For broadcast, we always need a workable multichannel project solution to export MXF files to multiple audio tracks when transcoding MXF to ProRes 422 MOV, ProRes 422 HQ MOV, ProRes 4444 MOV, etc for post production in FCP.

"Recently I have a multi camera project and everything works perfect but when I export to an MXF file the sound as a "blank frame" in sound. I tried various ways to export and every time I got this frame in the same place. Tried to export with 2 channels, 8 channels, stereo timeline, multichannel timeline and everything result in a MXF in this audio issue."

At present, there are no MXF encoders can directly export multiple tracks as individual channels in a MXF file. Premiere always mixes down all audio channels to the channels 1 & 2, which means that only channels 1 & 2 have audio, the other are blank.
