+Going from `medium` to `slow`, the time needed increases by about 40%. Going to `slower` instead would result in about 100% more time needed (i.e. it will take twice as long). Compared to `medium`, `veryslow` requires 280% of the original encoding time, with only minimal improvements over `slower` in terms of quality.

+Using `fast` saves about 10% encoding time, `faster` 25%. `ultrafast` will save 55% at the expense of much lower quality.
