![]() ![]() Simply put, a video capture card is a device that receives video from one source via HDMI (typically a gaming console or PC) and sends the same video out to a monitor or TV (also via HDMI). We will explain why you probably need a capture card despite your device being already capable of streaming. ~800MB/s per channel DMA bandwidth in PCIe 1.If you’re a gamer or streamer who has been wondering what a capture card can do for you or why you would purchase one if your Xbox/PlayStation/PC has the ability to stream on its own, keep reading this article. ~1600MB/s per channel DMA bandwidth in PCIe 2.x system Hardware clock can be synchronized across cards (via SDK) Hardware based 100ns high resolution clockĪudio frames (192 audio samples) & video frames are stamped with hardware clock Independent cropping, aspect ratio, color format, resolution, frame rate, de-interlacing and color adjustment settings for each individual stream Unlimited capture streams for any one input channel The video and audio device names displayed in your software will include the card number (set by the rotary switch) System hardware device tree will display “01: Pro Capture Dual HDMI 4K+ LT” when rotary switch is set to 1, and so on On-board rotary switch to set card number, with 16 positions from 0 to F Support for multiple cards plugged to one system Video OSD composition (support for PNG OSD image up to 4096×2160 support for dynamic loading of RGBA OSD image via SDK) ![]() Video color format conversion (auto or manual selection of input color format & quantization range auto or manual selection of output color format, quantization range & saturation range support for RGB, YCbCr 601, YCbCr 709, YCbCr 2020 color formats support for Limited or Full quantization range support for Limited, Full & ‘Extended gamut’ saturation range) Video aspect ratio conversion (Auto or manual selection of input aspect ratio Auto or manual selection of capture aspect ratio Three aspect ratio conversion modes: Ignore (Anamorphic), Cropping or Padding (Letterbox or Pillarbox)) Video de-interlacing (Weave, Blend top & bottom field, Top field only, Bottom field only) Two video processing pipelines with ~720Mpixels/s processing bandwidth each More capture formats are supported via Pro Capture SDK for DirectKS Support for capture frame rates up to 144fps (actual capture frame rate may be limited by PCIe bandwidth and image resolution)Ĥ:4:4 8-bit (V308, IYU2, V408, BGR24, BGR32) ![]() Support for capture image resolutions up to 4096×2160 pixels Support for Side-by-Side Half, Top-and-Bottom, Frame Packing 3D mode Support for extraction of Sony/Canon DSLR time code Support for extraction of 3D format information Support for extraction of video timing information Support for extraction of audio formation information & channel status data Support for up to 8-channel IEC60958/IEC61937 audio streams Support for RGB 4:4:4, YCbCr 4:4:4, YCbCr 4:2:2 color sampling Support for extraction of AVI/Audio/SPD/MS/VS/ACP/ISRC1/ISRC2/Gamut InfoFrames Support for input video resolutions up to 4096×2160 pixels Windows: DirectShow, DirectKS, Wave API/DirectSound/WASAPI (See “Related Products” for additional models with different input connectivity).įPGA-based video processing provides high-quality up/down/cross-conversion, de-interlacing, color space conversion, graphic overlay and more without taking host system CPU cycles away from third-party software - already significant because of the quadrupled processing requirements of 4K video compared to HD, and doubly beneficial when processing two 4K sources at once. HDMI loop-through connections reduce workflow costs and complexity by enabling source signals to be sent simultaneously to additional displays or equipment without the need for external splitters or routers. The Pro Capture Dual HDMI 4K Plus LT captures two channels of 4K video at up to 60 frames per second over HDMI 2.0 interfaces, with independent control of capture resolution, frame rate and video processing settings for each input. Magewell’s feature-rich yet cost-effective Pro Capture 4K PCI Express capture cards deliver outstanding performance, quality and reliability for bringing Ultra HD video and audio signals into all popular software for applications including live streaming, encoding, collaboration, videoconferencing, gaming, virtual reality (VR) production, medical imaging and archiving.
