+The \textit{Track size} is used to define the temporary size with each track having a different size (viewports). It also serves to conform the input media to a chosen format (aspect ratio). So each track can have a different format (viewport).

the track to any size. Or select \emph{Match output size} to make the track the same size as the

+a track in regards to the final output. This feature means you can create visual effects such as different aspect ratios, adjust split screens, zooms, and pans in the compositor.
The \textit{Output size} can be set in \texttt{File $\rightarrow$ New} when creating a new project,
or by using \texttt{Settings $\rightarrow$ Format}, or in the Resources window with RMB click on

+\subsubsection*{Aspect Ratio (Theory)}%
+\label{ssub:aspect_ratio_theory}
+
+The aspect ratio is the ratio of the sides of the frame (\textit{Width} and \textit{Height}). For example, classically broadcast TV was 4:3 (= 1.33), whereas today it has changed to 16:9 (= 1.85); in cinema we use the 35 mm aspect ratio of 1.37 (Academic aperture), but even more so the super 35 mm (2.35). There are also anamorphic formats, i.e. that have no square pixels, like Cinemascope (2.35). The projection must be \textit{normalized} to have an undistorted view.
+
+
+From the film or digital sensors of the cameras, we can extract any frame size we want. We are talking about \textit{viewports}, which we will examine shortly. Also important is the output of the film that will be rendered, because it is what we will see at the cinema, or on TV, or on the monitor of the PC, tablet or smartphone. Referring to figure~\ref{fig:temporary-01}, you can see these two possibilities: with the Camera you choose the size and aspect ratio of the source file (regardless of the original size); while with the Projector you choose the size and aspect ratio of the output.
+
+The following formula is used to vary the aspect ratio:
+
+\qquad $\frac{W}{H} =$ aspect ratio ($\frac{pixels}{pixels}$)
+
+For example to obtain an aspect ratio of Super 35 mmm (2.35) starting from a FullHD file (1920x1080) whose base extension (1920) we want to keep:
+
+\qquad $\frac{1920}{H} = 2.35$
+
+from which: $H = 817$ pixels
+
+\CGG{} allows you to vary the input and output aspect ratio in the ways indicated in the previous section: by varying the pixels of the sides or by setting a multiplication coefficient.
+
+In \texttt{Settings $\rightarrow$ Format} there is the additional possibility to vary the shape of the pixels from 1:1 (square) to handle anamorphic formats. In such cases we use:
+
+\qquad $PAR=\frac{DAR}{SAR}$
+
+where:
+
+\textit{DAR}= Display Aspect Ratio
+
+\textit{PAR}= Pixel Aspect Ratio (1 or 1:1 is square)
+
+\textit{SAR}= Storage Aspect Ratio (i.e media file aspect ratio)
+
\subsection{Camera and Projector}%
\label{sub:camera_and_projector}
\subsubsection*{The Viewport}%
\label{ssub:viewport}
-The \textit{viewport} is a window on the camera that frames the area of source video. The size of
-the current track is used for the initial size of the viewport. A smaller viewport, for example
-($640\times480$), captures a smaller area; whereas a larger viewport of ($800\times600$) captures
-a larger area. If the captured area is larger than the source video, the empty spaces will be
-automatically filled with blanks. After the viewport is defined, the camera needs to be placed
-right above the area of interest in the source video. Operations to control the location of the
-camera are as follows:

A smaller viewport, for example ($640\times480$), captures a smaller area; whereas a larger viewport of ($800\times600$) captures a larger area. If the captured area is larger than the source video, the empty spaces will be automatically filled with blanks. To change the size and aspect ratio of the viewport (Camera) of a single track, right-click on the track in the timeline and choose Resize Track. Here we can vary the height and base of the viewport in pixels or choose the multiplication coefficient for each side (Scale). With OK we will see the change in the Compositor window with the new dimensions reflected in the green box. We can have different size viewports for each video track on the timeline. To go back, reset the viewport to the original value. After the viewport is defined, the camera needs to be placed right above the area of interest in the source video. Operations to control the location of the camera are as follows:
\begin{enumerate}
\item In the compositor window you should see the selected track.
Most operations in the Compositor window have a tool window which is enabled by activating the question mark icon (figure~\ref{fig:camera_tool}).

+ \label{fig:vieweraudio}
+\end{figure}
+
+You can also use the Viewer to listen to media that consists only of Audio. This is a quick way
+to listen to the audio to see if it is what you would like to add to a timeline audio track for
+your project. To do this, you simply drag the audio file from the Resources window in the same
+manner as a video file. The viewer was designed to "view" images rather than play audio so in order
+to make it obvious that audio media is loaded to the viewer, a waveform is displayed that is the
+same waveform as shown in the Resources window thumbnail when in the \textit{Display Icons} mode.
+This waveform only represents the first 5 seconds of the media and will not change or move while
+playing in the Viewer window. But you can play the entire piece of media in the window
+and as you do so, you see the play cursor line move along and the timestamp reflect the actual
+position. You can also create clips. The entire waveform can only be seen on an actual audio track
+on the timeline. An example of what this looks like is shown in figure~\ref{fig:vieweraudio}.

\section{Options in both the Compositor and Viewer Windows}%
\label{sec:options_in_both_the_compositor_and_viewer_windows}
The asset \emph{Info} window also can be used to display detailed information about the selected/highlighted media file -- available for any loaded media of type mpeg or ffmpeg.
This is extremely helpful in determining what type of media it is, size, resolution, format, and type/number of audio streams. It is especially useful for multiple program streams. You can have the info window popped on several of your assets simultaneously.
+\textit{Detail} opens an additional window with more information.
+
+\textit{Sample rate} and \textit{Frame rate} allows you to impose a different sampling or Fps of the audio and video assets.
+
+Another option is \textit{Resize} button, which allows you to change the sides (in pixels) of the frame of the asset.

\textit{Asset's interlacing} is the type of interlacing the asset has: If the file is (H)DV type, recognition and configuration is done automatically. All other media types will be set unknown. So we have to manually set the interlacing \protect\footnote{From Igor ubuntu's mail}.
Figure~\ref{fig:info_asset_details} shows the \textit{Detail} box to click on the left side and a simple, typical output in the Asset Detail window on the right side. Also, note the highlighted media in the Resources window.

The levels window displays the output audio levels after all mixing is done.
The visible range of the sound level meters is configurable in \texttt{Settings $\rightarrow$ Preferences, Interface tab} under the Operations section.

Sound level meters can be toggled in the viewer and compositor windows with the show meters button.
They also appear in the patchbay when the track is expanded and in the recording monitor when audio is being recorded.
In the patchbay they are the sound levels for each track after all effects are processed and before down-mixing for the output.
Most of the time, audio levels have numerical markings in dB but in the patchbay there is not enough room.

The sound level is color coded as an extra means of determining the sound level.
Even without numerical markings, the sound level color can distinguish between several ranges and overload.
Look at the color codings in a meter with numerical markings to see what colors correspond to what sound level.
