+
+To build a version that can handle 8 bit, or 10 bit, or 12 bit videos,
+a patch is provided in the \texttt{thirdparty} subdirectory that needs
+to be applied to do so. Be aware that the compile may take more time
+and seems to be about twice as long. To apply the required patch:
+
+\begin{lstlisting}[style=sh]
+cd /path/to/cinelerra-5.1/thirdparty
+patch < compile_multibit_X265.txt
+mv x265_3.5.patch* src/.
+\end{lstlisting}
+Render formats \textit{h265-10bit} and \textit{h265-12bit} have been provided and will
+be operational after the applied patch is compiled in.
