Validating a DCP

DCPs are in transition again. Without getting into the Whys and Wherefores, suffice to say that the end goal is a package that can automate more features more reliably for a broad range of users and machines. …even users who are just glad to have made it over the finishline, and who are making their first package with free software and who have only tested the DCP on …well, can’t test it until we gets us to the festival tomorrow morning….in a few hours.

There are hundreds of stories now of DCPs that get to a festival which will get QC’d on one set of equipment – Phew! Working – and then be found unable to play on another type of media player. Or, will not play on the same type of player because – it seems – it has different software/firmware. Or will play on the same type of player, even with a different software version, but on a projector with different firmware. Ah, the vagaries of digital. The potential variations are endless, even when there is a stable standard for equipment manufacturers to interpret and comply with. A professional DCP creation house will have several media servers and projectors to test a DCP on, but the less expensive solutions/situations are lucky if they have a friend who can play the DCP at the cinema two villages over.

Ongoing Sec – More Exploited Vulnerabilities Patched

Security Logo

12 November – Every freakin’ month (2nd Tuesday) there is a new set of Microsoft vulnerabilities, so much so that we have ignored reporting them.

But this month there is yet another set of Critical vulnerabilities that is being exploited in the field – read about it here at Krebs:

Zero-Days Rule November’s Patch Tuesday — Krebs on Security. This explains new Flash updates. [Your editor has eliminated Flash from his system…not worth the bother.]

But note: This does not cure the zero-day exploit that is capable of ruining your whole week~!~!~!


11 June – Another round for Adobe and Microsoft, explained by Krebs:

Adobe, Microsoft Patch Flash, Windows


14 May – Microsoft and Adobe today each released updates to fix critical security holes in their software. Microsoft’s patch batch tackles at least 33 vulnerabilities in Windows and other products, including a fix for a zero-day vulnerability in Internet Explorer 8 that attackers have been exploiting. Separately, Adobe pushed security updates for Flash Player, Adobe Reader, Acrobat and Adobe AIR.

So says Krebs On Security today. Get all the info: Microsoft, Adobe Push Critical Security Updates


6 May – Zero Day Exploit is not only in the open for IE8, but it is published for all hackers to study from.

 

If you must use a Windows computer, please change over to Firefox immediately (if you haven’t already.) Then read this:

Krebs On Security – Zero-Day Exploit Published for IE8


12 Feb – The normal tuesday repairs to the normallly insecure programs –

Fat Patch Tuesday — Krebs on Security


7 February – Critical Flash Player Update Fixes 2 Zero-Days — Krebs on Security |

These stories never end…not even interesting reading anymore. Just do the upgrades.

Updates are available for Windows, Mac, Linux and Android users. The latest Windows and Mac version is v. 11.5.502.149, and is available from this link. Those who prefer a direct link to the OS-specific downloads can grab them here. To find out if you have Flash installed and what version your browser may be running, check out this page.


16 Jan – Days after the critical Java fix, Kreb’s On Security announces that a new exploit not patch in the version 11 release is being sold on the black-hat black market. First, learn how-to and do turn-off Java until this is patch AND even then, only if you need it.
How to Unplug Java from the Browser — Krebs on Security

Second, read more about the sordid details here: New Java Exploit Fetches $5,000 Per Buyer — Krebs on Security

Security experts on Java: Fixing zero-day exploit could take ‘two years’ | ZDNet

Third: Point others to this site to learn “What Is Java” and how to use it if you absolutely must: What You Need to Know About the Java Exploit — Krebs on Security

 


 

 

13 Jan – Now it is Java wih the critical warnings…Read Kreb’s for the data, but one thing I noticed is that his link for the mac update was wrong and the auto-update that the Mac Java program points to gives an error. So here is the correct link for all OSs: Download Free Java Software, which should point to the right place. Here is where I got a successful Java for Mac download:
Oracle Ships Critical Security Update for Java — Krebs on Security Download Java for Mac OS X
Oracle Ships Critical Security Update for Java — Krebs on Security


 

8 January – Like the Australians needing new colors on their temperature maps as Ultra Hot turns to Double Extra Super Hot, Microsoft and Adobe are going to need new degrees above Critical and above Vulnerable. In this case, Microsoft should say, “Ultra Vulnerable Even After the Update”, As Krebs on Security explains: “… these vulnerabilities could be exploited to fully compromise vulnerable Windows systems without any help from users. …”

Read the entire piece since it has all the links for the Adobe Reader Flash Player plugin…and AIR and Acrobat…for both Windows and Mac OS.

Don’t delay…here is the link again: Adobe, Microsoft Ship Critical Security Updates — Krebs on Security

Black Screen Alert~! InterOp Losing Life Support

Remember “Paradigm Shift”? Of course not. Writers have been banned from using that overworked phrase for another 20 years. The same will soon happen with the misused terms “Perfect Storm” and “begs the question”. Notwithstanding, we need a way to describe the potential for Reality-laced Hyperbolic Activity that is coming to Digital Cinema screens everywhere.

Potential Points of Failure Quotient = 10.95. Hyperbole Quotient…OK, InterOp will be around a long time for legacy, but don’t expect it to continue for everything else.

Does that describe it? OK, let’s see how it can happen (and we’ll keep math and the SMPTE Police out of this.)

File Festival Deliverables

The days of delivering expensive film prints to film festivals is nearly over. While the percentage of digital projectors in the field is still less than 70%, it is possible the percentage is much higher at the leading exhibition facilities which are used for the festivals. And don’t forget that the number of skilled projectionists is going down, as well as the maintenance of that equipment.

The International File Festival in Melzo, Italy (just outside of Milan at the Arcadia Cinemas) is leading (as Arcadia always does) in this field. File Festival–Melzo, International

3Questions: OpenDCP – Now with GUI

3 Questions with OpenDCP creatorThe dream of creating DCPs for local commercials and film festivals by artists using simple yet affordable tools just took a monumental step forward with the latest advance of OpenDCP.

Created by a theater owner and long-time computer engineer, this tool uses a combination of Open Source tools to take a finished ‘movie’ and turn it into a package that can be played by a digital projection media player and projector. And, it is free.1

Ideas for mastering DCPs

Before sending a hard drive with a DCP at least check the DCP with the free or full version of Fraunhofer Easydcp Player. That way you will see if the DCP fails the basic tests done by easydcp player like “Check file hashes” and that the disk works and have the correct DCP on it. The doremi and Sony (with recent firmware) accepts NTFS disks, otherwise a ext2/ext3 linux disk could be used.

Open Source DCP Mastering

DCP Mastering is the technique of making a final product, such as a movie an ad or trailer, into the form that a digital cinema player and projector can handle. There are several products that do this from Dolby, Doremi and Qube, but they are not for the weak of pocketbook. 

Clyde de Souza just posted an article on RealVision.ae that explains the use of some open source software at:
Free Unencrypted 3D movie DCP mastering for Digital Cinema Servers.

There are several people who have tried different variations, and have lived to tell the tale:
