SyLC 3D Ultra-Player is not just another video player. It is the answer to a technological void that has frustrated 3D home cinema enthusiasts on PC for years.
While most modern players have abandoned true 3D in favor of compressed formats (SBS/TAB) or require complex, obsolete setups, SyLC was built with a single goal: To restore the glory of Blu-ray 3D (MVC) on Windows.
It natively reads H.264 MVC streams, decodes them in real-time, and sends them to your 3D projector or TV using the Frame Packing method, guaranteeing Full HD (1080p) quality for each eye.
The problem with standard players (VLC, MPC-HC, etc.) is that they only see part of the video stream. A 3D MKV file contains two streams:
- The Base View (AVC): The left eye, readable by everyone.
- The Dependent View (MVC): The right eye, encoded as a "difference" relative to the left.
Most players simply ignore the second stream. SyLC captures it, decodes it, and synchronizes it.
SyLC handles all formats, from the most basic to the most advanced:
| Mode | Description | Resolution per Eye | Verdict |
|---|---|---|---|
| 1. Side-by-Side (SBS) | Images placed next to each other. | 960 x 1080 | 50% loss of horizontal definition. |
| 2. Top-and-Bottom (TAB) | Images stacked vertically. | 1920 x 540 | 50% loss of vertical definition. |
| 3. FRAME PACKING 🌟 | The Holy Grail. | 1920 x 1080 | Pristine Blu-ray 3D Quality. |
Developing SyLC required overcoming major obstacles where standard libraries failed.
To achieve Frame Packing, we couldn't rely on off-the-shelf decoders. We had to rewrite and adapt a custom H.264 decoding core (based on edge264).
- Dual-Stream Extraction: Our engine simultaneously separates and processes the base view and the dependent view (MVC).
- Atomic Synchronization: Both views are reassembled with microsecond precision to avoid any "desync" effect or eye strain.
- Unified Buffer (Zero-Copy): To ensure fluidity (24fps / 60fps), images flow between the C++ decoder and the rendering interface without unnecessary memory copying.
This is where the magic happens. Frame Packing involves sending a "giant" image to the graphics card, containing both views separated by a silent band (active blanking).

SyLC generates this complex surface in real-time via custom OpenGL shaders, allowing your TV or projector to instantly recognize a native 3D signal.
- Auto-Detection: Intelligent analysis of metadata (MKV, MP4, M2TS) to activate the correct 3D mode.
- "Glassmorphism" UI: A modern interface that automatically fades away for total immersion.
- Smooth Timeline: Stabilized "seek" system with thumbnail previews (even in 3D mode!).
- Windows Optimized: Standalone, portable executable requiring no installation of shady external codecs.
- Bitstream Audio: Support for multi-channel audio tracks.
- Download the latest Release (
.exefile). - Run
SyLC_Player.exe. - Drag and drop your 3D video file.
To achieve the ultimate 3D quality (Frame Packing), follow these specific steps:
- Configure Output: Ensure your Projector/TV output resolution is set to 1920x2205 @ 24Hz (you may need to create a Custom Resolution in your NVIDIA/AMD control panel).
- Move Window: When the video starts, a "Tall" window will appear. Drag this window onto your projector/secondary screen.
- Go Fullscreen: Press 'F' (or double-click). The window will cover the entire 1920x2205 area, triggering the hardware 3D mode on your device.
- Put on your glasses! 👓
Note: For standard SBS or TAB modes, simply toggle fullscreen on any standard 1080p display.
