FFMBC: Create Audio Streams on MXF file

[kennet...@gmail.com]

Hello.

I have and MXF XDCAM422 file with 8 audio tracks.

I'd like to make it a MXF XDCAM422 but with 16 audio tracks (video "untouched").

I'd like to replicate the original file audio tracks, for example: channel 1 in channel 9, channel 2 in channel 10, channel 3 in channel 11...

I tried something like:

ffmbc -i "C:\ffmbc\IN2.mxf" -vcodec copy -timecode 00:00:00;00 -an "C:\ffmbc\OUT2.mxf" -target xdcamhd422  -acodec copy -newaudio -acodec copy -newaudio -acodec copy -newaudio -acodec copy -newaudio -acodec copy -newaudio -acodec copy -newaudio -acodec copy -newaudio -acodec copy -newaudio -map_audio_channel 0:1:0:0:1:0 -map_audio_channel 0:2:0:0:2:0 -map_audio_channel 0:3:0:0:3:0 -map_audio_channel 0:4:0:0:4:0 -map_audio_channel 0:3:0:0:5:0 -map_audio_channel 0:4:0:0:6:0 -map_audio_channel 0:7:0:0:7:0 -map_audio_channel 0:8:0:0:8:0 -map_audio_channel 0:1:0:0:9:0 -map_audio_channel 0:2:0:0:10:0 -map_audio_channel 0:3:0:0:11:0 -map_audio_channel 0:4:0:0:12:0 -map_audio_channel 0:5:0:0:13:0 -map_audio_channel 0:6:0:0:14:0 -map_audio_channel 0:7:0:0:15:0 -map_audio_channel 0:8:0:0:16:0

but it did not work, I think it is because the streams 9 to 16 do not exist yet.

Any help will be appreciated.

Thank you!

I recall doing this to go from 2 to 8 tracks but it has been some time.  Can you add 8x more "newaudio" sections?

Thank you so much, Eric!

It works!

It may seem obvious, but I was really not realizing I needed new audio for those channels.

ffmbc -i "C:\ffmbc\IN2.mxf" -vcodec copy -timecode 00:00:00;00 -an "C:\ffmbc\OUT2.mxf" -target xdcamhd422  -acodec copy -newaudio -acodec copy -newaudio -acodec copy -newaudio -acodec copy -newaudio -acodec copy -newaudio -acodec copy -newaudio -acodec copy -newaudio -acodec copy -newaudio -map_audio_channel 0:1:0:0:1:0 -map_audio_channel 0:2:0:0:2:0 -map_audio_channel 0:3:0:0:3:0 -map_audio_channel 0:4:0:0:4:0 -map_audio_channel 0:3:0:0:5:0 -map_audio_channel 0:4:0:0:6:0 -map_audio_channel 0:1:0:0:7:0 -map_audio_channel 0:2:0:0:8:0 -newaudio -map_audio_channel 0:1:0:0:9:0 -newaudio -map_audio_channel 0:2:0:0:10:0 -newaudio -map_audio_channel 0:3:0:0:11:0 -newaudio -map_audio_channel 0:4:0:0:12:0 -newaudio -map_audio_channel 0:5:0:0:13:0 -newaudio -map_audio_channel 0:6:0:0:14:0 -newaudio -map_audio_channel 0:7:0:0:15:0 -newaudio -map_audio_channel 0:8:0:0:16:0

Again: Thank you, Eric!
