Specifying source and target tracks
When you add clips to the Timeline by dragging, the clip is added to the track and time
position where you drop it. However, when you add clips to the Timeline using Monitor
window controls or by using the keyboard, Premiere cannot assume exactly how and where
you want a clip to be added. In such a case, you must specify in advance the way video and
audio tracks are added to the Timeline. By default, both source audio and video are added;
in the Timeline, the Video 1A and Audio 1 tracks are the default target, or destination, video
and audio tracks. In the Timeline, the names of the target video and audio tracks are bold.
You control how source video and audio are added to the Timeline using the Take icons
and Target menus:
•
The Take Video icon ( ) and Take Audio icon ( ) control the source clips. They prevent a
particular source clip’s video or audio track from being added to the Timeline. For example, if
one clip contains video you don’t want to use, you can specify that the source clip will provide
only audio to the Timeline.
•
The video and audio Target menus control the video program in the Timeline. They govern
which Timeline video or audio track is set to receive the video or audio track from the source
clip. It is possible to target no Timeline track for either video or audio. For example, if you build
a rough cut of a music video and the only audio you want to use is a music clip separate from
any of your video clips, you may want to target no audio tracks so that your program receives
no audio from any source video clip. In this example, no audio is added to the program
regardless of how you set the Take icons for the source, and the same is true for targeting video
tracks.
•
For predictable results, watch out for cases where the target tracks don’t make sense
compared to the settings for the source video and audio. For example, if you turn on Take Video
but turn off Take Audio for the source clip, but Timeline tracks are targeted for both video and
audio, the video goes to the target video track as expected, but the source clip audio duration
is inserted in the target audio track as blank space. This is because targeting a track always adds
the duration of the source clip even if the corresponding source track (audio or video) is not
available to the target. If you don’t want the blank audio, specify no target audio tracks.
