Hi Carl, From what I gather (and I am just a beginner) - I may have created a DCP into a 1.78:1 when it should have been 2.39:1 . Would this cause a strange angular edge to the bottom right hand corner? If a film is shot in 1.178:1 - do you need to have that as the setting for ‘scale to:’? and should I ever adjust the container on DCPomatic?

I do have a question regarding the making of DCPs - we are struggling with creating them for a cinema. The bottom right hand side of the DCP when projected on to the screen curves up a little. Could this be to do with not converting the DCP into the correct ratio or the fact the cinema has a curved screen? For example a 1.78 ratio DCP has been made into 2.39 scope as I thought it selected them automatically. I hope you can help me understand.

Hi Carl, Yes the film files do have boxing - does this change things? Thanks, James Discover.film Somerset House, Strand London WC2R 1LA https://discover.film On 11 Apr 2018, at 16:07, Carl Hetherington <cth(a)carlh.net> wrote: There shouldn't really ever be any problems with edges, unless the projector itself is set up in some odd way. If a film is shot in 1.78:1 and you have a source file with no letterboxing or pillarboxing you would set the "scale to" to 1.78:1, the container to "flat (1.85:1)" and that's it.  The film should play back using the projector's DCI flat preset without any distortion. Can you send the full name of the DCP you made?  It has details of the aspect ratios in it.  You can send it to me privately if you'd rather.

I am guessing this is an optical issue by maybe projecting in a configuration the projector is not setup to do.

That way, DoM will scale the actual image rather than also scaling your boxing. So: crop to remove boxing, scale to 1.78:1, DCI flat container should do it.
