can someone explain the following. I am working on a feature film. The mp4 of the film is exactly 01:28:44:10 long at a frame rate of 23.98fps. Everything is at 48kHz of course. I have exported a stereo downmix of this film and send it to the editor. He complained that the wav file is a bit longer than the film and therefore out of sync. And indeed the length of the stereo wav export is 01:28:49.741 (741 being ms). However, when I import this stereo export into my Nuendo session, it syncs up exactly with the length of the film. Where do the extra 5+s come from and go respectively?
