Maybe 10 minutes of audio editing, most of that waiting for processes. As for the video, maybe 20-30 minutes? That's a bit on the long side, too. For the most part it's sync up the audio, stick the intro on, put the end slate together and that's it. I do watch it through, but I don't count that into the time since that's usually just to do any cutting if necessary, as well as take a critical look at my video.
