Hi Guys, I recorded some files with Sony PXW-Z190 camcorders in XAVC format with 4 channels of audio (2 external microphones on CH1 and Ch2 and internal microphone L-R on CH3 and Ch4). When I add the files as inputs in vMix only the first audio channel (Ch1) of the recording is associated on the audio side with the respective input; this channel is sent on both left and right channels of the respective input.

To be noted that I am using the latest version of vMix software.

And here is the media info of the file:

Format : MXF at 51.3 Mb/s
Length : 7.84 GiB for 21 min 54 s 520 ms

Video #0 : AVC at 46.6 Mb/s
Aspect : 1920 x 1080 (1.778) at 50.000 fps

Audio #0 : PCM at 1 152 kb/s
Infos : 1 channel, 48.0 kHz

Audio #1 : PCM at 1 152 kb/s
Infos : 1 channel, 48.0 kHz

Audio #2 : PCM at 1 152 kb/s
Infos : 1 channel, 48.0 kHz

Audio #3 : PCM at 1 152 kb/s
Infos : 1 channel, 48.0 kHz

Hi,
I made a small app that allows you to remap audio channels in an MXF into 2 and 4 channels.

The output files can be used in vMix with the correct channel separation

MXF 2 and 4 channel remapper
