Sometimes you need to make the DCP from a video file that has separate audio mono tracks.
A DCP 5.1 mix is often delivered as 6 mono tracks in 24-bit 48 kHz wav format.
To convert them to a 5.1 timeline track that can be used in a DCP, you link 6 mono tracks as 5.1 in Fairlight. This tutorial shows how you do this.
You can also make a DCP in Resolve from a video file with QuickTime/interleaved 5.1 audio. Read more in this post.
