Anyone else making homemade DCP's

We have been having some good luck making DCP's for Indy filmmakers or for pacakges of short films that we don't have on 35mm.

I use Adobe media encoder to generate a TIFF sequence from the video (FCP may work for this), then OpenDCP (free download - get the latest version 0.25) which has three steps 1. convert the TIFFs to JPEG2000s 2.package the sequence into an MXF file. 3. Create the final DCP folder.

One thing I have noticed is sometimes that black levels during fades to black between shorts does not fade fully before switching to the next short. Not sure if it has something to do with how the projector reads black or what. Must experiment more.

I wish there was an online tutorial that would break this kind of thing down to where the average person could figure it out. I would just like to make some custom "slides" in DCP format that I could stick into appropriate places..."Welcome to the Roxy" with a picture of the Roxy on it for five seconds or something like that.

Mike --

Send me a 1998x1080 (and/or 2048x858) image in some common image format and I'll make the DCP. If you just want a still image that fades in, stays on the screen for a few seconds, then fades out, and can have the logo itself already designed, it is trivial to make the DCP.

Mike,

If you have media already in HD and .mov then this program is better for you. Free DCP Builder, lets you take any existing hi-def .mov file and convert it to DCP

OpenDCP 0.25 can easily make a simple slide or slideshow. Essentially you use OpenDCP to create a JPEG2000 from a TIFF image. You then create an MXF slide of whatever duration. The final step is to create the DCP. Refer to the Wiki.

Nice feature! Is there any chance of getting the source code to the latest version? The latest that I have found is 0.19.

The pre-compiled binaries are available for OSX, Windows, and Linux. You can find the source code on GitHub, just search for OpenDCP.

I use openDCP myself.
Works pretty well. I forgo the GUI though.

Regarding the OP, what color space are you using and what is the projector?

Paul:

In the near future, my theater will be converting to digital and I'm curious about creating my own DCP's for showing slides and doing advertisement. My files are in a .Mov file format and you mentioned a program that you can use to convert from mov to DCP. Can you please share the name of that software with me.

Robert

Not sure of what Paul's using but ffmpeg is excellent for transcoding just about anything.

Robert,

A far better way IMO is to just take your source video stream and scale/crop/add-black-borders to make a DCI compliant image sequence that is DPX/TIFF 2048x858 or 1998x1080. Adobe Premiere works for this. Another (free) alternative that I exclusively use now is avisynth. It will read just about any video stream and write your TIFF's for you. If anyone is interested I can post details on how to get avisynth to work for this. I found it a bit tricky at first but it was well worth the effort.

Edit - Sorry, I missed the post about Free DCP builder, haven't tried it, but it defiantly isn't open source.

Regarding my fade to black problem.

I'm using a Christie Solaria 2220, with Doremi DCP 2K4

OpenDCP should give me the right colour space.

Paul,
Perhaps there's something in the newer version of openDCP but I always do the colorspace conversion and gama adjust with imagemagick via a shell script.
I was not aware openDCP did anything to colorspace actively.

Although, depending on what you're seeing. I can't say fo sure. It could just be how the server works.
I've noticed on our Sony's for example that a fade to/from black is still a shade of grey above blanking between content. Very noticeable in 2D.

OpenDCP performs an XYZ colorspace transform by default during the JPEG2000 conversion.
