Hi Carl Eugen,

Thanks for support.
Just to be clear, I inspect the MXF files (before/after audio replacement) in a dedicated MXF software as ffprobe/ffmpeg doesn't give any clue about these MXF header metadata in the console.

Here is my console out :

ffmpeg -i TEST_UHD_before.mxf -i TEST_UHD_audio.wav -map 0:v -map 1:a -map 1:a -map 1:a -map 1:a -codec copy TEST_UHD_after.mxf
