Layout Options in Video Scopes Tabs
You can choose which scopes and which video source appear in each Video Scopes tab
by using the following controls:
 Layout: Use this pop-up menu to choose one of eight different combinations of
single or multiple scopes for display in the Video Scopes tab. If you choose a single
scope from the list, it takes up the entire space of the Video Scopes tab, making it
easier to see. If you choose one of the multiple-scope layouts, all displayed scopes
appear at a reduced size so that they fit into the Video Scopes tab at the same time.
 View: Use the options in the View pop-up menu to select which frame is being
analyzed in the Video Scopes tab. Choose Current Frame to analyze the current frame
at the position of the playhead in the Canvas. Other options allow you to select
various edit points that are adjacent to the playhead in the currently selected
sequence. You can also choose the frame at the position of the playhead in the
Viewer. Choosing None disables the scopes altogether.
One way to use this feature is to pair up separate windows with Video Scopes tabs
and Frame Viewer tabs, with each pair of windows set to display different edit points
in your sequence for purposes of comparison.
Learning to Read the Waveform Monitor
The Waveform Monitor shows you the relative levels of luma and chroma saturation
in the clip currently being examined. These values are displayed from left to right,
mirroring the relative distribution of these levels from the left to the right of the image
in the frame. Spikes and dips in the displayed waveforms correspond to hot spots and
dark areas in your picture.
