Bizarre 5.1 audio issue
Posted: Thu Jun 01, 2023 2:52 am
Howdy folks!
We use DCP-o-matic on a near-daily basis for making trailer DCPs. However, this one totally threw us. We have a trailer ProRes file that is in a pretty standard audio configuration: 5.1 in L/R/C/LFE/Ls/Rs, plus stereo. However, when we do our usual channel configurations and output to DCP with DCP-o-matic, the resulting MXF has 16 CHANNELS! 10 of them are silent.
Here's where things get wacky. We've tried exporting the audio as a multichannel WAV, and then adding it as a separate element. We've tried encoding it to SMPTE MXF in another program and rewrapping with DCP-o-matic. We've tried re-encoding the ProRes file with ONLY the 5.1 audio. No matter what we do, DCP-o-matic spits out an audio MXF with 16 channels.
Any clue what might be going on here? We've tried this on multiple machines, both Win and Mac. I'm currently running v2.16.55.
Thank you!
