DKDM query again

Post by filmwallah »

Hi,

I have been asked by a distribution house to provide DKDM for a DCP which I would be encrypting using DCP-o-matic.

He has given me three certificates which looks like this: SCRABBLE-MASTER1.sha256.chain.pem

What is the correct procedure to go about it?

Roughly speaking:
  • Extract the last (leaf) certificate from the chain you have been given.
  • Open your DCP-o-matic project and choose "Make KDMs..."
  • Add a cinema, calling it whatever you like.
  • Add a screen to this cinema and load its certificate from the leaf certificate from your chain.
  • Make a KDM for that screen: that is your DKDM.
Let us know if you have trouble.

While I go for encryption of an existing unencrypted DCP, using folder option it creates several files. It's creating a folder with DCP name having all the DCP files (assetmap, video, audio, cpl, pkl and volindex), which is normal. I can also see an info folder, a metadata xml and a video folder outside the DCP folder.

What are they? Is this normal for an encrypted DCP? Do I need to send these files too as part of the encrypted DCP?

Looks like DKDMs are getting generated with the cert leaf, which are kdm.xml.

Those files are explained here. info / metadata / video are not part of the DCP.
