Creating color bars and a 1-kHz tone
You can create a one-second clip containing color bars and a 1-kHz tone, as a reference for
calibrating video and audio equipment.
Some audio workflows must be calibrated at a specific tone level. The default level of the
1-kHz tone is 012 dB referenced to 0 dBfs. You can customize the tone level to match your
audio workflow by choosing Clip > Audio Options > Audio Gain with a clip selected. If you
select the bars and tone clip in the Project window, you set the default gain level for new
clip instances. If you select a clip in the Timeline window, you change the level for that clip
instance only.
To create color bars and a 1-kHz tone:
In the Project window, click the New Item button
and choose Bars and Tone from the menu that appears.
Creating black video
Empty areas of a track appear black if no other visible clip areas are present on underlying
video tracks. If necessary, you can also create clips of opaque black video for use anywhere
in a sequence. A black video clip is a still image at the project frame size, with a five-second
duration. To create a clip of a different color, use a color matte (see
on page 233).
To create black video:
In the Project window, click the New Item button
and choose Black Video from the menu that appears.
Using offline files
An offline file is a placeholder for a source file that isn't currently available on disk. Offline
files remember information about the missing source files they represent, and they give
you flexibility when actual files are not available. If an offline file appears in the timeline, a
"Media Offline" message appears in the Program view and in the track.
When you use the Capture window to log clips from a tape, Adobe Premiere Pro automat-
ically creates offline files containing the exact information required to capture the clips
later (see "Logging clips as offline files for batch capture" on page
offline files manually. Use offline files in situations such as the following:
Clips are logged but not yet captured. Because offline files behave like captured clips,
•
you can organize the logged, offline files in the Project window and even lay out
sequences in the Timeline window before the offline clips are actually captured. When
the offline files are captured (or located, if they were captured but missing), they
replace the corresponding offline files.
You want to capture logged clips using device control or batch capture. In Adobe
•
Premiere Pro, a batch-capture list is a set of offline clips; selecting specific offline clips
sets them up for batch capture (see
You want to recapture clips used in the project. This requires making the online clips

offline by using the Project > Unlink Media command (see
