Decimator 12G‑CROSS – 12G‑SDI / HDMI 2.0 4K Cross Converter with Advanced Scaling & Frame‑Rate Conversion

The Decimator 12G‑CROSS is a compact, ultra‑versatile 4K cross‑converter designed for professional broadcast, production and AV environments that demand maximum flexibility, format interoperability and rock‑solid reliability. Built in a robust aluminium enclosure with no fan, the 12G‑CROSS delivers silent, low‑power operation suitable for studios, OB vans, live events and field production.

Featuring a powerful 4K Motion Adaptive Scaling Engine, full 12G/6G/3G/HD/SD‑SDI support, HDMI 2.0, frame‑rate conversion, test pattern generation and a built‑in LCD control interface, the 12G‑CROSS is one of the most capable format converters in its class.

Scaling & Conversion Engine

The 12G‑CROSS performs:

• Up‑conversion (SD → HD → 4K)

• Down‑conversion (4K → HD/SD)

• Cross‑conversion (e.g., 1080i ↔ 1080p)

• Frame‑rate conversion (integer & fractional)

• Aspect ratio control

• Color space conversion (BT.709 ↔ BT.2020)

• Horizontal/vertical flip

• Motion‑adaptive 4K scaling

• Internal precision up to 32–40 bits for superior image quality

Total possible conversions:

• 20,007 (from website)

• 3,249 (from brochure’s 57-format engine) (Both numbers are correct depending on mode: full engine vs. 57‑format scaling engine.)
