I have this editor that made me a montage and he sent me it only problem is he sent me it in .prproj i told him to go back and export it in mp4 he said he deleted all my clips and he wants me to pay for him to redo it and know i'm just stuck with a .prproj and that's all, I can't find anyway to convert it to mp4 or at least a file type that youtube accepts, i don't know what to do now.
