the x264 profile command for this in ffmpeg is fairly straight forward to implement off of CLI – it is;
-profile:v high444
You will of course need to set your bit rates max/min and presets as desired but this profile setting will output a h.264 at 4:4:4.

Hi Peter,
MXF files are great because of the wealth of information that they can pack in to the metadata to describe the essence it carries however as a result there are a myriad of different ways of carrying audio in MXF files which will impact what is the appropriate mapping for you to output to extract the files you need.
I would recommend that you post the information you get from the source file by just running the -i command and pasting the results here for us to take a full look at.
The -map option is usually enough to allocate the mapping of your output into files, streams and channels (in that order).
e.g. 0:1:0:0:1:0
:::::tip – A regular gotcha for anybody dealing with numbers in this output is to remember that the first item whether it is a file, stream or channel will start from ‘0’
