DCI projection standard (4K, 2K) for digital cinema auditoriums — not streaming. Delivers robust image fidelity with encryption for theatrical distribution.
D-Cinema—this is the digital cinema standard we have been working with since the mid-2000s. It does not refer to any streaming resolution, but rather a specialized projection format for cinema auditoriums that adheres to the DCI Specification (Digital Cinema Initiatives). At its core, it's about lossless, high-resolution image reproduction with strict technical specifications—4K (4096 × 2160) or 2K (2048 × 1080)—without compression in the classic sense.
On the camera side, this means we shoot in formats like ARRIRAW, DCI ProRes, or other high-quality intermediate codecs that are later prepared for D-Cinema output. The workflow fundamentally differs from what goes to the internet or streaming platforms. The file sizes are substantial—a 90-minute film in D-Cinema quality heavily taxes storage and bandwidth. Therefore, in editing, we often work with proxy files and only convert to the final DCI package at the very end. This is not a simple rendering process like with other formats; here, there are strict color science, gamma curves, and metadata requirements that must be met.
The practical advantage: D-Cinema projectors are specialized. They project light in a directed and focused manner without the stray light issues of standard projectors. This results in sharper, higher-contrast, more precise image reproduction—especially in dark scenes and fine details, the difference is immediately apparent. Many cinemas that have genuine D-Cinema certification are better equipped than those that only operate HD projectors with DCI adapters.
On set, this concretely means we calculate with this target output during color grading. The color gradations, the sharpness, the black levels—everything must work for D-Cinema projection, not for 8-bit web compression. That's why we often work on the grading monitor with a calibrated DCI mode to see how the footage will appear in the auditorium later. It's a different look than what appears on Netflix.
