Audition audio export not loading #298

Open fredfred27 opened 7 years ago

fredfred27 commented 7 years ago

I am using Audition CC 2017 to export a 5.1 channel WAV file for use in OpenDCP. Upon trying to load it under the MXF tab, I get the error: "The selected wav file is not stereo, 5.1, or 7.1,"

Here are the selection I made under the MXF Tab. Type: WAV Label: Interop (or SMPTE) Frame Rate: 24 Multi-channel is selected

The file was exported from Audition CC 2017 as a 48kHz, 24-bit, 5.1 channel file. What seems to be the problem is the wrapper format. It is using the "RF64 Format" for files larger than 4GB. The file size after export is 4,895,328 KB. The playing length is correct at 1:36:41. It covers 139,224 frames. The other option for files larger than 4GB is to export in the "Multiple Data Chunks (Legacy Audition Format)". This exports a file that is 4,895,322 KB, but its playing length is incorrect at 1:22:49. I can create a 5.1 MXF in OpenDCP, but its frame total is only 119,276.

Any ideas?

Thanks, Maury

This is currently a limitation of an underlying library. You will need to split the 5.1 into 6 separate mono tracks.

Thank you for the reply. That is what I am now doing, and it works perfect that way.

Cheers, Maury
