Hi there,

I have a problem using the DCP tool with Davinci Resolve 11 (Full version).
Wenn starting to export all clips get a bizarre greenish unsaturated look.

Anyone else has this problem? Is there a simple solution to that? - maybe in preferences changing a colour space?

Or is the easy DCP in resolve not a fullfunctional tool which needs further software/hardware?

Thank you in advance!
Andreas

The EasyDCP included in Resolve is a trial - You need to pay for the plugin.
However, the DCPs are supposed to look like that because in creation the colourspace of your project is converted to XYZ which you can't view properly on a regular monitor

Resolve has an internal conversion xyz to rec709. Use that to play dcp on your rgb monitor. Settings/look up table/...
Be aware that the only way to accurately play a dcp and display an xyz color space is a cinema server or a xyz projector.

The easy dcp plugin, works even without licence but plays only for 5 or 10 seconds

thanks for your responses.
Did anyone try opendcp or dcp-o-matic with good results?

Problem is: I have to do it myself because creating a dcp by a company would cost 400€ or more.
There must be a cheaper way of doing this for no-budget-films right?

People online have had success with OpenDCP. I've tried it with the local cinema who has a Doremi Showvault system and it didn't like it. Incidentally, I tried to output a 2K SMPTE flat 25fps stereo package - not sure if the problem was something I could fix as I'm pretty new to this!
I've just downloaded DCP-o-matic and will give it a shot soon…hopefully…

Probably wanted an InterOp standard package. Maybe the disk OS... there are only a couple of hundred things that it could be.

Thanks JPo
I'll give interop a go.
I'm pretty sure the disk OS was okay. At the cinema they took the dcp folder and zipped it (on windows comp) before importing it into the server…and of course it didn't work.
Cheers!

DCP-o-matic works fine for me. And yeah, that greenish tint is normal, don't worry, in the cinema it will look good again

I had good luck with open DCP- well good luck also means I read everything very carefully talked to the tech about the system I was delivering to and used my previous knowledge and went in early in time for a check.

All looked and sounded as it should have.

I've also had good luck with DCP-o-Matic for quickly making DCPs from REC709 source files when there's no time/budget to get it made by the pros. With all these solutions, even the expensive licensed ones, you still need to get the DCP loaded onto the server feeding the projector which requires putting the DCP onto a properly formatted Linux drive with inode size of 128. The only way to do this is using Terminal commands on a Linux machine. Some newer DCP servers can accept drives of other formats but you can't count on that. And, of course, test, test, test...

I delivered several DCPs via USBStick (commercials/short film) or on a regular NTFS formated external drive.

No Problems so far.

But yeah, they like those Linux drives in this totally overpriced drawer better, because it copies faster, since that expensive cinema servers usually only have USB2.

As I said before, it's a joke - the whole digital cinema server landscape is totally outdated (like 10 years behind contemporary technology), and there is room for a ton of improvement, but there is also a monopoly going on.

This is not a problem. XYZ colour space looks like this on an RGB/Rec 709 monitor

Most of the new servers can accept NTFS formatted media. So that's not a problem with new servers.

Older servers can only read from Linux formatted HDDs (not all Linux formats -- only EXT2/3 with inode size128 ), on which the original delivery system of DCPs were based. Newer servers, while capable of reading NTFS format, will also read the original Linux format. So it's safe to deliver the DCPs in specific Linux formatted HDDs to be on the safe side and if you do not know on which server your DCP is playing.

It's not true that DCPs need to be delivered in CRU enclosures. They can be delivered in normal HDDs with USB3 interface. USB2 HDDs are okay, provided you give enough time to the servers (and they have the time) to ingest the DCPs.

For short DCPs (short films, trailers less than 4 GB) delivering in Pendrives formatted in FAT32 are perfectly fine. DCPs of short films and trailers can even be delivered in data DVDs also (readable in PC format) as all servers do have a DVD ROM (unless the drive has conked off).

For a summary of how you can deliver a DCP, this is a useful guide:

http://www.knuterikevensen.com/?p=437

This guide also explains how to properly format into NTFS using a Mac and also says how to format in EXT2/3 with 128 inode sizing.

Edit: By the way, it might look that the whole digital server system is outdated. So are DVDs. We can't do anything about the standards already laid out. As in DVDs, you can overcome the specified regions by writing region free DVDs, the standard way to have compliance of your DCP in all the servers is to go with specified Linux format.

Hope this helps.

Little known spec, the NTSC formatted disk is characterized by the phrase, 'Never Twice the Same Coding".

Probably an Apple product.

I am sorry, I actually meant NTFS. Corrected it in my post.

Of course - fixed it.
