Can I Put Multiple Films Into One DCP?

Yes — With Conditions

Combining multiple short films into one DCP is absolutely possible and often the most cost-effective approach for a short film programme. One DCP, one fee, one USB stick, one ingest at the cinema. But there are three things that need to line up first.

Frame Rate — Must Match

Every film in the programme needs to be at the same frame rate. A DCP runs at one frame rate throughout — the server does not switch gears mid-playback. If films were finished at different frame rates, they need to be conformed to a common rate before combining. This adds cost and potentially a subtle visual impact. If you are curating a programme and have any influence over how the films are finished, agreeing on a common frame rate before post production begins avoids this problem entirely.

Audio Levels — Should Be Matched

Five short films mixed by five different sound designers to five different loudness targets will produce an inconsistent experience in the cinema. One film will feel uncomfortable. The next will feel like someone turned the volume down. Reviewing and level-matching each film's audio before combination is worth budgeting for — often it is a matter of bringing certain films up or down by a few decibels rather than a full remix.

Aspect Ratio — Must Fit the Same Container

Every DCP uses one container: Flat or Scope. If your programme contains films at very different aspect ratios — a 1.33 film alongside a 2.39 Scope film — there is no clean answer. In a Flat container the Scope film will be heavily letterboxed. In a Scope container the square film will be heavily pillarboxed. The decision is which compromise is more acceptable, or whether separate DCPs are actually the right approach.

When Separate DCPs Make More Sense

Separate DCPs are better when: films are at significantly different frame rates; films have very different aspect ratios and the shared-container compromise is unacceptable; individual films also screen separately and need their own DCPs anyway; or the programme order changes between venues and programmers need flexibility. A combined DCP made from technically incompatible films will always look and sound like a compromise.
