Match a frame with its source
While editing in a Timeline panel, you can find the source frame for any frame in a sequence clip and display it in the
Source Monitor. Also, you can find the source frame for any frame in a nested sequence, display it in the Source
Monitor, and jump to its location in the source sequence.
1
Click the header of the track where the sequence clip is located, to target the track.
If more than one track is targeted, Premiere Pro will match the frame in the highest targeted track.
2
In a Timeline panel, position the current-time indicator over the desired frame in a clip.
Note: If the source clip for the frame in the sequence clip is already open in the Source Monitor or listed in the Source
menu, the Source Monitor will display the last frame you viewed in the clip. To match the frame, close the clip in the
Source Monitor before typing the Match Frame or Reveal Nested Sequence keyboard shortcut.
3
Do one of the following:
•
For a clip in a standard sequence, type the keyboard shortcut for Match Frame, M by default.
•
For a clip in a nested sequence, type the keyboard shortcut for Reveal Nested Sequence, Shift-T by default.
Waveform monitors and vectorscope
About the waveform monitors and vectorscope
Premiere Pro has a vectorscope and waveform monitors (YC Waveform, YCbCr Parade, and RGB Parade) to help you
output a video program that meets broadcast standards and also assist you in making adjustments based on aesthetic
considerations, such as color corrections.
For decades, video production and duplication facilities have used waveform monitors and vectorscopes to accurately
evaluate video levels—specifically, color and brightness.
A vectorscope measures the chrominance (color components) of a video signal, including hue and saturation. A
vectorscope maps a video’s color information onto a circular chart.
The traditional waveform monitor is useful in measuring the brightness, or luminance component, of a video signal.
In Premiere Pro, the waveform monitors can also display chrominance information. The waveform monitor works
something like a graph. The horizontal axis of the graph corresponds to the video image from left to right. Vertically,
the waveform displays the luminance levels, and optionally, the chrominance levels.

View a scope
You can view a vectorscope, YC waveform, YCbCr Parade, and an RGB Parade scope either individually or grouped
in the Reference Monitor, Program Monitor, or Source Monitor.
1
Depending on whether you want to view a scope for a master clip or sequence clip, do one of the following:
•
Double-click the clip in the Project panel.
•
In a Timeline panel, position the current-time indicator in the sequence you want.
2
(Optional) Choose Reference Monitor from the Window menu if you selected a clip in a Timeline panel.
