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. Here is a workable solution to the multiple audio tracks exporting under the situation that you edit multi-stream MXF file in FCP. Aunsoft TransMXF Pro for Mac, is the only completely multichannel project solution to preserve, separate, and export multiple audio streams from original MXF. No matter MXF footages from Panasonic P2, Canon or Sony camcorders are recorded with 2, 4, 8 or more audio tracks, you can easily preserve all tracks or get separate channels of audio in MXF for FCP 6/7/X editing.
Below is a simple tutorial to convert MXF to FCP X with exporting 8 audio channels in MXF with stereo timeline. Due to the advanced audio and video synchronization technology, the output file will with video and audio in perfect sync. Apart from multi-track MOV, you can also convert MXF to MKV and MP4 with 2 channels, 4channels, 8 channels or all audio tracks from source MXF.

Click "add video" or "add folder" to load multiple audio channels. You can also directly drag files to the program. The program supports batch conversion and allows you capture images.
Step2: choose the output format
Click the "format" and choose the "Multi-track Video -> Multi-track Apple ProPres 422(*.mov)" files as the output format.
Step3: Set multi-task settings
Click "settings" to convert multiple audio tracks MXF file to FCP X. The screenshot shows 4 tracks of audio, if your source MXF with 8 tracks, you will get 8 channels here. You have more choices, if you don’t want to keep all audio tracks, you can uncheck undesired ones. And you also can mix multi-audio tracks into individual track.
Step4: Convert MXF files into multiple track MOV
Click "Start Conversion" icon, TransMXF Pro for Mac will convert MXF to multiple tracks MOV with high quality. You can preview output file when conversion completed.
