WinFF is a GUI frontend and batch parser for the command-line multimedia tool FFmpeg. WinFF works by making a batch file that runs in the command-line, designed to launch the command-line tool with given settings from a preset. To query several files, WinFF adds launch functions in the same batch file to allow a seamless transition to the next conversion. Because of the vast format support of the command-line tool itself, this program supports any of its formats as a result (however, the included executable may not be up-to-date, so the user may need to download the Zeranoe builds to take advantage of the latest features).
WinFF is written in Free Pascal and Lazarus, published under the GNU General Public License.
