Export in MXF OP1A in square format\custom resolutions

Hi everyone,

I would like to export some videos for social platforms in MXF OP1A format, but in square or custom resolutions (either 1080x1080 or 1080x1920).

I can do this on any computer at work, with presets\settings created by the technicians of my company; but somehow I cannot do it on my laptop at home.

The only resolution that seems to be allowed in the export settings is 1920x1080 when I use the XDCAMHD 50 PAL 422 codec, the one I need to use as it is the only one my company's systems seem to digest.

And before you ask: I cannot go to work nor contact the technicians due to this coronavirus mess.

I have to try and fix this issue myself.

Any ideas about how to do this?

Thanks a lot in advance for your help,

Alex
