4K UHD Blu-ray Authoring Service

Core Encoding & Dynamic HDR Processing

• HDR10 Encoding

  Compliant with SMPTE ST 2086 static HDR metadata standard, supports master display color volume, max/min luminance & light level metadata embedding. Optimized for 10-bit 4:2:0/4:2:2 HEVC (H.265) encoding, full Rec.2020 wide gamut color space mapping, frame-level bitrate profiling for UHD disc playback compatibility across standalone players and smart TV systems.

• HDR10+ Encoding

  Implements SMPTE ST 2094-40 dynamic metadata specification. Frame-by-frame scene adaptive brightness & tone mapping, eliminates highlight clipping and shadow crushing. Supports metadata injection during real-time encoding and post-encoding remuxing; fully backward compatible with HDR10 devices, certified for mainstream UHD playback hardware.

• Dolby Vision Encoding

  End-to-end Dolby Vision workflow including CM 4.0/5.0 mastering, dynamic metadata generation (MLA/MLL), L1/L2 metadata grading and embedding. Supports dual-layer EL/BL stream structure for UHD Blu-ray, complies with Dolby UHD Blu-ray technical specifications. Enables scene-by-scene dynamic tone mapping, precise color grading retention for professional film & video content.

UHD Blu-ray Disc Format & Layer Configuration

• UHD 66GB (3-Layer)

  Triple-layer Ultra HD Blu-ray disc standard (BD-66), official physical format compliant with Blu-ray Disc Association (BDA) UHD specifications. Optimized data layer spacing & error correction coding (ECC), stable bitstream for high-bitrate 4K content; ideal for feature films with multi-audio/subtitle tracks and basic menu assets.

• UHD 100GB (4-Layer)

  Quad-layer UHD Blu-ray disc (BD-100), maximum capacity consumer UHD optical disc format. Enhanced scratch resistance & data integrity protocols, supports ultra-long runtime content, high-bitrate video, lossless multi-channel audio and complex animated menu packages.

Full UHD Blu-ray Authoring & Menu Development

  Complete disc project assembly: playlist creation, chapter point marking, timeline linking, playback rule configuration, parental lock, region code & playback restriction settings. Strict adherence to BDA UHD BD-ROM file system, UDF 2.5/2.6 file system standard, seamless disc emulation & pre-master verification before output.

• Menu Development Suite

  • Still Menu: Static 4K resolution menu assets (3840×2160), 10-bit Rec.2020 color, alpha channel transparency support, button mapping, highlight/select state design & interactive logic setup.

  • Animation Menu: Motion graphic 4K animated menus, frame-accurate video loops, transition effects, audio sync for menu motion, layered interactive button programming, compliant with UHD BD playback frame rate rules (23.976/24/25/29.97/30fps).

• UHD CMF Output

  Generate industry-standard Cutting Master Format (CMF) for UHD Blu-ray replication. Includes complete disc image,  checksum verification, replication-ready metadata, layer break configuration and professional pre-press deliverables for mass disc production.

Multi-Track Audio & Subtitle Processing

• 20+ Audio Tracks Support

  Full support for multi-format audio tracks: Dolby Atmos, Dolby TrueHD, DTS:X, DTS-HD Master Audio, LPCM, Dolby Digital Plus, DTS Digital Surround. Manage up to 20+ discrete audio tracks (multi-language, commentary, alternate mixes), track naming, language tagging, default track assignment and seamless audio switching during playback. All audio streams optimized for UHD Blu-ray bitrate limits and player decoding compatibility.

• 20+ Subtitle Tracks Support

  Process 20+ subtitle streams (multi-language, forced subtitles, commentary subtitles). Support PGS (Presentation Graphics Stream) native UHD Blu-ray subtitle format, 4K subtitle rasterization, subtitle timing sync, position adjustment, font styling, forced subtitle flagging, subtitle on/off control and chapter-linked subtitle rules. Compatible with all region UHD players.
