What is Avidemux?
Avidemux is useful when a video needs a shorter cut, a different size or a different encoding. Mark a section with the A and B controls to save an excerpt or remove unwanted footage. The editor supports formats including AVI, MP4, ASF and DVD-compatible MPEG, with separate choices for video encoding, audio encoding and the output container.
For a straightforward cut, Copy mode can preserve the existing streams without re-encoding them. Cut positions still matter: compressed video depends on keyframes, so an arbitrary frame is not always a usable starting point in Copy mode. Choose an encoder when you need a precise cut that Copy mode cannot handle. Cropping, resizing and deinterlacing also require re-encoding; selecting a filter does not make it apply to copied video. Projects, the job queue and scripting help repeat processing tasks.
The linked package is Avidemux 2.8.1 Win64/VC++, supplied as an EXE installer through the publisher-linked SourceForge mirror. It is a 64-bit Windows package, not a portable archive or a 32-bit installer. The official download page does not specify a minimum Windows release. It also advises disabling OpenGL in Preferences if the application crashes after loading a video.
What it offers
- Use A and B markers to select an excerpt to save or a section to remove.
- Work with AVI, MP4, ASF and DVD-compatible MPEG files using supported codecs.

Good to know
- Copy-mode cuts must respect keyframe dependencies; precise cuts away from suitable keyframes may require re-encoding.
- Video filters do not apply in Copy mode. Select a video encoder to use them.
