When editing, you're constantly adjusting and re-adjusting the audio levels of dialogue, music and sound effects. But while the mixing windows and rubber bands are good for final mixes, they're far too slow and cumbersome for the initial edit because you have to manually click keyframes and move them.
Here’s how I do my quick and dirty sound mixes while I’m editing.
I put very short fades at the beginning directly when the dialogue starts, and a longer transition at the end so it gradually returns to full volume. Experiment with what sounds good to you.
This method is great because instead of using the mouse to move keyframes, you can use all the trimming keyboard shortcuts at your disposal in order to move the transition points if the dialogue should be moved or even deleted!
