The Avidemux is a freeware that is powerful video-editing software. The video-editing software implements various codecs and is multithreaded to work as a standalone program for performing different multimedia functionalities.
Some of the functionalities this software can perform are: transcoding a video file into various standard formats; multiplexing various audio formats into the video file or inserting the audio files by using the built-in codec files, such as libavcodec; demultiplexing audio format or extracting the audio files from the video file by using the built-in codec file, such as libavcodec.
Additionally, the software is capable of automating and processing the video files such as cutting, filtering, and encoding by using the in-built project file system, creating job queues, and using the advanced scripting capability provided in both the Command Line Interface (CLI) and Graphical User Interface (GUI). The software provides filtering capability to enhance the video visual effects and allows the user to configure files using the non-project file system for video editing. By using the non-project file system the configured files can be stored and processed in a simple format.
With a simple and easy-to- use user interface, along with a list of video editing features, the software is considered to be one of the most idealistic programs for basic video editing.
Avidemux is a simple tool for simple video processing tasks. The keyword here is simple: it does not offer tools like a timeline, multitrack editing, you cannot freely move or splice audio and video clips from various sources. However, Avidemux allows you to do elementary things in a very straightforward way.
