Ultimately, the most time-consuming part of editing is rendering. Just about every editor has had to deal with watching a progress bar slowly move from 0% all the way to 100%. Sometimes this can take a few seconds, sometimes it can take a few hours. What I would like to know is, during those lengthy renders, what do you do? You may choose as many answers as you want. If what you do is not on that list, please leave it in the comments section.
