Hello all,
I recently used DCP-0-matic to modify an existing DCP to update captions. I created (and tested) new OV and VF files. I zipped both files individually and place them on my Frame IO account.
A user downloaded and unzipped the OV file and attempted to load to a older Doremi server. They told me that the server did not even see the DCP folder on the drive.
Due to critical time issues, I then posted the original DCP (prior to my work in DCP-o-matic) on my Frame IO account without zipping it. This file was downloaded and used with no issues on the same system.
As a test, I downloaded the problematic zipped DCP, unzipped it and it plays without issues using DCP-o-matic Player.
Does anyone have any ideas as to what might have happened and what steps I might take to eliminate the problem?
Thank you,
Jef

Re: Possible DCP delivery issue
Hi,
Was the user who tried to load the DCP onto the server experienced with DCPs? If not, there a quite a few things that can go wrong.
Otherwise, the first thing to check is that you only zipped the _OV folder (containing ASSETMAP.xml, VOLINDEX, and some MXF files) NOT the one containing metadata.xml, video, log etc. Unfortunately there have been a couple of places recently suggesting that you should provide the complete DCP-o-matic project folder to cinemas, which is 100% wrong.

Re: Possible DCP delivery issue
Maybe they used a 'bad' unzip software. Do you use a Mac to create the ZIP? Is this OV/DCP larger than 4GB?
Then, they need to use a Mac to unzip the ZIP, or, in windows, a moderately recent version of 7-ZIP (from v17.01 up). Note this is not about 7-ZIPs own 7z Format, it's just it's ability to uncompress ZIP files larger than 4GB that have been created on a Mac using the Finder's internal 'archive' function.
Of course, other reasons are possible as well, as they may arise when unzipping very large ZIP files - running into temporary storage limitations, or unzipping on unreliable USB memory sticks, etc.
