[XDCAM HD] How convert 2 mono tracks in MXF to 1 track stereo in MOV container

[pulkow...@gmail.com]

Hi,
I tried convert video file MXF (XDCAM HD 422) 2 mono tracks to MOV container with 1 stereo track.
Video is OK but audio is 1 track mono (mixdown?).
I use this command:

ffmbc -i "<SourceFileName.mxf>" -tff -ac 2 -target xdcamhd422 -vtag xd5c -y <OutputFileName>.mov

I know that I should use option "map_channel" but I totaly don't know how use it properly.
Can somebody help me what type in command line and why?
THX!

Please post the full output of  ffmbc -i "<SourceFileName.mxf>"  so I can understand the structure of your SourceFileName.mxf and I think I can help explain the use of map and why.

ffmbc -i inputfile.mxf -tff -ac 2 -target xdcamhd422 -vtag xd5c -y outputfile.mov

Syntax for audio mapping is

-map_audio_channel 0:1:0:0:1:0 -map_audio_channel 0:2:0:0:1:1

 

The numbering is InFile:InTrack:Inchannel:Outfile:Outtrack:OutChannel

Numbering starts at zero.

Thus, it says use first input file1, track 1 (first audio track), channel 1 (there is only one),

spit that out to the new file,  and do the same for the second mono track, but map that to the first audio track, next channel.

 

hth,
