Export multichannel audio, 15 channels or 7.1 Left Right?

[Gorki 360 cinematographer]

I´m working w a composer on a 360 video art piece. We want to screen it with live speakers, 15 of them. I need a 360 video that can contain 15 channels or 7.1? Any ideas if it is usable? I can´t export apple pro res since the 360 video player will not play it. It has to be h264 or h265 but then max ammount of channels seems to be 4 or 5.1 

Any help appriciated 🙂

Thx

I think you can export a 16ch MXF or MOV and convert to 16ch H264 or H265 with shutter encoder. 

Beware there's a minor bug in 16ch Adaptive tracks (you're only going to come across it if you want to do some muting in track mixer - A16 has to be muted for any other channel muting to work).

Thx @Trevor_Asq !  Where can I find out more? Do you remember the source?

use the h.264 or h.265 function and go to 'Audio settings' and set it to 'Multi' and assign the channels.

Looks like it might only go to 8 channels though - pretty sure that is a UI limitation. You should be able to get to 16channels with FFMPEG (which is what is underneath).

Otherwise Resolve will export a 24channel H264 or H265 MP4 (maybe more but their adaptive tracks stop at 24)
