2.0 Channel DCPs

Post by rl1983 »

Hello,

We've been making trailer DCPs, and I've noticed that some of the 2.0 content seems to play out of Center and Subwoofer tracks only when decoded with Pro-Logic? Any insight into this? Not all the 2.0 files do this, just some.

Hmm, why should anything stereo play out the center without Dolby Prologic applied? That is just normal. Most cinemas use a 1:1 channel routing, so Stereo audio simply plays out L and R.

If you only get Stereo source footage, then use DCP-o-matics Mid/Side Decoder.

Since you are using a Pro-Logic decoder, it is doing its job. If the audio on the Left/Right are substantially the same, the PL decoder will, correctly, decode that to mono and play out of center.

Thanks, that does make sense. I will try the mid-side decoder and see how that works.

Thanks!
