Avidemux is a simple video editor that allows you to cut, apply filters, and encode video files.

Sometimes you need to remove some of your videos or split a video into several parts. If you do this in video editing software, you will have to render the cut video, which will take more time than necessary. For example, imagine that you have recorded a gameplay of a game, and this gameplay lasts 1 hour. Now, you want to delete only the first 30 seconds of the video, in which you can see how you have launched the game, etc. Suppose you eliminate these first 30 seconds with a video editing program. In that case, you will have to re-render the 1-hour video, which, if you do not have a very powerful computer, may take several tens of minutes.

To avoid this, you have Avidemux, which will be able to eliminate the first 30 seconds of the video and save the new video without having to render it in such a way that in a few seconds, you will have your new video cut, regardless of how long it is.

The user interface of this software is very simple and is as easy as opening the video you want to edit and selecting the output format of audio and video. If you choose "Copy," the software will not recode the video or audio. You can also choose the video container (avi, mkv, mp4, etc).

At the bottom, some buttons allow you to trim the video. The “A” button marks the cut's start, and the “B” button marks the end of the cut. In such a way that if you save the file (Ctrl+S), a new file will be saved, which will reach from the “A” cut until the “B” cut.

You can also apply video and audio filters in trimming and recording the video files. Some of the video filters that can be applied are: adding black borders, adding a logo, replacing one section with black, dark edges, fade, rotate, see as ASCII code and more.

If the sound is out of sync with the image, you can resynchronize it using the "Move sound" option. Also, you can resample the sound to a greater or lesser frequency.

The program is free and translated into many languages, making it ideal for making simple cut-out editions that could take longer with any other software.
