# Change Log


Changes in Avidemux v2.7.6 – v2.7.8

New Features

Many new video filters added by courtesy of a href=""szlldm/a

A dedicated MOV muxer is now available, replacing silent fallback to

MOV muxing mode within the MP4 muxer.

A subset of color info relevant for HDR support is retained in copy

mode when both input and output video are stored in Matroska / WebM

containers. Settings to add or override color info have been added to

MKV and WebM muxers.

The indexer in the MPEG-TS demuxer now detects resolution changes in

MPEG-2 and H.264 streams which are entirely unsupported and suggests

aborting indexing. If the user chooses to continue, it records file

offsets of all resolution changes to the log. This allows advanced

users to split the file at these offsets using other tools like

head and tail into chunks which can be processed

with Avidemux.

YUV varieties of the lossless Ut Video codec are supported now for

decoding and encoding via bundled FFmpeg libraries.

Uncompressed 24-bit audio is now supported for a subset of file formats.

Limited support for 7.1 channel layout.

Decode and stream copy support for XLL substream in DTS audio tracks.

Audio properties are now updated on resuming playback. This allows to

start saving after an audio format change. When audio format changes

during playback, the FFmpeg-based audio decoder will output silence

and keep format rather than producing garbage.

An option to keep the identity of markers A and B instead of swapping

them automatically has been added to Preferences.

The keyboard shortcut for "Delete" action has been made customizable

with alternative keyboard shortcuts enabled.

Other Enhancements

Multi-threaded video decoding is now available for the bundled FFmpeg.

On powerful multi-core CPUs, this can drastically improve decoding

performance. A maximum of 8 threads can be created, but a conservative

custom upper limit of 4 is recommended. Values above 8 cause decoding

failures. Multi-threaded decoding and HW accelerated decoding are

mutually exclusive, changes require application restart to have


The maximum supported resolution has been increased to 8192x8192

The bundled FFmpeg has been updated to the 4.2.4 release.

Non-standard display aspect ratios can be configured in MP4 muxer by

specifying display width.

MP4 muxer accepts now MPEG-1 and MPEG-2.

The configuration dialog of the x265 video encoder plugin enjoyed

massive cleanup and refactoring by a href=""Trent Piepho /a, more Adaptive

Quatization Variance methods have been added.

Python interface has been substantially extended, includes now methods

to query segment properties, the number and filenames of loaded

videos, PTS of keyframes, methods to seek to time with preview

updated, to open file dialogs filtered by extension and a built-in

method to split filename extension from a given path.

Scripting shell now supports unicode characters.

On macOS, files can be loaded via Finder context menu or by dropping

them onto Avidemux icon in the dock.

On Linux, Jobs GUI and the CLI executable can be launched from

AppImage by creating a symlink with _jobs or _cli in filename

respectively and running the AppImage via this symlink.


Rate control was broken in some video encoders, especially in VP9 and

in NVENC-based encoders, fixed now.

Multiple issues in cut point checks for H.264 and HEVC streams in copy

mode, leading to incorrect check results, were identified and


The first two frames of external AC3 or EAC3 audio tracks are not

dropped anymore. This regression from enhanced protection against

false positives, added 3 years ago, has been finally identified and


Indexing of MPEG-TS files with HEVC video was broken when video stream

lacked access unit delimiters. The issue was identified and fixed

right after 2.7.7 had been tagged as released and is the reason why

version 2.7.7 was superseded by 2.7.8.

VU meter was grossly ahead of audio output on Windows, now it is just

a tiny little bit ahead.

Numerous other fixes and overall polish.


Avidemux is a free, open source cross-platform video editor for Microsoft® Windows®, Linux®, Mac OS X®, and BSD. It is written in C++, and you can use it for various tasks such as encoding (convert videos from one format to another), cutting (cut individual portions from a recording) or filtering (resize, deinterlacing, add subtitles, color correction, etc.)

. Avidemux offers built-in support for many popular codecs and files: AVI, MP4, ASF, DVD, MPEG, MKV. It is one of the best free video editors whenever you need to automate video processing or editing process. The software is released under the GNU GPL license and has been released (binaries) in both 32-bit and 64-bit versions.

Avidemux Review


- Avidemux works on all the primary operating systems. Linux users will appreciate having a native installation instead of having to use an emulator program like WINE.

- It has some standard video processing features and a few extra capabilities that help make editing a breeze. There's a 'calculator' option that quickly estimates the final file size based on your current settings. In most other programs, you have to work through several export menus to get to the file size information.

- There is some presets to quickly process videos for different types of DVDs and current mobile devices. There are also settings to improve the quality of playback if you're working with a low-quality file.

- Avidemux has been around for over a decade, but it still has a very active community. If you get stuck, post a question on the message board, and one of the members will help you.

- Have some videos to work on? This software can do group file editing.


- Avidemux has a somewhat dated interface; not the most professional looking freeware program out there. It has only a few icons and instead you have to rely heavily on the sometimes confusing menus.

- Some of the menu settings and names aren't intuitive for a raw beginner. Unless you're already familiar with terms like 'deblocking' and 'VBR time map,' expect to spend some time looking them up first.

- You may need to download extra codecs to work with uncommon video and audio file types.

Conclusion: Avidemux is a simple, relatively easy to use video editor that stands out from the crowd of other editing apps. Unlike the competing software out there, Avidemux supports most major file types including .avi, .mpeg, and .mp4. This program handles both simple processes like cutting and editing video files, and it also has a selection of filters.
