MXF : 4 x Mono Audio Support is missing?

Great to see that MXF AVC 4:2:0 is now supported (as this is the default format for my XF400). There is no issues in now importing the MKF clips into PD and the info correctly shows that it contains 4 x Mono Audio Tracks. 2 from the Scratch Audio Mics and 2 x XLR Inputs.

The issue is there appears to be no way to display, edit, or mix each of these tracks individually. Even if I split the Audio off in the timeline, and then paste to individual audio timelines, there is no way I can see to pick Ch1, Ch2, Ch3, or Ch4. The MKV workaround of using "Languages" does not appear.

I'm hoping I'm blind and just missed the option on how to expose each of the tracks, otherwise I'd say the the new "MXF Support" is not fully true. PD 64 Bit-Win10 64 Bit-32GB RAM-80TB HDD

jmone, I don't see that you are missing anything, appears to be another support oversight with the audio. Similar discussion here: https://forum.cyberlink.com/forum/posts/list/83388.page#post_box_345349 but there user was starting with the unsupported 4:2:2 format but similar audio issue.

I also think if you try to extract audio from the media room for your file you will just get garbage too.

Thanks, that is what I thought so I've updated one of my PD Fix Utilities (based on ffmpeg) that will mux the MXF (or MP4) files with Multiple Mono Audio Tracks to MKV (lossless). You can then import these new MKV into PD19 and use the Languges option to expose the different Audio Tracks in the Timeline. There are two versions:

MXF (or MP4) to 4 Mono: This will put all 4 Mono Tracks and the Video into an MKV Container that PD 19 will like.
MXF (or MP4) to Stereo & 2 Mono: This will mix the 2 Mono Tracks from the Internal Stereo Mic to a single Stereo Track and keep the 2 x Mono XLR Tracks and Video as well. This is probably the best option, as you now get good stereo from the On Body Mic and with the seperate Mono tracks (eg from a Shotgun and/or body Mic) you can now individualy adjsut the audio.

To use, just unzip to a folder, place your MXF or MP4 files (can be in sub folders) in that folder and run the BAT File. It will create a MKV version for each MXF or MP4 Files (including files in Sub Folders).

It is pretty easy to edit the Batch Files for different combinations or number of Audio Tracks (eg A0, A1, A2, A3 etc) if needed.

Thanks
Nathan

Note: This will not help with 10-Bit 4:2:2 HEVC compatibility with PD19

...And here is what a MXF to Stereo & 2 Mono MKV file looks like in PD19.
