Seems like this would be the default. So maybe it was just me being a bit premature in trying to change settings.

# The task

I'm working on an OBS recording of myself, where I wanted to replace a part of the video with another video in DaVinci Resolve 16 on Windows.

Cutting the old video and inserting the new video was done quickly, and left me with two video and two audio tracks in the timeline (see screenshot). The audio clips are processed separately in Audacity and were later imported (from WAV), and are linked with the videos before cutting, if that matters.

(I think) I then tried basically all alternatives I could find in the Deliver settings, threw quite a few combinations of "multiple" "audio tracks" "export" and "davinci resolve 16" at Google and the Video Production search, and also skimmed through the tutorial and reference manual of Resolve, but to no avail.

The only way that I could find to achieve what I wanted was to move the inserted clip's audio and video track to those of the original video. But I guess there has to be another "proper" way to do this, because my approach would e.g. not work for music.

The likely culprit is the Audio setting [**Output Track 1**], which should normally be "Main 1 (Stereo)", which is the default final bus/mix of the audio in the compiled video.

When setting it to "All timeline tracks" -- each audio track (stereo or mono) is rendered as separate tracks (stereo or mono) in the output file.
