Number of channels defined in MOV audio (8) does not match Asset channel mapping count (2).
The MOV channel count attribute does not match the audio channel mapping specified in the metadata during upload to the Backlot Delivery UI. This error code is returned when the affected source is a MOV file.
If the MOV file has the correct number of channels then you will need to update your channel mapping tag by performing a metadata only redelivery through the Backlot Delivery UI. Please contact your Netflix representative and ask them to adjust the Source Request to "New metadata only".
If the MOV file has the incorrect number of channels then you will need to perform a regular "New source and metadata" redelivery.
