WinFF is an FFmpeg based GUI for Windows. At its core is the FFmpeg program itself, designed for command-line-based processing of video and audio files.It is widely used for format transcoding, basic editing (trimming and concatenation), video scaling, video post. FFmpeg is a free and open-source software project consisting of a large suite of libraries and programs for handling video, audio, and other multimedia files and streams.
Installing the 64-bit FFmpeg library will not overwrite or delete your 32-bit. This means that if you are a user of previous Audacity versions on Mac and had installed the optional FFmpeg library then you must now install the 64-bit versions of the FFmpeg library, otherwise your imports and exports that depend upon FFmpeg will no longer work. Audacity 2.3.1 on Mac is now a 64-bit application.
