Avidemux is a program for compressing and trimming video and audio, as well as adding effects. This open source application is capable of encoding videos in the most widespread codecs, including MPEG-2 (with libavcodec), MPEG-4/H.264 (with x264), and HEVC/H.265 (with x265). Thanks to the use of these codecs, you can reduce the size of any video. In the case of audio, you can compress to all kinds of formats, such as AAC, AC3, and MP3, among many others.
Among the most basic video adjustments, you can trim content to remove unwanted parts, as well as correct the synchronization between video and audio.
In addition to compressing videos using a more efficient codec, Avidemux also allows you to use filters to modify the content. For example, you can add logos, change the frames per second, crop, recompress to fit a specific size, stabilize the image, add subtitles, reduce noise, add detail, apply a color profile using LUT, and much more. Plus, with the artistic filters available on Avidemux, you can make a video look like it was recorded on VHS or replace a green chroma key with the image you want in the background.
If you're looking for a free and easy-to-use video compression and editing program, don't hesitate to download Avidemux.

Cut and paste without re-encoding the video. This allows maintaining the original quality and is extremely fast. Just for that, it deserves 5 stars.
