Damn dude. That is a good question. I've heard it explained being similar to taking a digital picture. Its better to take a picture using high resolution even if its only to be edited and reduced in size later because it will always be cleaner and look better. Try editing of touching up a low resolution picture and you will notice a major fake look to things.

At normal speeds it is nearly impossible to tell the difference between 16 and 24 bit ADA conversion but when you slow things down to a fraction of a second and try to edit something there will be a huge difference in detail.
