Digital cinema, democratized.

DCP-o-matic is a free, open-source program to create Digital Cinema Packages (DCPs) from videos, images, sound and subtitle files. You can use it to make content for playback on DCI-compliant cinema projectors.

It can take files in many different formats, including MP4, Apple ProRes, MOV, AVI, M2TS (from Blu-Ray), VOB (from DVD), WMV, MKV, JPEG, PNG, TIFF and lots of others.

It will run on Windows, Mac OS X and Linux      and is in use in 59 countries around the world for creation of snipes and adverts in cinemas, education, film festivals and much more.

I hope everybody is keeping as well as can be expected in these troubling times. I am lucky in that I don't depend on the DCP-o-matic project for my main income, and my day job is (currently) continuing normally on a work-from-home basis. If your one-off donations or regular subscriptions to DCP-o-matic are causing you any financial difficulty please do not hesitate to cancel or postpone them.
