Fields

DECKLINK_IOFEATURES_SUPPORTSRGB10BITCAPTURE = 1

Indicates that the DeckLink card supports capturing video in 10-bit RGB color format.

10-bit RGB capture provides enhanced color depth compared to standard 8-bit capture, offering 1024 levels per color channel instead of 256. This results in: - Smoother color gradients without banding - Better preservation of detail in highlights and shadows - Increased color accuracy for professional color grading

This feature is typically found on professional-grade DeckLink cards and is essential for high-end post-production workflows where color fidelity is critical.

DECKLINK_IOFEATURES_SUPPORTSRGB10BITPLAYBACK = 2

Indicates that the DeckLink card supports outputting video in 10-bit RGB color format.

10-bit RGB playback enables the output of high color depth video content, preserving the quality of professionally graded material. This feature ensures: - Accurate color reproduction on professional monitors - Smooth gradient display without banding artifacts - Full dynamic range preservation for HDR content

This capability is crucial for color-critical applications such as: - Color grading suites - Digital cinema mastering - Broadcast quality control

DECKLINK_IOFEATURES_SUPPORTSINTERNALKEY = 16

Indicates that the DeckLink card supports internal keying (alpha channel compositing).

Internal keying allows the DeckLink card to perform real-time compositing of video with alpha channel information directly on the hardware. This feature enables: - Real-time graphics overlay on live video - Transparent lower-thirds and titles - Hardware-accelerated compositing without CPU load

The key signal is derived from the alpha channel of the video signal being output, allowing for smooth, anti-aliased edges in composited graphics. This is particularly useful in live production and broadcast graphics applications.

DECKLINK_IOFEATURES_SUPPORTSEXTERNALKEY = 32

Indicates that the DeckLink card supports external keying using a separate key signal.

External keying uses a separate video signal (key or matte signal) to define transparency for compositing. This professional feature allows: - Use of dedicated key signals from graphics systems - Linear key support for high-quality compositing - Integration with professional vision mixers and switchers

The external key signal is typically provided through a separate SDI input and can be either a linear key (grayscale defining transparency levels) or a hard key (binary on/off). This feature is essential for broadcast facilities using external graphics generators.

DECKLINK_IOFEATURES_HASCOMPONENTVIDEOOUTPUT = 64

Indicates that the DeckLink card has component video output connectors.

Component video output provides analog video signals separated into three channels: - Y (luminance/brightness) - Pb/Cb (blue color difference) - Pr/Cr (red color difference)

This output type supports both standard definition and high definition formats and is commonly used for: - Connection to older professional monitors - Legacy broadcast equipment integration - Analog distribution systems

Component video provides better quality than composite video as it separates the color information, reducing color bleeding and improving overall image quality.

DECKLINK_IOFEATURES_HASCOMPOSITEVIDEOOUTPUT = 128

Indicates that the DeckLink card has composite video output connector.

Composite video combines all video information (luminance, chrominance, and sync) into a single analog signal. While lower quality than component or digital connections, it remains useful for: - Compatibility with consumer equipment - Legacy monitoring systems - Standard definition broadcast applications

Composite output typically uses RCA or BNC connectors and supports NTSC, PAL, and SECAM standards. The signal is limited to standard definition resolutions.

Component input supports both SD and HD formats including: - 480i/576i (standard definition) - 720p, 1080i, 1080p (high definition)

The higher quality of component video compared to composite makes it preferred for professional analog video capture when SDI is not available.

DECKLINK_IOFEATURES_HASCOMPOSITEVIDEOINPUT = 2048

Indicates that the DeckLink card has composite video input connector.

Composite video input enables capture from standard definition analog sources using a single cable connection. Common uses include: - VHS and other consumer format digitization - Security camera integration - Legacy equipment compatibility

While composite video quality is lower than component or digital formats due to combining all video information in one signal, it remains important for accessing content from older sources and maintaining compatibility with consumer equipment.
