i placed my video in the timeline which played perfectly fine but when i put some effects, a red line on the top of the timeline would appear. i know that when there is a red line, it means that it is not rendered and same thing happens when i try to export it. there is this pop out window that says "error : MPEG format or something". i'm having a hard time finding a solution to my problem. i really need to fix this before the deadline.
