Avidemux Forum

When saving anamorphic video to a MP4 container with Avidemux, you need to specify desired display aspect ratio in the configuation of the MP4 muxer.

Yes, in any future nightly build.

I would also usually recommend to prefer self-reliance over any dependency on official supply (independence requires just a Linux installation with quite a bit of memory and disk space), albeit I would need to verify that the old way to cross-compile Avidemux on Linux for Windows still works, or that the new one (requires DevPod, e.g. as AppImage, uses Docker) works sufficiently well.

I have converted a VOB file to MP4 using handbrake converter . This tool was the only video converter that was able to do the conversion Perfect without Narrowing the video to squashed !! I tried just about all other video editor/ convertors - Handbrake is the Only one that does it.
But Now when I use Avidemux to trim this video using "copy" vide Only mode , the same thing happens again & the video is squashed. What other Free Alternatives can I use to trim the mp4 video without Loosing the Header information that Handbrake had put in

Thanks!

Forgive me, will this appear in a nightly build?

Quote from: artifexor on June 26, 2026, 01:16:18 PMThe problem is the lrelease (qtchooser) executable which does not detect my QT6 installation even the right executable is here

Alternatively, does the solution path suggested in https://askubuntu.com/questions/1460242/ubuntu-22-04-with-qt6-qmake-could-not-find-a-qt-installation-of work?

This is the solution, successfully compiled with QT6, thank you very much.

qtchooser -install qt6 $(which qmake6)

Should be fixed by cubicLUT: interpret tab and space characters in cube files synonymously, thank you for reporting the bug and for the sample.

I tried 2.8.1 as well, that fails saying:

Load failed
Invalid file

The cube file I'm trying to use is direct from dji:

My apologies for the late reply. qtchooser doesn't support Qt6, can it be completely uninstalled? Alternatively, does the solution path suggested in https://askubuntu.com/questions/1460242/ubuntu-22-04-with-qt6-qmake-could-not-find-a-qt-installation-of work? Does exporting QTDIR set to /usr/lib/qt6 in the terminal used to run bootStrap.bash script help?

Is the failure to load the LUT file specific to this particular build?

In any case please provide the file for inspection and testing either as attachment to your reply or, when too large for that, by means of the link sharing feature of Google Drive, or via Dropbox, or Mega.

Attempting to load 3D LUT file:

DJI OSMO Action 5 Pro D-Log M to Rec.709 V1.cube

results in:

Load Failed
