+
+It can be useful to have visual reference points on the timeline to help you position edits relative to other tracks. For example in manual synchronization of audio and video. You can set two points on the timeline with In/Out points or by selecting a range in Cut and Paste mode. Now we use \texttt{Settings $\rightarrow$ Loop Playback} (Shift - L) to make two vertical green lines appear at the edges of the selection. Originally this function is used to limit the playback within this range, but we can take advantage of the fact that the green lines remain even when we move the insertion point or delete the In/Out points or deselect the range. So they can be used as a visual reference when we want to move the edits precisely. To delete these guides press \textit{Shift-L} again.

\subsection{Compositor Controls}%

\label{ssub:output_size}
\index{temporary}
-\CGG{}'s compositing routines use a \textit{temporary} which is a single frame of video in
-memory where graphics processing takes place. The size of the temporary and of the output in
-the compositing pipeline are different and vary for any particular frame. Effects are processed in
-the temporary and as such are affected by the temporary size. In the case of the camera, its
-viewport is the temporary size. However, projectors are rendered to the output and so are affected
-by the output size. When the temporary is smaller than the output, the temporary will have blank
-borders around the region in the output. When the temporary is larger than the output, it will be
-cropped.
+\CGG{}'s compositing routines use a \textit{temporary} which is a single frame of video in memory where graphics processing takes place. By default the size of the temporary is that of the project ($W \times H$), i.e., the output size. But if the tracks on the timeline have various sizes different from those of the project, then the temporary will take the size of the active track (viewport = green border). We can also change the size of the viewport using the Camera tool, as well as pans and zooms the temporary displayed in it. Effects are processed in the temporary and as such are affected by the temporary size. In the case of the camera, its viewport is the temporary size. The size of the temporary and of the output in the compositing pipeline can be different and vary for any particular frame. However, projectors are rendered to the output and so are affected by the output size. The temporary is the basis on which the Projector tool acts to display the canvas on the Compositor window. The canvas always has the size of the project, although with the projector we can make pans and resizes of the red border inside it. When the temporary is smaller than the output, the temporary will have blank borders around the region in the output. When the temporary is larger than the output, it will be cropped.
\subsubsection*{Track and Output size}%
\label{ssub:track_size}
a video asset and choosing \texttt{Match $\rightarrow$ Match project size}. When you \emph{Match project size}, you
are conforming the output to the asset. To change the size and aspect ratio of the output (Projector) we have to change the whole project, which will alter all the tracks in the timeline. Once you have set the output size in 1 of these 3 ways,
any newly created tracks will conform to the specified output size. When rendering, the project's
-output size is the final video track size where the temporary pipeline is rendered into.
+output size is the final video track size where the temporary pipeline is rendered into.
+
+To clarify, let's take an example.
+
+If we load a media (M) into Resources and adjust the size of the project to the size of M, we will get the canvas size of the media $W_{M} \times H_{M}$). We can see in the Set Format window that the project's default values ($W \times H$) have changed to those of M ($W_{M} \times H_{M}$). The tracks on the timeline can have different sizes, but what we will see on the canvas, that is, in the Compositor window, is always the output size i.e. the size of the project. Tracks with smaller sizes will be seen with black bands; tracks with larger sizes will be cropped. Each track has its own size but we will see it inserted in the output size. If we change the output size the tracks will not change, remaining in their original size. We can only change the size of the tracks by manually acting on each one in the ways seen before. Finally, if we create a new track in a project of size $W \times H$, it will assume the size of the project automatically.
\subsubsection*{Aspect Ratio (Theory)}%
\label{ssub:aspect_ratio_theory}
\textit{SAR}= Storage Aspect Ratio (i.e media file aspect ratio)
+In practice, there can be a problem with anamorphic format rendering as desired because it does
+not use square pixels. So, for example, FFV1 format in the mkv container will ignore the DAR
+(Display Aspect Ratio). You can check if your media is anamorphic format using the \textit{Mediainfo}
+program. If the Width/Height is 720/576 (=1.25) and DAR is 16/9 (=1.777) then you have non-square
+pixels. SAR (Storage Aspect Ratio) is different from DAR and you have to use a workaround as
+described at the "Cinelerra for Grandma" site by Raffaella Traniello:
+{\small\url{http://www.g-raffa.eu/Cinelerra/HOWTO/anamorphic.html}} .

few steps you can create a single simple mask without having to understand every possible parameter.
