MEP stands for Multi Editor Project.
This is when a group of people work on the same song, video, like an AMV or MMV.
They work on different time frames of the project.
Can be classified as a collaboration.
1. Oh the AMV
? I'm working from 0:00 to 0:30, Stephen is working from 0:31 to 0:42 and ...
2. Me and the guys are making the MMV
3. Yo you done your part of the MEP yet?
