MXF Multichannel mono export broken in latest Premiere version

Hi @digitlman - I'm glad that you are able to workaround it for now.  I'm sorry this is an issue.  I will let you know when I hear something from the team.  Thank you for your help and patience.

It certainly has something to do with the current presets both custom and adobe generated. I was able to take my old preset and change the video codec to 35 and then back to 50 and the checkbox autofilled with the check. I then saved it as a new preset and was able to choose it again on another sequence and it seemed to work.

HI @digitlman -  Let me know if you are able to workaround or need additional help.

Again,  sorry about this.  I will check with the developers and see if there is a quick fix.

Thanks, I concur that it seems to be a quirk with the presets. If i change out the codec to something else and then swap it back then it has the box already checked. This will be a little tough as we process tons of files but we will work with this until there is a fix. I will try making a new preset and see if that does anything.

HI @digitlman - I can repro this bug,  This is just bad and sorry for the frustration.  I have been trying to find you a workaround.  The issue seems to be everytime you select a custom preset the Separate Mono Tracks checkbox gets bonked.  

To get out of this loop can you try and choose a different export in the presets like h264 (it doesn't matter) and then manually change the format to MXF OP1a and manually set your video settings.  Let me know if that helps.  I'm currently looking to see where we store the export presets and if this doesn't work hopefully you can just delete a file and have it rebuild.

I also just tried the beta version.

launched it, created new project, new sequence, chose your broadcast 1080i 8 discrete mono track preset.

imported a mono wav file. dropped it onto 3 different tracks, clicked export

clicked more presets, chose the xdcam50 ntsc 60i preset

twirled down the audio options and cant click the mono tracks box.

 I tried picking that basic default one and it does not work for me.

Hi @digitlman - I do not see a codec labeled "XDCAM 50 60i" within Premiere Pro.  The closest I have found is XDCAMHD 50 NTSC (4:2:2) and when I export with the separate mono tracks it does embed discrete tracks.  

Can you share a screenshot of your video codec settings?

latest premiere, about says 25.0.0 build 61

export is standard XDCAM 50 60i we are sending to Evertz broadcast playout servers.

Audio is expected as such:

nothing has changed on our end, we are using the same sequence and export presets as before.

I tried from scratch also and nothing works. tried on other machines, made project from scratch and unable to check the box on the export.
