Part 1. Introduction

A 4K UHD Blu-ray disc remains the gold standard for cinematic quality, but physical discs aren't always the most convenient way to browse a large collection. Many enthusiasts prefer accessing their library via Plex, Infuse (Apple TV), or Kodi.

However, simply copying files isn't enough. To ensure your media server triggers the correct HDR mode and Atmos audio without constant buffering, you need a professional Remuxing strategy. Whether you want a 1:1 bit-for-bit copy or a compressed version to save space, Yuhan 4K UHD Creator provides the tools to bridge the gap between your disc shelf and your digital server.

The Solution: Remuxing vs. Transcoding

• Remuxing (Lossless): This involves taking the exact video and audio streams from the disc and placing them into a modern digital container (like MKV or MP4). By using M2TS Pass-through, you ensure zero quality loss.
• Transcoding (Compression): This re-encodes the video to a lower bitrate. This is essential if your 100GB (BD100) discs are consuming too much space on your NAS or if your home Wi-Fi cannot handle a native 90Mbps stream.

Part 2. Why Yuhan Media Tools are Essential for Your Server

Standard converters often strip away the complex metadata layers of a 4K disc. Yuhan 4K UHD Creator acts as a professional-grade bridge for your digital library:

• Full M2TS Pass-through: Yuhan supports 1:1 M2TS Pass-through, preserving the original video stream, every high-fidelity audio track (Atmos, DTS:X), and all subtitle layers exactly as they exist on the disc.
• Metadata Integrity: When moving to digital containers, Yuhan ensures the HDR10+ and Dolby Vision flags are correctly mapped, preventing the "washed-out" look on your TV.
• Smart 4K Compression: If your storage is limited, Yuhan’s advanced transcoding engine can compress a 4K UHD Blu-ray into a more manageable size while maintaining 10-bit depth and visual brilliance.
• Multi-Platform Support: Whether you are using macOS (VideoToolBox) or Windows (NVIDIA/AMD/Intel), Yuhan utilizes full hardware acceleration to make remuxing and encoding incredibly fast.

Step-by-Step: Optimizing for Your Media Server

Before we start, we need to download and install Yuhan 4K UHD Creator. If your computer is Windows, you can click the button on the left below to download it. If your computer is Mac, please click the button on the right below to download it.

Step 1: Import M2ts Files

To create a 4K UHD Blu-ray, launch the software and select the 4K UHD tab from the top menu. You can import your video content by clicking Add Video to select M2TS files from the BDMV/Stream directory, or by simply dragging and dropping the files directly into the interface. Once the files have loaded, you can customize each entry by selecting your preferred audio tracks and subtitles.

Step 2: Video Settings (Optional)

Click the edit icon on the right side of the video to open the video settings window. Here, you can trim the video, set chapters, and if the video already includes chapter information, Yuhan 4K UHD Creator will automatically import them.

Step 3: Choose a menu template and customize it

Navigate to the menu editor by clicking the Select Menu button. From here, you can browse the templates on the right to choose a theme and begin your customization.

Menu Customization Features

• Scene Capacity: Themes vary in layout, supporting between 3 and 10 scenes per page.
• Display Modes: You can toggle scenes to appear as thumbnails or as a text-based list.
• Interface Control: For a more minimalist look, you have the option to remove thumbnails, the "Scenes" button, or the "Setup" button from the main menu.

Step 4: Advanced Settings

In the software settings window, you can configure the UHD processing mode: pass-through or transcoding; video decoder and encoder, etc.

Step 5: Output Settings

You can export your project as a BDMV folder, an ISO image, or burn it directly to a physical disc. For a more streamlined viewing experience, you also have the option to pre-select default audio tracks and subtitles.

Step 6: Start authoring

Once all settings and customizations are finalized, click the 'Start' button to begin encoding your Ultra HD Blu-ray project. Thanks to GPU Hardware Acceleration, Yuhan can process 4K HEVC footage up to 10x faster than traditional encoders. Click "Start" to begin authoring your ISO file or burning directly to a BD25/BD50 disc.

Part 3. Plex & Infuse Compatibility FAQ

Q1: Why does my 4K movie look "washed out" on Plex?

This usually happens when the server is forced to transcode HDR to SDR because the file format is incorrect. By using Yuhan to properly remux the file into a compatible HEVC structure, you enable "Direct Play," which preserves the original HDR colors.

Q2: Can I keep multiple subtitle tracks in a digital remux?

Yes. The M2TS Pass-through feature in Yuhan 4K UHD Creator allows you to include every original audio stream and PGS subtitle track in your digital remux.

Q3: Does this work with the Apple TV 4K?

Yes. While the Apple TV is picky about formats, using Yuhan to create a high-bitrate MP4 with HEVC ensures that apps like Infuse can play your 4K rips with full Dolby Vision support.

Q4: How do I reduce the file size without losing 4K quality?

Use Yuhan’s "Smart Transcoding" mode. By targeting a bitrate of 50-60 Mbps (down from the original 90 Mbps), you can save 40% of your storage space with virtually no visible difference in image quality.

Q5: My 4K Blu-ray is 90GB, but my NAS is nearly full. What can I do?

You can use Yuhan’s Transcoding feature to compress the 4K UHD Blu-ray. By re-encoding the HEVC stream at a slightly lower bitrate, you can significantly reduce the file size while preserving 4K resolution and dynamic HDR metadata.

Part 4. Conclusion

Building a high-end digital library doesn't mean you have to sacrifice the quality of your physical collection. With Yuhan 4K UHD Creator, you get the best of both worlds: the uncompromised fidelity of 4K UHD Blu-ray and the instant accessibility of a digital media server.
