Using Machete, you can quickly and easily remux a selected video file (this is called remuxing process). The resulting file will be stripped of extra information, such as subtitles, unneeded audio streams etc while preserving its original video and audio quality. Through remuxing, you can reduce the size of the file without changing its format.
With Machete, you can add an audio to a video file, or replace an existing audio stream (track) with a new one. Machete adds an audio stream to an entire video file starting at the beginning (from zero (0) position) regardless of any current playback position set within a file. With Machete, you can add up to four audio streams to one file, except in FLV files which cannot contain more than one audio stream.
To edit a video file in Machete: open menu item File-> Open or use Open button to launch Open File dialog and select a required file from the list and press Open. The LED panel will display the type of the opened file (AVI, MKV, MP4, 3GP, MOV, MP3, WAV, FLV, WMV or WMA).
Using Machete, you can quickly and easily split (cut) a multimedia file into two (or several) fragments, cut out unnecessary fragments (for example, commercials) and save a selected fragment as an individual file. In addition, you can join two or more files with exactly the same format. While many popular video joiners allow the adding of files only to the beginning or to the end of a current file, with Machete you can insert a new file at any position within an opened file.
With Machete, you can quickly and easily extract an audio (or video) from a video file and save it as a separate file. Since all editing operations in Machete are lossless (performed without re-encoding), your audio (or video) stream will be extracted and saved without any quality loss.
