I am starting to realize that the video length doesnt really change the project time, except transcoding of course. I tend to REALLY edit and add effects to my short videos, and my long let's plays may have more commentary, annotations and in video texts, but less special effects etc. That being said I am becoming a editing addict and LOVE my software (LightWorks Pro). I have learned something new with it daily and hope that trend never stops as each video has something small added to it that I couldn't do the day before.
