More specific information on which plugins need to use \textit{Proxy 1:1}. is provided here next. If the keyframe data uses coordinate data that is absolute, then the Factor scale = 1 should be used. If the data is normalized (like always $0-100\%$) then the proxy can be done with downsize (i.e. classic \textit{Proxy}). The session geometry format, shown in \texttt{Settings $\rightarrow$ Format} as $width \times height$, is changed if scale factor $\neq$ 1 is used to cause all of the data to be in the reduced format. If this affects the plugin operation, then \textit{Proxy 1:1} should be used. Examples of plugins that need the \textit{Proxy 1:1} are: Title, AutoScale, Scale, ScaleRatio, and Translate. Most others are safe to use with downsize.

+Next are some examples of tested and working configurations that maintain the alpha channel:

+ Quality: -1
+ Pixels: rgba (or rgba64be)

Instead just use the X to dismiss the warning.

-Workaround cases for the alpha channel not working as intended when using an EDL inserted as a reference
-is described in \ref{sub:nested_clips}.
-
Here is a step by step example of how you can use \textit{File by
Reference}:
\begin{enumerate}
video track which is independent from the redrawing of the audio tracks. The playback is still synchronized.
\end{itemize}
-Workaround cases for the alpha channel not working as intended when using an EDL inserted as a reference
-or when an EDL is nested, is described here.
-
-\paragraph{Case 1 using the Projector on the EDL within a Master Project:} follow these next steps.
-\begin{itemize}
- \item Open your EDL with \textit{Open EDL} by using the middle mouse button on the Nested edit on its track.
- \item In this nested EDL, insert a new Video track below the last video track.
- \item Add the Alpha plugin to the new Video track for the entire length of the nested EDL.
- \item Change the value of the Alpha to 0.00.
- \item Close the EDL.
-\end{itemize} This solves the alpha channel not working as expected and the Master Project now looks correct.
-
-\paragraph{Case 2 using FadeIn/Out with autos:}
-In the Master Project for the Videeo track containing the nested EDL, in its Patchbay change
-the \textit{Overlay Mode} from \textit{Normal} to \textit{PorterDuff->SrcOver}.
