So, I'm composing using Dorico for this movie, The Drowned Girl. I'm using a score-writing program because I have to present an actual score with/for my thesis for my PhD. I'm using Dorico because it will work with video playback somewhat reliably.
Problem one: if you change the video file Dorico will continue to play back the audio from the last video file with the same name. I don't know if Dorico is building a cached audio file for video playback or what, but when you make a new video file (and if you're doing film, you'll be making new video files), it needs to have a new name.
Mise-en-scène. I don't think I know what it is and I read the Wikipedia.
