\item[Smooth:] serves to make the graph more homogeneous, improving its visualization.
- \item[Refresh on Stop ON:] scopes are updated when you stop playback at a given location. Instead, they are locked at the start position while you playback (by dragging the cursor or using the Transport buttuns). This saves system resources and makes playback smoother.
- \item[Refresh on Stop OFF:] the display of the scopes is synchronized with the playback. Every variation of the graphs is in realtime. There may be some decrease in fps during playback.
- \item[Refresh on Release:] This works for the Viewer and Compositor windows. Scopes are not updated
-during playback. The update occurs only when you stop playback, that is at the final position (either by
-dragging the cursor or using the Transport buttons). When in the timeline, if you drag on the TimeBar or
-reposition in the TimeBar in either Drag and Drop or Cut and Paste mode, the release of the button also will
-update the Scopes. This saves system resources and makes playback smoother. Because there is no update when
-playing in the main window, you can still easily get a videoscope update simply by moving the mouse to the
-Compositor and a single click there will update the scopes without changing the frame (as long as Click to
-Play is not enabled).

The lower section, called \textit{VectorWheel Grids}, it is only active when VectorWheel is set up in Scopes pull-down and contains four entries (figure~\ref{fig:videoscope06}):

\item[None:] It only shows the colour wheel, without any superimposed graticula.
\item[IQ:] Show shows only I-Line and Q-Line.

You can create custom grids. These are raster .png images of adequate resolution and must be put in:
\item create a temporary directory on your computer
\item \texttt{cd} that-directory
\item \texttt{tar -xf} location-of-the-tarball-you-downloaded
- \item \texttt{cp plugins/*obj.plugin <see below for your location>/.} (note the period on the end)
+ \item \texttt{cp plugins/opencv/*obj.plugin <see below for your location>/.} (note the period on the end)
\item Start \CGG{} and look for the six plugins in Video Effects
\item To reverse this, simply delete the six plugin files (for example:
Location for some System installs is:
-\hspace{4em}\texttt{/usr/lib/cin/plugins/} (most ubuntu distros)\\
+\hspace{4em}\texttt{/usr/lib/cin/plugins/} (most ubuntu distros)
