Avidemux 2.7.3

Avidemux is a freeware, open-source video editor designed for multi-purpose video editing, converting, simple cutting, resizing, filtering and encoding tasks.

It supports many file types, including AVI, MP4, Matroska, MPEG-2, H.264 and H.265. It does not yet, or only partially supports modern open formats, like Opus, WebM, VP8, VP9 and AV1. Tasks can be automated using projects, job queue and powerful scripting capabilities.

Avidemux enables you to edit most video files by your requirements to make them play on any selected device. Multi-threading is supported! The graphical user interface of Avidemux looks pretty similar to VirtualDub. The most features known from VirtualDub are available too and natively supports a great file types, such as AVI, MKV, MPEG, VOB, MP4, TS, ASF, OGM and FLV.

Avidemux cannot open raw MPEG streams. Instead, it can open indexed MPEG streams. The index is a text file containing navigation information. It is needed to allow frame accuracy.
As for MPEG streams, a NuppelVideo file has no internal index. Avidemux will rebuild it automatically upon loading (that could take some minutes).

Avidemux can also open a stream of uncompressed BMP files (RGB) or a set of JPEG files or a set of PNG files. The latest version of Avidemux can usually decode the WMV/ASF containers, there are occasionally some files that still have problems with opening or playing. If you have that problem, then you can try to place the WMV contents into an AVI container.


Multithreading has been implemented in the following areas of Avidemux (some partially through libavcodec):

  • Encoding
    • MPEG-1 and MPEG-2 (using libavcodec)
    • MPEG-4 Part 2 SP/ASP (using libavcodec or Xvid)
      • Earlier versions of Xvid are not compatible with this feature.
    • H.264/MPEG-4 Part 10 AVC (using x264)
    • H.265/HEVC (using x265)
  • Decoding
    • MPEG-1 and MPEG-2 (using libavcodec)
    • MPEG-4 Part 2 SP/ASP (using libavcodec)

Changes in Avidemux 2.7.2:

  • Win64 version are now compiled with Visual C++, it should help stability wise
  • New Demuxer:Native AviSynth demuxer (MSVC++ 64 bits Windows builds only), 64bits avisynth only !
  • New Demuxer:VapourSynth demuxer to directly load .vpy scripts (MSVC++, macOS with Homebrew, custom Linux builds), 64bits vapoursynth only on win64!

    I can't belive they are still updating this program seeing that avi is no longer the main container for video. In fact it will no longer be of any use in the future. It has been replaced with other formats such as mpeg4, mp4, mkv, etc. I'll take this one though because my main video files are avi and my dvd players only play avi so this is good news. Thanks for the update.
