I have been working on a short film, and have just received the final mix (as a Protools output) from the audio posthouse. They sent me two stereo files and a folder of 5.1 files. I currently just want to make a master copy of the film using the stereo version. I imported the two files (marked L & R) into the timeline. Do I just create a stereo pair? Or pan one left and one right? Or something else?
