-There are thousands of options for using ffmpeg. Now it is possible to \textit{view} the available options for a particular video and audio choice by using the \textit{wrench icon} and then clicking on the \textit{view} box. Ffmpeg has to be the selected file format for this feature to be visible. It makes it a lot easier since only the applicable options show up as opposed to everything that ffmpeg can do. These options are just \textit{Hints} and some may be missing due to the way that ffmpeg options are coded --- Cinelerra shows the option data ffmpeg has exposed.
+As an example, instead of reading the entire 264 library
+information, you only have to look at the shown available options.
+Both the video and the audio are browsable. The options visible in
+the \textit{Audio/Video Preset} textbox are the final values which
+are used when rendering once you have checked OK\@. For assistance
+in choosing the options you want, use the view popup to see the
+objects that go with the selected format tool, highlight the option,
+modify the parameter value in the box at the top of the
+\textit{Options} window based on what you want, and then click
+apply. Updated parameter values or new parameters will be appended
+at the bottom. Note that when you highlight an option, a tooltip
+will show up when available in the lower right hand corner which
+describes the option. Also note that the Format and Codec types are
+shown on the top line of the Options window.
