technicolor just released a new Picture Profile for Canon DSLRs, and recommended that ISO be used in multiples of 160. Andrew Schär decided to test this using his Canon 60D, and found that in terms of the amount of noise present in the footage, ISO numbers that are multiples of 160 are best (i.e. least noise), followed by multiples of 100, and finally multiples of 125 being worst.
