                          CAPTURE ENGINE - WIKI

=============================================================== 

OVERVIEW

--------

The Capture Engine is a high-performance screen, region, and audio recording 

utility designed for Windows. Built heavily on DirectX (D3D11/D3D12), Windows 

Media Foundation, WASAPI, and FFmpeg, it focuses on near-lossless, zero-drop 

recording using advanced hardware acceleration and deep memory buffering.

FEATURES

--------

* High-Performance Capture: Utilizes DirectX Desktop Duplication API for 

  zero-latency screen capture.

* Hardware Encoding: Natively leverages NVIDIA NVENC, AMD AMF, and Intel QSV

  for H.264, H.265 (HEVC), and AV1 hardware encoding.

* High Color Fidelity: Supports 4:4:4 chroma subsampling (YUV444P) and 

  high-quality Lanczos scaling for perfect visual quality and text clarity.

* Multi-Source Input: Capture full screen, custom regions, USB Video Devices 

  (webcams/capture cards), and IP Camera streams (RTSP/HTTP).

* Advanced Audio: Multi-track WASAPI system audio and USB microphone capture.

* Burst Buffering: Uses large RAM buffers and memory locking (Large Pages) to 

  absorb high-bitrate I/O spikes and prevent frame drops during NVMe writes.

* Cross-Adapter Support: Seamlessly handles setups where capture and encoding 

  occur on different GPUs.

SYSTEM REQUIREMENTS

-------------------

To ensure a smooth, drop-free recording experience, especially at 4K or 

high frame rates (120+ FPS), the following minimum and recommended hardware 

specifications apply.

MINIMUM REQUIREMENTS

* Operating System: Windows 10 (64-bit) or later.

* CPU: Intel Core i5 (6th Gen) or AMD Ryzen 5 (1st Gen).

* RAM: 8 GB DDR4.

* GPU: Dedicated GPU with hardware video encoding support 

  (NVIDIA GTX 900 series, AMD RX 400 series, or Intel UHD Graphics 600).

* Storage: SSD with at least 500 MB/s write speed.

* DirectX: DirectX 11 or 12 compatible hardware.

RECOMMENDED REQUIREMENTS (For 4K / High FPS / Near-Lossless)

* Operating System: Windows 11 (64-bit).

* CPU: Intel Core i7 (10th Gen) or AMD Ryzen 7 (3000 series) or better.

* RAM: 16 GB DDR4/DDR5 (Highly recommended to allow large RAM burst buffers).

* GPU: NVIDIA RTX 2000 series or newer (for advanced NVENC HEVC/AV1 encoding),

       AMD RX 6000 series, or Intel Arc. 

* VRAM: 6 GB or more dedicated Video RAM.i5

* Storage: NVMe M.2 SSD with 3,000+ MB/s sustained write speeds.

NOTES FOR ENABLING ADVANCED FEATURES

------------------------------------

* Microsoft Store Compatibility: Configuration and log files are safely saved

  to the user's `%LocalAppData%\RecordingEngine` folder.

* Large Pages Support: The application requests 'Lock Pages in Memory' 

  privileges to use Large Pages, which vastly improves heavy I/O performance. 

  (Requires running the application as Administrator or adjusting local security policies).
