Avidemux Free Download

Avidemux is a free, open source video editing tool available for Windows, macOS, and Linux — and the avidemux free download comes with no watermark, no subscription, and no adware.

It sits in the broader desktop video editing software category as a linear processor rather than a timeline-based NLE. That distinction is practical: load a source file, set your output codec and container, apply any filters, and export. No project files, no multicam, no color wheels. Trim, encode, filter — in that order.

What Avidemux Does Well

Cutting Without Re-encoding

The most useful operation in the editor is copy-mode trimming. Set the video output to Copy and the audio output to Copy, mark your in and out points with `[` and `]`, then export. The result is a trimmed MP4, AVI, or MKV with no quality loss and no re-encoding pass. Render time is effectively instantaneous because the tool is just remuxing packets.

This matters for archivists and anyone trimming dashcam footage, screen recordings, or raw H.264 clips from a DSLR.

Avidemux Video Encoding Options

Switch the video output to H.264 (x264) or H.265 (x265) and the encoder configuration panel opens directly. Set bitrate, CRF value, and profile from there. AAC or MP3 audio tracks are selectable independently. Output containers include MP4, MKV, AVI, and MOV.

The job queue (File → Job List) lets you stack multiple encode tasks and walk away. That is as close to batch processing as the tool gets — functional, not fancy.

Video Filtering Software Free of Charge

The Filters menu (Video → Filters) includes sharpening, deinterlacing, noise reduction, resizing, and subtitle burn-in. None of these require plugins or paid upgrades. Filters stack in order, and each has a preview window so the effect is visible before committing to an export.

Installing on Windows

System Requirements and Build Choice

The Windows installer is available at the official SourceForge page or the GitHub releases tab. Download only from those two sources — third-party repackaging of this GPLv2 licensed application has historically introduced bundled extras that the original does not contain.

The 64-bit build is correct for any Windows 10 or Windows 11 machine made in the last ten years. Minimum specs are modest: dual-core CPU, 512 MB RAM, Windows 7 or later. Realistically, any machine encoding H.264 at 1080p will want 2 GB RAM or more. No reboot required after install. The wizard is four clicks: accept the license, confirm directory, finish, launch.

Do not install the 32-bit and 64-bit builds simultaneously. File associations will conflict.

Safety Check

The GPLv2 license means the full source is auditable on GitHub. No tracker, no telemetry. VirusTotal scans of the official installer return clean results. Verify the SHA checksum posted alongside each release on GitHub before running the installer.

Format Support on Windows

Frame-by-frame navigation uses the left/right arrow keys. Scene detection is under Video → Scene Detection and outputs a keyframe list usable for cut planning.

For users who need the editor on other systems, the Avidemux build for macOS involves additional setup steps on Apple Silicon hardware.

The avidemux free download handles the majority of practical single-clip tasks — trim, encode, filter, export — without opening a heavier application like DaVinci Resolve or Adobe Premiere. For a dedicated Windows setup walkthrough, see the complete Windows installation and configuration guide.

If the workload stays within those boundaries, this open source video cutter earns its place on any Windows desktop. The avidemux free download is the correct starting point.
