Machete is a user-friendly, lossless video editor with support for a range of file formats, including AVI, WMV, MP4, and more. With this software, users can conveniently extract and save audio and video streams as separate files, add, or replace audio streams within video files.

Machete offers several additional functions, such as the ability to extract and save video and audio streams as separate files, the ability to add/replace audio stream in AVI, MKV, MP4, MOV, WMV and FLV files, and the ability to save a video frame as a bitmap (.bmp) file. You can also view and edit file tags (metadata) associated with any of the supported media formats.
The software currently supports several video and audio codecs for different file types, including AVI, WMV, MKV, WebM, MP4, 3GP, MOV, WMA, MP3, WAV, and FLV files. The key feature of Machete is that editing a video file is performed without re-encoding (so-called lossless editing). This saves time and prevents loss of video or audio quality. Additionally, it means that you don't need a powerful and expensive computer to edit your video material.
Machete does not require installation of any special codecs for multimedia editing in addition to regular decoders that are needed for video viewing and audio playback. You don't need any special skills or advanced knowledge to edit video with Machete. This software also retains the original format of the video file after it is edited and saved.
Finally, Machete will continue to add support for more video formats in future versions. Overall, Machete is an excellent video editing software that makes simple cutting, copying, and editing a breeze.
