CHAPTER 11 324
Producing Final Video
Audio in the EDL
Because Premiere works with files on a computer instead of tapes, it controls sound in a way
that differs significantly from traditional editing systems. Traditional tape-based editing
systems are designed to record from (and to) one or more audio tracks on the videotape
or onto a separate audio tape recorder. Premiere provides up to 99 audio tracks in the
Timeline for placement of audio clips; however, when you play or export video, Premiere
produces a single track that can contain more than one channel (such as left and right). In
Premiere, mixing of audio tracks is controlled by the fade and pan controls that accompany
each audio track. The standard EDL has no way to mix sound, except for the mixing that
occurs when one audio source dissolves into another audio source.
To take advantage of multiple audio tracks on videotape, you can define which audio tracks
from Premiere are mapped to the available tracks in the editing system. The following options
are available when you choose an EDL option from the bottom of the File > Export menu
(except Generic EDL) and click the Audio Mapping button (see “Exporting an EDL” on
page 318):
Audio Follows Video
Causes the audio and video to be listed together, according to the edits
made on the video track: where the video cuts, the linked audio clip cuts; where the video fades,
the linked audio fades; and so on. Premiere processes the video edits, then processes the audio
to match, and lists the result in the EDL. The audio fade and pan controls are ignored.
