Re: Mid-side decoder removes stereo separation?

I had the idea to try this and fix the created Mid/Side MXF by simply loading it into Audacity, 're-invert' one channel, save, and create a new DCP with the fixed audio, then compare both. It's not overly complicated. A comparison in our cinema should be promising. The way it is now, L/R will suffer...

Re: Pillar Boxing in 16:9 Ratio

Cropping or pillarboxing are your only options for 16:9. Choose a 2k or 4k flat container.

Re: Mid-side decoder removes stereo separation?

It will work better in the cinema, but there is a current flaw in DCP-o-matic that inverts Left vs. Right during the Mid/Side Process. This will give a very thin sound when played about close stereo monitor systems, and especially when you mute the center speaker. I reported this to Carl, don't know...

Re: How to create DPX format?

Why would you want to create DPX with DCP-o-matic ? DCP-o-matic is the endpoint for cinematic distribution, not an intermediate one.

Most video editing/grading applications allow to create DPX files.

Re: Sharpen effect

The filter may have a rather unintuitive name, but - right-click on the content, choose 'Advanced Settings' -> 'Video filters' -> Edit, and use the unsharp mask/gaussian blur filter.

Re: Forensic Marking - KDM

That's a bit of a secret. The watermarks are repeated all over the run length of the DCP. As far as I know, these methods have been licensed from some companies like Thomson or Philips. These companies supply tools that can be used to analyse a video recording of the content. Usually these tools are...

Re: Encoding server using too many threads

Do you have only the encoding server installed in this old Mac Pro (as all modules are separate installs on the Mac)? If so, install DCP-o-matic main, and then start it up and go to preferences. You can set the amount of threads to use there. Maybe you had it set it there once and forgot about it. A...

Re: Forensic Marking - KDM

When forensic marking is active - and it is the norm for encrypted content - then the DCI playout server adds invisible and inaudible watermarks to the content while it is being played out in the cinema. These watermarks contain the serial number of the server used for the playout, as well as date a...

Re: Is the mid-side decoder feature in DoM a unique function?

I think it's working nice enough in it's current version, but guess it needs a tweak. I can't remember wether I filed a bug on Mantis. I think Mid-Side decoders use a very basic processing that works for most typical material - they are intended to direkt voice/dialog to the center speaker, and in t...

Re: DCP Job Fails Without Error Message

Never use special chars in DCP titles and transport folders/media path names. DCP-o-matic should catch it normally, but still, don't push it.
