There is no clean way to convert 30fps to 24fps. As such, you will probably need to stay
with 30fps, and create a SMPTE DCP. I guess you are pretty safe with a 30fps DCP, most
systems should be able to play it.
I guess your footage is in 1920/1080 without any inherent letterboxing, that is, 16:9 full
frame?
I would suggest you scale to 16:9/1.78, and choose a flat container. You will have some
black bars left and right that way, but you will have them in anyway in typical cinemas
since, even when you play a 16:9 container, the black bars will be there. No big deal. You
could do a full frame scale to flat, but that will crop away some image from top and
bottom.
Cinema presentation is special. Depending on the specifics of the venue your film is
presented at, you will either see these issues, or not. Depends on projector type,
masking, etc.

Hi Carl,
I am using the DCP-omatic to convert my film for a festival. I'm having a bit of
trouble and hope you can help me.
It was shot in 30fps, but the programs says that is an unusual frame rate. Should I
change it to 24, and if so, do I just change it under the DCP tab? I want to make sure the
video quality won't be compromised. But it sounds like it's okay to leave it at
30, from what I've heard.
The program is also advising that I create an SMPTE DCP instead of an interop, because of
the frame-rate. What is the difference? Should I do that?
Also, under the DCP tab, I set the container to 16:9, but the program is saying if
possible to put it in scope or flat, but those aren't the right size of my film, and
leave those black edges on the sides of the picture.
Please help me if you could. I've been working on this for a few days, and have to
complete it soon for it to show in the festival.
Thank you!
Josh
