extract/rip DCP to movie file

[Eric Sebalsky]

just wanted to let you guys know that it is finally possible to do this in a very easy and HQ way! the latest free version of davinci resolve (lite 11.1) is able to read a DCP.

just navigate the library to the location of the DCP and a movie clip (with 5.1 sound) will show up. you can then add it to your mediathek and create a new timeline. check the following first:

• set the project settings accordingly (for example there is a "DCI scope" resolution preset)
• go to the "edit" tab and open up the audio mixer and set it to 5.1 to see/hear all of the channels playing
• you can reedit the DCP here or apply filters/grading/scaling/framerate conversion
• go to "delivery" to export it to e.g. ProRes with 6 channel audio

note: the free lite version does not support DCP export, it can export jp2000 but not in the XYZ color space. also you'd need "easyDCP creator" to create a DCP within davinci resolve.

Just tried and after a few seconds the image goes low quality wit a
watermark "EasyDCP demo" just like in the preview.

But for those with an EasyDCP license is certainly good news.

so what other freeware ways on mac are there?
ffmpeg? of course for unencrypted DCPs only.

Never managed to make ffmpeg work in a Mac, go with Virtualbox and Linux.
Tried once and colors didn't convert from XYZ. It's a very slow conversion.

This is my collection of notes about it. Have fun.

Try Homebrew if you want linux type applications or libraries on OSX.
It's quite nice.

Once homebrew is installed, then install ffmpeg with 'brew install ffmpeg'
