Avidemux Forum

I appreciate Avidemux.
However it lacks an important feature:

Avidemux does NOT keep all the EXIF header data fields when I re-encode an existing *.mp4 video into another *.mp4 video.
At least it does not copy the GPScoordinates from old to new video.

And the internal (!) Creation and LastModified Date

Why can't this super simple "keep EXIT" feature be implemented?

At least as user option for .mp4.

I guess 97% of all video conversions are from .mp4 to .mp4.
So a lot of users would profit from this function

Adding a feature to this program that while removing sequences the program knows where each subtitle timestamp is moved after edit without having to go into a srt text editor and changing all the timestamps based on when they're suppose to appear manually.   

In-tree build in a RAM disk using the script by Moshe Gottlieb (with build dependencies already installed and thus commented out in the script) works for me on my Mac mini M1, macOS 26.5.

pkgutil --pkg-info=com.apple.pkg.CLTools_Executables
package-id: com.apple.pkg.CLTools_Executables
version: 26.5.0.0.1777544298

Just to use clear terminology: this is not about appending audio, which is impossible with Avidemux. This is about adding an external audio track. You would need to either copy the audio file to a different path or duplicate it (on *nix OSes: create a link to the original file under a different name) to be able to re-use it as another external audio track in Avidemux.

I just tried to ADD ((APPEND audio 2ND TIME) audio BUT avidemux COME UP "ERROR" -some tracks are used multiple times - ANY WAY AROUND THIS ?

Two things of note: Avidemux (avidemux_mingw64_20260516.exe) creates a folder named "x264" on C: for me if x264 is configured.
And I couldn't login to the forum via login-button. I had to click register and then I was able to click the login-button.
Keep up the good work, eumagga0x2a.

Since upgrading to Ubuntu 26.04 I can no longer build avidemux from git. This is because cmake fails to generate the QT6 part with the following error:

  Imported target "Qt6::GuiPrivate" includes non-existent path

    "/usr/include/x86_64-linux-gnu/qt6/QtGui/6.10.2"

In advance: I don't know if this feature already exists in newer versions. I'm still using Avidemux 2.8.2 241214 build - the last that works Windows 7 ( ) but if I ever change my system this feature would be veeeery handy: when you select part of video (with start and stop markers) it would be nice if the playback would stop at the end marker. It could be an additional option in settings.

When I run job control the first job always fails? Why is this?

This stopped working sometime in the last few months. I don't remember if it broke with Tahoe 26.3 or 26.4 (my last successful build was in mid-February) but it's still broken with 26.5:
