Using the Linux CMD Line with the following;
avidemux3_cli --load input_1.mp4 --output-format mp4 --save ./output.mp4
We see output but the source PAR=64:45 is changed to PAR=1:1 on the output MP4.
Is it possible to preserve the PAR value using the cmd line?
Doesn't appear to be covered in here; https://www.avidemux.org/admWiki/doku.php?id=using:command_line_usage (https://www.avidemux.org/admWiki/doku.php?id=using:command_line_usage)
I guess you would have to use a project script to pass necessary config to the mp4 muxer. The CLI documentation is utterly outdated.
Are these issues related?

Both topics are related featurewise (PAR of output = PAR of input), but this one is focused on the inability to pass PAR to muxers on command line. Current internal interfaces used by Avidemux IMVHO don't allow the former and probably also not the latter.
