Ok, so in either a rendering, or an exporting Premiere Pro CS5.5 project, or in the case of exporting media, also Media Encoder exporting file, my PC will unexplicably shut down. Just cut off, then slowly start itself back up. I shoot on the Panason Lumix GH2 (unhacked) , so I work with raw MTS files just dropped on the tmelne, usually usng effects lke Neat Vdeo, Magic Bullet Colorista II, and Mercalli V2 on several clips all at once(apparently I shoot for these wonderful plugins to fix my lazy shooting mistakes in post).This usually happens with efects laden projects, projects I need done all the time dur to the nature of my job as a freelance video editor.
