Also note that 'Auto make Movie' and 'Delete frames after encoding' are UN-Checked.  You have a lot of options that are check boxes.  If you wanted to you could render the frames keeping them AND also make a movie.  Also if you render the frames and go into some of them and edit them to add or delete some part of the that frame then you could just press the 'Encode Existing Images' and it will make a movie based on the frames already rendered.  The old way if you wanted to have two different formats of the movie meant rendering the scene twice.  Now you can make a movie of each format without re-rendering.
