Professional 6G‑SDI capture and playback card with 10‑bit SD, HD, 2K and Ultra HD support, embedded multichannel audio, reference input and RS‑422 control. Ideal for editing, grading, graphics, broadcast and 4K production workflows.
DeckLink SDI 4K is a compact, high‑performance SDI capture and playback card designed for professional broadcast, post‑production and live graphics environments that require exceptional image quality and absolute reliability. Built around a 6G‑SDI pipeline, the card supports SD, HD, 2K and Ultra HD up to 2160p30, allowing seamless integration into modern multi‑resolution workflows. Its multi‑rate SDI connections switch automatically between formats, enabling direct connection to a wide range of cameras, decks, routers and broadcast hardware without the need for external converters.
The card delivers high‑precision 10‑bit SDI capture and playout, supporting both 4:2:2 and 4:4:4 color spaces for clean, accurate and broadcast‑ready imagery. It is engineered for demanding tasks such as editing, compositing, color grading, motion graphics and real‑time playback on professional production servers. With embedded audio support for up to sixteen channels in HD, 2K and 4K and eight channels in SD, the DeckLink SDI 4K ensures perfect audio‑video synchronization across complex production pipelines.
For workflows requiring precise timing, the card includes a Tri‑Sync or Black Burst reference input, ensuring rock‑solid synchronization in multi‑device environments. RS‑422 deck control provides accurate machine control for ingest, batch capture and mastering from professional VTRs. The card’s compact PCI Express Gen 2 x4 design ensures high bandwidth and low latency on macOS, Windows and Linux systems while maintaining compatibility with a wide array of professional software including DaVinci Resolve, Adobe Premiere Pro, Avid Media Composer, Fusion, After Effects and numerous live production and broadcast automation tools.
Featuring support for industry‑standard codecs such as ProRes, DNxHD, DNxHR, XDCAM, DPX, AVC‑Intra and uncompressed 8‑bit and 10‑bit formats, DeckLink SDI 4K integrates cleanly into both compressed and uncompressed post‑production pipelines. Internal keying support allows live graphics overlay directly through the card, making it suitable for broadcast graphics, titling and playout servers. Designed as one of the world’s smallest and most affordable SDI‑only 4K capture cards, DeckLink SDI 4K delivers powerful performance in a streamlined form factor ideal for studios, mobile broadcast units and high‑density render systems.
