The movie is natively stereo. The DCP-o-matic website suggested for stereo to click the Mid and Side (M/S) processor to create a centre channel, which is what I did here. This is my first time making a DCP and want to make sure I'm generally on the right track here?
In general, this looks okay - I am looking at the RMS for Center and L/R. Depending on the intent, overall level might be a bit too low (-24 LUFS is a bit soft). For a first blind test, I would probably raise gain by 3dB. But again, it depends a bit on the intent. Some stuff wants to be soft.
