-The proxy videos will be added to your assets in a separate Proxy folder \index{proxy!folder}, and the video track edits will use the proxies.
-The assets in both the Media folder and Proxy folder will look proxied when dragged to the Viewer although the scale may be different.
-Proxy downsizing renders all loaded tracks, but only work on the $1^{st}$ video layer of any multi-layer media. Rendered proxy media is saved in the same directory as the original media.
-However, if you proxy your session, the clips do not get proxied to the Proxy folder, but if you Drag and Drop the clip from the Clip folder to the Viewer or the Timeline, you will see that it too is proxied.
-As usual, you can delete proxy files from the project or disk in the Resources window if you no longer want to retain them.
-And you can save your project either as proxied or not.
+You will know that Proxy mode is enabled because:
+\begin{itemize}
+ \item A white colored \textbf{P} meaning \textit{Proxy}, or a white colored \textbf{S} meaning \textit{Proxy Scaled} icon is shown in the upper right corner of the main window to the left of the FF icon. If using the Cakewalk or Neophyte theme it will be a \textbf{Ps} icon.
+ \item The Proxy folder in the Resources window has been populated with the names and/or icons of the proxy media.
+ \item The track title bar in the timeline will have the name of the proxy file instead of the original name. So if the video filename is \texttt{VID\_20221012.mp4}, the Proxy Scale Factor is $\frac{1}{4}$, and the Proxy container is mov, then the proxy name will be \texttt{VID\_20221012.proxy4-mp4.mov}.
+\end{itemize}
+
+The Proxy icon is a toggle button so that you just click on the icon to change modes. Or it can be toggled using the \texttt{Ctrl+R} shortcut.

+
+When you disable Proxy using the toggle button for Proxy, or its shortcut (\texttt{Ctrl+R}), in the Proxy Settings window you will see the \texttt{Scale Factor = 1}, but if you look at the Active Scale and the State, you can understand what your setting is.
+Proxy can have three possible States: Off, Active, Disabled. The difference between Off and Disabled is that Disabled means you have set the Proxy and it is temporarily switched off (and you can see the icon in the upper right corner of the main window); you can enable proxy by just clicking on the icon, so the State will then be changed from Disabled to Active.

+\subsection{How Rescaled to project size (FFMPEG only) works}%
+\label{sub:rescaled_project_size_works}
+
+\begin{itemize}
+ \item When \texttt{Rescaled to project size (FFMPEG only)} is checked, the size of the video data to be computed will always be the same as the Project Format. The size of your video is scaled down to the Scale factor BUT then it is rescaled up to the Project Format. For example, your Project Format is 1920x1080 and Proxy's Scale factor is $\frac{1}{4}$, then your videos ($1920x1080$) will be scaled down to 480x270 and then up-scaled to $1920x1080$. All the Effects/Plugins work correctly because the original resolution/geometry/size is not changed. For an old computer, this option is not recommended.
+ \item When \texttt{Rescaled to project size (FFMPEG only)} is UNchecked, the size of the video data to be computed will be reduced to the Scale factor. The size of your video is scaled down to the Scale factor. For example, your Project Format is 1920x1080 and Proxy's Scale factor is $\frac{1}{4}$, then your videos ($1920x1080$) will be scaled down to $480x270$. It works as if the Project Format were $480x270$ (and really it works). If you take a look at \texttt{Settings $\rightarrow$ Format...} when Proxy is enabled (Active), you can see that the Width and Height are changed according to the Scale factor; you absolutely must NOT change these values! The good thing is that your computer will be faster. The bad thing is that some Effects/Plugins do not work as expected because they use pixel units. Examples are \texttt{Title} and \texttt{Blur} plugins. A workaround is needed for that.
