The Rate Stretch tool is useful for the common situation of needing to fill a small 
amount of time.
3
The time-remapping feature is not found in the Effects folders. It is a common effect 
available on all clips by default.
4
Time remapping is best done on the Timeline; because it affects time, it is best (and 
most easily) used and seen within the Timeline sequence.
5
Add a speed keyframe, and split it by dragging away half of the keyframe to create 
a transition between speeds.
6
Select the clips on the Timeline that you want to change; then adjust the duration, 
being careful to select the Ripple Edit, Shifting Trailing Clips option.

LESSON 12
Acquiring and Editing Audio
Getting started
Audio typically takes a backseat to video, but it shouldn’t. Clear and well-edited 
audio is crucial to your projects. The best images lose their impact if the accompa-
nying audio is mediocre. Your first goal is to acquire high-quality audio from the 
get-go, both in the field and when recording narration.
Adobe Premiere Pro gives video producers and audiophiles all they need to add 
top-notch aural quality to their productions. The software has a built-in Audio 
Mixer that rivals the hardware found in production studios. The Audio Mixer lets 
you edit in mono, stereo, or 5.1 surround sound; has a built-in instrument and 
vocal recording feature; and offers several ways to mix selected tracks.
You can perform industry-standard edits such as J-cuts and L-cuts on the Timeline, 
as well as adjust audio volume levels, keyframes, and interpolation.
In addition, Adobe Premiere Pro is in compliance with two audio industry 
standards—Audio Stream In/Out (ASIO) and Virtual Studio Technology (VST)—
which ensures that it works smoothly with a wide range of audio cards and dozens 
of audio effect plug-ins.
