%avidemux% --help
the above line fails - no command line help is showing up
%avidemux% --nogui --video-codec x264 --audio-codec MP3 --filters scale-down-to-480.avidemux-filters --output-format AVI --load "c:\some_name.mp4" --save test.avi
the above line should work nicely in theory - but in practice the parameters for audio codec and for the filters is non-functional, regardless of relative position to the load parameter.
you should use a tinypy script for your setup and use
avidemux_cli.exe --load foobar.avi --run foo.py --save bar.mkv
so you indirectly subscribe that the "--help" option and the other options are broken compared to the online docs.
by the way - there are no error messages sent to the console in case of bad parameters.
No, i'm saying that the best way to do it is to use the py script as it is used & tested much more
