1) Using 60p footage on a 24p timeline, I can't see a difference between footage that is slowed down by selecting "Speed/Duration" and changing it to 40% and taking the same clip and changing the speed by clicking Modify>Interpret Footage and setting the 60p clip to 23.976. The resulting clips are both smooth and to my eyes look identical in every way even going through frame by frame. Are these two methods really just doing the same thing?
Back to your original question, I have found the results of using Speed/Duration to be identical to using Modify > Interpret Footage in a few tests. Have you continued to find that to be the case in your experience?
Also, what shutter speed do you generally use?
