In part two of my Premiere Pro tutorial on the Submix in the Audio Track Mixer, I take a look at the second way you can use a submix is to send your audio channel directly to your Master output and partly to the Submix so that you can control the amount of the effect you are applying to your audio. Click here for part 1.
How much of the effect is sent to the submix
Why would you do this? Well, say you have several voices in a scene all with local mics, and you want to add a reverb to the scene to make it sound like the people are all in a big room. However, the people are at relatively different distances to the camera, which would mean that the people nearest the camera would not need as much reverb, while the people furthest from the camera would need more reverb to make it sound authentic.
How do you control this? Through a submix.
All the channels go to the Master channel in Premiere Pro, but also each channel has a different amount of the audio sent to the submix which has the reverb effect in it – which then mixes finally with the Master. This way you have plenty of the good local audio but also the ability to mix back in reverb in proportion for each person in the scene. And, as with all channels, the submix also has a fader so you can increase or decrease all the added reverb to suit.
Submixes also have automation modes!
