If your film needs a Digital Cinema Package for theatrical distribution or festival screenings, Korean facilities offer DCI-compliant mastering with fast turnarounds and competitive economics. Here's what the process looks like and what to expect.
What Is a DCP and Why Does It Matter?
A DCP is the standard format for projecting content in movie theaters worldwide. It's not a simple file conversion — it's a specific encoding process that packages your film's video (compressed as JPEG 2000), audio (uncompressed PCM), and subtitle data into a format that cinema servers can ingest and play back. Getting it wrong means your film doesn't play, or worse, it plays with artifacts, sync issues, or incorrect color.
DCPs come in two varieties: encrypted (requiring a KDM — Key Delivery Message — unique to each projector for each screening window) and unencrypted (open, typically used for festival screenings and review copies). Most theatrical distribution requires encrypted DCPs; most festival submissions accept unencrypted.
The Mastering Process
Step 1: Source Material Preparation
You provide the mastering facility with your finished, color-graded master — typically a TIFF or DPX image sequence with separate audio stems (dialogue, music, effects). The color space should be DCI-P3 at the appropriate resolution (2K: 2048×1080 or 4K: 4096×2160). If your grade was done in a different color space (Rec.709, ACES), the facility will handle the conversion, but it's always better to provide source material in the target color space.
Step 2: JPEG 2000 Encoding
The image sequence is encoded to JPEG 2000 at the target bitrate. For theatrical features, the typical target is 250 Mbps maximum, with most facilities encoding at a variable bitrate that averages 150–200 Mbps. This encoding process is computationally intensive — a 4K feature can take 8–12 hours to encode, depending on the facility's hardware.
Step 3: Audio Packaging
Audio is packaged as uncompressed PCM at 24-bit/48kHz. The DCP supports multiple audio configurations — stereo, 5.1, 7.1, and Dolby Atmos (as a separate Atmos supplemental package). Most theatrical DCPs include at least a 5.1 mix; Atmos is increasingly expected for premium theatrical releases.
Step 4: Subtitle Integration
If your DCP requires subtitles (for international screenings or accessibility), these are integrated as XML-based subtitle tracks within the DCP structure. Korean facilities are experienced with multi-language subtitle integration, which is useful if you need Korean, English, and other language subtitle tracks in a single package.
Step 5: QC and Verification
The completed DCP is verified by playing it back on a DCI-compliant server (typically a Dolby, Barco, or GDC cinema server) to confirm correct playback, audio sync, subtitle timing, and encryption functionality. This QC step is essential — a DCP that encodes correctly but fails on a specific server configuration will cause problems at the theater.
Encrypted vs. Unencrypted
Unencrypted DCPs are simpler and faster to produce. They play on any DCI-compliant projector without additional authorization. Use these for festival submissions, press screenings, and review copies. Turnaround: typically 2–3 business days.
Encrypted DCPs require a KDM for each projector at each venue for a specific screening window. This adds a layer of security management — you'll need the cinema's server certificate to generate each KDM, and the facility must manage the KDM distribution process. Turnaround: typically 3–5 business days for the initial DCP, plus ongoing KDM management for each screening.
Why Master Your DCP in Korea?
If your film has already been graded and mixed in Korea, mastering the DCP at the same facility ensures continuity — the colorist who graded your film can verify the DCI-P3 conversion on the same calibrated display, and the sound team can confirm the audio packaging matches their final mix. This eliminates the "handoff error" that's common when DCP mastering happens at a different facility from the grade.
Even if your film was finished elsewhere, Korean facilities offer competitive DCP mastering with fast turnarounds. The combination of modern encoding hardware, DCI-compliant QC facilities, and experienced operators makes it a strong option — especially for productions already working with Korean teams on other aspects of post.

What DCP Actually Is
Digital Cinema Package (DCP) is the format for theatrical distribution. Unlike streaming deliverables, DCPs are designed specifically for cinema projection with strict technical specifications.
Picture: JPEG 2000 compressed, 12-bit X'Y'Z' color space, 2K (2048x1080) or 4K (4096x2160) resolution, 24fps or 25fps (48fps for specific HFR projects).
Audio: Uncompressed PCM in WAV files. Can be mono, stereo, 5.1, 7.1, or Dolby Atmos. 48kHz or 96kHz sample rate, 24-bit depth.
Subtitles: XML-based timed text, specific DCP subtitle format, per-reel organization.
Encryption: Optional but common for commercial theatrical. Encrypted DCPs require KDMs (Key Delivery Messages) per projection server. Unencrypted DCPs can play on any compliant projector.
Packaging: MXF-wrapped assets organized per reel. CPL and PKL files describe the composition and integrity. Typically delivered on hard drives or via secure file transfer.
DCI Compliance: Why It Matters
DCI (Digital Cinema Initiatives) is the consortium that defines the specifications for digital cinema. DCI-compliant projectors must support specific picture and audio formats, and DCPs must conform to these specifications to play reliably.
DCI compliance covers: specific color space (DCI-P3 with white point at 6300K), specific gamma (2.6), specific audio channel configurations, specific subtitle formatting, specific encryption schemes for protected content.
A DCP that fails DCI compliance may play incorrectly, fail to play, or cause projection errors. Experienced DCP mastering facilities verify DCI compliance throughout the mastering process, not just at final QC.
The Korean DCP Mastering Workflow
Korean DCP mastering facilities handle Korean theatrical releases routinely, with the major Korean cinema chains (CGV, Lotte Cinema, Megabox) all equipped for standard DCP distribution. Facilities serving these chains handle hundreds of DCPs annually, building institutional expertise in DCI compliance and theatrical delivery.
The typical mastering workflow:
Conform from final color. The color-graded master in Rec.709 or Rec.2020 gets converted to DCI-P3 color space with the theatrical luminance mapping applied. Korean colorists familiar with theatrical work handle this conversion with awareness of how the image will present in cinema projection.
Picture encoding. JPEG 2000 encoding at 250 Mbps for 2K or 500 Mbps for 4K, MXF wrapping, reel structure.
Audio integration. Theatrical audio mix imported, channel configuration verified, reference level set at -20 dBFS. Subtitle tracks integrated if required.
DCP assembly. CPL, PKL, and Asset Map files generated. Package integrity verified. Encryption applied if required, with KDM generation for specified projection servers.
QC. Automated DCI validation. Manual playback review on DCI-compliant projector. Loudness and technical compliance verified.
Delivery. Hard drive shipment or secure file transfer to cinemas, KDM distribution for encrypted content.
IMAX and Premium Large Format
IMAX has additional specifications beyond standard DCP: specific aspect ratios (1.43:1 for IMAX, 1.90:1 for IMAX Digital), enhanced audio specifications, and IMAX-specific color management. True IMAX releases require IMAX DMR (Digital Media Remastering) or similar premium-tier mastering that few facilities handle.
Premium Large Format (PLF) screens from Dolby Cinema, ScreenX, and others have their own specifications. Dolby Cinema requires Dolby Vision HDR theatrical delivery alongside standard DCP. ScreenX requires the distinctive three-wall presentation format.
Korean DCP mastering facilities handle standard DCP and most PLF formats. True IMAX DMR is typically handled by IMAX directly, not by third-party facilities. For projects with IMAX distribution ambitions, coordinate with IMAX's technical operations team directly.
Festival Submission DCPs
Film festival submissions have specific DCP requirements that vary by festival. Cannes, Sundance, TIFF, Berlin, and Venice each have their own technical specifications and preferred delivery methods.
Common festival requirements: unencrypted DCP (eliminates KDM coordination complexity), specific picture and audio formats, specific subtitle integration requirements (festival subtitles often override production subtitles), specific runtime and reel structure preferences.
Korean DCP mastering facilities with festival delivery experience know the specific requirements. For a festival-focused independent feature, an experienced Korean DCP facility delivers a festival-ready DCP at $2,500-$4,500, compared to $5,000-$9,000 for equivalent LA work.
Cost Breakdown for DCP Mastering
Representative pricing for a feature film DCP:
Korean facility: $1,500-$4,000 for 2K DCP, $2,500-$6,000 for 4K DCP. Includes picture encoding, audio integration, basic subtitle integration, DCI compliance verification, and physical drive or file delivery. Encrypted DCP with KDM generation adds $500-$1,500.
LA facility: $3,000-$8,000 for 2K, $5,000-$12,000 for 4K. Comparable services, higher rates.
For productions with multiple DCP versions (theatrical, festival, international territories with different subtitle requirements), costs scale with each additional version. Working with Korean facilities means each additional version costs less, making multi-territory theatrical distribution more economically feasible.
