-There is also a convenient \textit{Beep on done volume} dial included so that you can work on other tasks until there is an audible notify of completion. The default volume is set to 0 for no audible notify.

-A good choice for proxy settings with 1080p source video is:
-
-\begin{lstlisting}[language=bash,numbers=none]
-Scale Factor: 1/4
-Use Scaler: unchecked
-File Format: FFMPEG - mpeg
-Video Preset:
-Compression: mpeg.mpeg
-Bitrate: 1800000
-Quality: -1
-Pixels: yuv420p
-\end{lstlisting}
-
-If you get errors for some videos, such as those with strange variable bit rate or some types of files made on a smartphone, a usually reliable alternative is to change the following parameters:
-
-\begin{lstlisting}[language=bash,numbers=none]
-File Format: FFMPEG - mov
-Video Preset:
-Compression: mov.mov
-\end{lstlisting}
-
-Or if you want small files with high image quality, a File Format of m2ts is optimal. For example a 1 GB file can be reduced to 50 MB with scale $\frac{1}{2}$.
-
-Checking the \textit{Auto proxy/scale media loads} results in any additional media loads to be automatically proxy scaled. However, single frame media such as PNG or JPEG \textit{stills}, can not be scaled to \textit{stream} media. If this type of media exists, you should \textit{use scaler}.
-
-If you get error messages when creating proxies, check the Video wrench settings. These usually default to values that are expected to work correctly for the \textit{File Format} and codec you selected but they can be changed and may result in errors. If you get an error message of \textit{check\_frame\_rate failed} followed by \textit{Error making proxy} in the popup Errors window, do just that and check the Frame rate value by going to the Resources window, Media folder, and use the right mouse button for the Info option for that specific media in question. You can change the frame rate in this window to a more codec acceptable value. Different codecs may have different legal values.

-More specific information on which plugins need to use scaler is provided here next. If the keyframe data uses coordinate data that is absolute, then the scaler should be used. If the data is normalized (like always $0-100\%$) then the proxy can be done without the scaler. The session geometry format, shown in \texttt{Settings $\rightarrow$ Format} as $width \times height$, is changed if the scaler is not used to cause all of the data to be in the reduced format. If this affects the plugin operation, then scaler should be used. Examples of plugins that need the scaler are: Title, AutoScale, Scale, ScaleRatio, and Translate. Most others are safe to use without scaling.

- This makes its so that you can save your project
-either as proxied or not.
-
-\textbf{Transcode}, an option under the Settings pulldown right next to the Proxy settings option, is a type of full resolution \textbf{1:1 Proxy}.
-The process of transcoding works directly from the resource; it is independent of the timeline.
-All of the loaded asset media will be converted, that is, rendered in the selected format and loaded onto the timeline.
-Menu choices besides the usual File Format and File Type include: \textit{Tag suffix} (to add to media filename), \textit{Remove originals from project}, \textit{Into Nested Proxy directory} (an option to have the file saved here instead of the location of the original media), and \textit{Beep on done} volume.
