+\index{workarounds}
+
+Some workarounds for issues and a few known problems that have not yet been fixed, are described here.
+
+\paragraph{Workaround for access to modifiable text files when using AppImage.} This includes
+such files as FFmpeg video or audio files, fonts that you want to add for usage in the Title
+plugin, icons that you wish to modify, and any other text file for customization.
+To get access, first extract the files from the AppImage, find the files to add, edit, or modify, and then run the extracted binary following the steps shown here.
+\begin{itemize}
+ \item /path-to-appimage/CinGG-20220131-x86\_64.AppImage -{}-appimage-extract
+ \item edit or add the files you want to modify in the \textit{bin} or \textit{lib} subdirecctory
+ \item /path-to-appimage/squashfs-root/usr/bin/cin
+\end{itemize}
+For more detailed information on working with AppImages, see \ref{sub:managing_appimage}.
+
+\paragraph{Workaround for the \textit{alpha channel not working as intended when using an EDL} inserted as a reference or when an EDL is nested.}
+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 MMB (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. The Alpha Plugin may be disabled or left enabled.
+ \item Close the EDL.
+\end{itemize} This solves the alpha channel not working as expected and the Master Project now looks correct.
+
+\paragraph{Workaround for using a transition, like Dissolve, between 2 edits with the plugin Motion51.}
+In this case, the Motion51 plugin and the Dissolve transition are not seen during the transition phase
+and is stopped at the cut point between 2 edits.
+The left edit's plugin should be in effect until the end of that clip and should include the
+dissolve. Instead, there is a jump inside the dissolve, as if the plugin does not exist. There are
+2 possible workarounds. For example, extend the Motion51 plugin to cover both clips rather than
+having a separate plugin for each clip. Or another workaround is to use two tracks and have the
+plugin cover the cut point and use a Fade auto instead of the Dissolve transition.
+
+\paragraph{The Fade auto in certain circumstances produces an unwanted black flash.}
+When you insert an effect on an empty track the fade fades as if it were on a black background;
+it interprets the alpha as black where there is transparency, which is what produces the fade.
+So the problem in the case of text is that the letters appear as a black flash briefly in the first
+few frames, then goes back to transparent, then the fade starts normally with the white color.
+To avoid the unwanted effect produced by the fade over black (because there is no content) leave
+the fade in/out of the effect at 0 and use the fade line to perform the intended results to
+avoid the problem with the alpha channel. The same problem occurs when using transparent PNG
+images with fade video transitions and can be resolved in the same manner.
+However this workaround can be quite tedious and complicated if you want to fade many snippets of text
+and transparent PNGs on the same track, with always the same video transition filter set to the same
+duration.
+
+Just a side note here. Fade in/out in the Title plugin works fine if there is a clip/image above
+the plugin in the same track without an alpha channel but not if there is no clip/image.
+And the Transition effect works fine when there is a transition between two clips/images without
+an alpha channel.
+
+\paragraph{Audio tracks align with no video track, and in working with Mixers.}
+
+The use of \texttt{Open Mixers} always requires the existence of a video track. See \nameref{ssub:but_use_only_first_audio} We cannot act on audio tracks only, for example to align them. A workaround to get the audio tracks aligned would be:
+
+\begin{enumerate}
+ \item You create/open the \textit{Mixer Viewer} with \texttt{Open Mixers} in Resources window for the Videos with Audio. It will create, in the timeline, one Video track and two Audio tracks for each Media (Video/Audio), and its Mixer Viewer.
+ \item Add a new Video track (\texttt{Shift+T} shortcut) and two Audio tracks (\texttt{t} shortcut) for your audio (Left+Right channels?) without video: you are adding an empty Video track because \texttt{Align Mixers} feature needed a video track.
+ \item Move the Video track down until it is on the top of the two Audio
+ tracks.
+ \item Insert your Audio into the two Audio tracks in the usual way.
+ \item Open/Create a Mixer Viewer from \texttt{Menu $\rightarrow$ Window $\rightarrow$ Mixer\dots $\rightarrow$ Mixer Viewer} (\texttt{Shift+M}).
+ \item Assign that Mixer Viewer (a white frame is shown when selected) to the one Video tracks (empty) and two Audio tracks, of the \#2 point, pressing the arrow icons (\texttt{Mixer}) you find on the Patchbay on the left of the Main window. When assigned, you must to see the 3 arrow (for 1video + 2Audio) are pointing up.
+ \item Now, you can use \texttt{Align Mixers} feature as usual. See \nameref{sec:audio_video_sync}
+\end{enumerate}
