How to make a DCP

There are many people out there who work in cinemas or film making that would like to get there film or footage on the big screen, with cinemas going digital this has massively reduced the cost of this but the problem is the over complicated way of how the content is encoded.

You can get software to do this and a few do a direct output from Final Cut pro but you are looking at thousands of pounds for this, you can also send it to one of the many companies who do this but again this is going to cost you money.

There have been a few working on a open source version of this, up until very recently it was a very heavy code based way of getting it done but they have just released a GUI version and its now become much more easier to get your content to DCP and then on to a server.

You can read through the documentation on the web site but it took me a few goes to get it right, its written for someone who knew all the coding, i thought i would list what i did to get my footage on screen. The following was tested on a Doremi.

Making a DCP

Download openDCP from

Converting to the correct image.

It important to note your video clip needs to be 1920×1080 or 2048×1080, if it is not you will need to upscale the clip.

OpenDCP requires the inout image as Tiff, the quickest we to do this is Quicktime 7 Pro.

• Open the video in Quicktime 7, File -> Export.

• Select Movie to image sequence, in options select Tiff and 24fps

Export this to a folder “Image Tiff”

A still image could be used, I would have to be imported to a video editor and made as a longer clip and rendered back out in the correct resolution.

Sound to Wav.

As we have Quicktime 7 open we can now export the sound. The sound has to be exported to wav.
The parameters for the wav file are “Linear PCM, Rate 48.000 kHz, Sample size 24 bits”

OpenDCP will let you use a left&right or full 5.1.

To export sound you have to select the channel you want and export it as mono, open the clips preferences and you will see an audio tab.

From here you can select left as mono and right as unused, export this to “left.wav” then do the same for right. This can be done for full 5.1 mix.

OpenDCP.

JPEG2000

The Tiff images that we have exported need to be changed to Jpeg2000 XYZ, open openDCP and on JPEG2000 tab select the correct input directory (the folder with your Tiffs in) and a relevant output folder.
The options are very self explanatory, Frame rate needs to be at 24 to match the Tiff file export, Threads are the number of cores used on your computer and XYZ needs to be ticked for the correct colour spacing to be applied.

Once you have made the correct selections hot convert, this will not output a conversion from the Tiff images to JPEG2000 XYZ.

MXF Creator

The default settings are.

Select the input directory of the JPEG2000 XYZ files you have just exported. This is also where you select the sound you have exported.

Once you have made all the correct selections select an output folder for Image and Sound

DCP Package.

This section is very self explanatory, check over the relevant settings as it will have an impact on where and how the server sees the clip you are about to export.

I have not really messed around with the different setting as of yet, i just wanted to post about what i had done to get a DCP package out.
