This is the most important role. Without editors and mixers and others we cannot make videos. All that is required of editors is that you can make Sprite videos with a variety of backgrounds (E.g. MEPs, Animations, GIFs, Pictures...) and add music over it. Also if you could make videos with the Dr characters faces over people in music videos that'd be great. And for mixers all that is needed is the knowledge of how to make a song Karaoke and how to edit separate lyrics into one audio clip to match the original song.
