Avidemux for Windows

Avidemux for Windows: Cut, Encode, and Filter Without a Subscription

Avidemux is a free, open source licensed video editor built for cutting, encoding, and filtering clips across popular formats — and this article explains exactly what it can and cannot do on a Windows desktop or laptop.

Avidemux for windows handles practical work that heavier non-linear editors (NLEs) make unnecessarily complicated. Trim an MP4, remux footage into MKV, apply a filter chain before export, swap an audio track. No subscription. No watermark on output. No bundle. No tracker.

It is not a timeline-based NLE. Video is processed linearly — source in, output out — which is the right architecture for single-track encode jobs and makes it one of the more focused pieces of desktop video editing software available without a price tag.

What Avidemux Supports on Windows

Formats and Codecs

The editor reads and writes MP4, AVI, MKV, MOV, and MPEG containers. Output codec options include H.264, H.265, AAC, and MP3, among others. Frame rate and bitrate are configurable per job. For anyone running Windows 10 or Windows 11 on a 64 bit PC, all these options are available out of the box without hunting down separate codec packs.

Core Features

• Frame-accurate video cutting and video trimming without re-encoding
• Avidemux video encoding via built-in codec libraries — H.264 and H.265 output included
• Filter chain for applying effects (sharpening, color correction, resizing, deinterlacing) before the final render
• Audio synchronization and volume normalization on the audio track
• Job queue for batch processing — line up multiple encode tasks and walk away
• Subtitle support and scene detection tools
• Auto-copy mode — passes the video stream through untouched when no re-encoding is needed, preserving original bitrate exactly

No multi-track timeline. No transitions. No color grading LUT pipeline. If those are requirements, look at DaVinci Resolve or Kdenlive instead.

How to Cut and Save Without Re-Encoding

This is the most common use case for this tool on Windows, and the answer is faster than most users expect.

1. Open your source file: File > Open

2. Set Video codec to Copy under Video > Copy

3. Set Audio codec to Copy under Audio > Copy

4. Mark your cut-in point with the A key, cut-out with the B key

5. Export: File > Save

With auto-copy active, Avidemux passes the H.264 or H.265 stream through untouched. Encode time drops to seconds. Bitrate and quality are identical to the source. This is the defining feature that makes it genuinely useful as an open source video cutter for archivists and anyone handling large files.

Batch Encoding With the Jobs Queue

Setting Up Multiple Outputs

File > Manage Jobs lets you queue the same source file for multiple output configurations — for example, an H.264 MP4 for web and an MKV copy for archive — without re-opening the source. Add each configuration as a separate job entry, then run the queue.

This is where Avidemux for windows pulls ahead of basic video filtering software free alternatives that lack any queue system at all.

Getting the Installer

The installer for Windows 10, Windows 11, and Windows 7 (32-bit and 64-bit) is covered in the Avidemux Windows installer and setup guide. If a portable build that runs without installation suits your workflow better, that option is detailed in the Avidemux portable version overview.

Avidemux for windows is the right tool when the job is defined — cut, encode, filter, done. It does not try to be everything, and that focus is exactly what makes it reliable on Windows desktops and laptops without the overhead of a full NLE.
