WHAT HASN’T CHANGED

Body & Accessories

Same housing, I/O ports, connectors, and layout as the standard ALEXA 35, just a new “Xtreme” decal. Everything fits right in, no need to swap rigs.

Resolution & Baseline Frame Rates

The existing popular recording formats, resolutions, and frame rates remain available.

Menu Interface

The UI, navigation structure, and on-screen controls are unchanged, just some new options for the additional frame rates and ARRICORE.

**WHAT HAS CHANGED**

ARRICORE Codec

A new, leaner RGB codec that slots between ARRIRAW and ProRes in file size. It’s optimized for high frame rates and cuts data rates by 50% compared to ARRIRAW without compromising image quality.
Offers post flexibility: EI sensitivity, white balance, and tint remain adjustable in post.
It’s a lower data burden, with the same workflow DITs have been using. Same wrappers, textures, and metadata handling you already know.

High Frame Rates & Sensor Overdrive Mode

Higher speed ceiling: Max frame rates are up across the board up to 330 fps while maintaining full 17-stop dynamic range.
Sensor Overdrive: doubles the ceiling to 660 fps, at the expense of dynamic range (~11 stops) and raising base ISO to EI 1600.
Example increases in real modes:
- 4.6K Open Gate: from 75 fps → 120 fps standard, 165 fps in Overdrive
- 3.8K 16:9: from 120 fps → 150 fps standard, 240 fps Overdrive
- 3.8K 2.39:1: newly available; captures up to 240 fps at full DR
- 2K 16:9 S16: up to 330 fps standard, 660 fps Overdrive
All high-speed recording require the 2TB Codex Compact Drive media instead of the 1TB.

Other Upgrades

10% reduced power consumption. Longer battery life, less heat output.
Pre-record buffer is 5× longer: up to 30 seconds in 4.6K Open Gate (ProRes 4444), or 5 minutes in HD (ProRes 422 HQ) at 24 fps.
Improved Wi-Fi: now supports the 5GHz band, mesh roaming, and auto-reconnect for tools like Camera Companion. To take advantage of this longer upgraded antenna are included.
