Just wondering about delivery of the final product for video/film soundtracks. I assume you send whatever the director or mixer ask you to send, but exactly what is that, typically? Many small stems, like separate stems for strings/brass/woodwinds/perc? Or one stereo mix of the entire orchestra, with maybe synths/effects separated out? Do you send them with/without reverb? Who decides what stems are needed? Do you as the composer have any control over any of it?
Never done any real projects yet so just wondering what might be expected in this regard.
