DCP in 2048x1080

PostWed Dec 06, 2023 1:49 pm

Hi,

I usually deliver DCps in Flat and Scope and now i got an inquiry, where the footage is shot in 2048x1080.

From what i read it should be part of the SMPTE DCP Specification:
Does anybody have experience with a DCI DCP, i´m a bit hesitant, that i would play nicely on almost all DCP Servers, but in theory it should run smoothly....

Thank you...

It's technically part of the DCI spec, but 2048x1080 is not widely accepted at "regular" movie theaters and festivals. Here are the theatrical DCP formats they expect:

1.85, 2.39, and (sometimes) 1.78 are the main theatrical release formats. I can remember a case where a "full container" 2048x1080 file resulted in a server crash. I think it's important for filmmakers to actually shoot in formats that can legitimately be shown in theaters.

Of course, there are optional formats like 2.00 and 2.66 that can be shown within a 2.39 container -- basically, scope with letterbox top and bottom.

You can crop 2048x1980 to 1920x1080 and just lose a little bit top and bottom (about 64 lines top and bottom), and that will work.

Thank you for your answers.
Yeah, that´s the dilemma, it should be part of the Specification and should work, but practically i read about servers crashing, festivals not accepting it, etc.

I guess i will call some projectionists and see, what they have experienced.
Worst case i will recommend cropping to the standard resolution, just to play it save.
