ARRI ALEXA 35 Xtreme Review: High‑Speed Super 35 Cinema Camera (Up to 660 fps)

ALEXA 35 Xtreme takes everything productions love about ALEXA 35—REVEAL Color Science, LogC4, dependable ergonomics—and adds an all‑new high‑speed pipeline with ARRICORE. The result: the classic ARRI look, now with cinematic slow‑motion up to 660 fps.

Overview & Key Highlights

Sensor & DR: 4.6K Super 35 ALEV 4 with about 17 stops of latitude in standard modes.
High‑Speed: Up to 330 fps at full dynamic range; up to 660 fps using Sensor Overdrive (with reduced DR).
Codec: New ARRICORE RGB codec reduces data rates for high‑speed capture while preserving image quality.
Workflow: Same accessories, media (CODEX Compact Drives), menus, and REVEAL/LogC4 pipeline as ALEXA 35.
Use cases: Premium commercials, narrative action/beauty, VFX, macro/wildlife—where slow‑motion and color accuracy matter.

What’s New vs. ALEXA 35

High‑Speed Engine: 330 fps with full DR for “everyday” slow‑mo; Sensor Overdrive unlocks 660 fps for specialty moments.
ARRICORE Codec: Enables the extreme frame rates at lower data rates vs. traditional RGB pipelines, easing media/offload pressure.
Continuity: Same body family, accessories, and media, so rental houses and crews can integrate Xtreme without re‑training.

Image Science That Stays the Same (for Good Reason)

The Xtreme inherits ARRI’s REVEAL Color Science with LogC4, a low‑noise ALEV 4 sensor design, and nuanced highlight roll‑off. Expect predictable grading, robust skintones, and clean HDR‑friendly highlight handling compared to older generations.

High‑Speed Capture: Practical Notes

330 fps, full DR: Ideal for action, beauty pours, food/product work, and VFX plates where latitude matters.
660 fps, Sensor Overdrive: Signature “freeze‑time” aesthetic with ~11 stops DR (expect limits on shutter angle/EI and specific recording constraints).
Lighting: Confirm flicker‑safe fixtures at your shutter/fps; test HMIs/LED drivers at your mains frequency.
Data: ARRICORE reduces data rates, but slow‑mo still eats media. Budget offload speed, RAID throughput, and extra drives on heavy days.

Ergonomics, I/O & Power

Operators and ACs will feel at home: familiar ARRI UI, assignable buttons, MVF‑2/CCM‑1 support, and established power/mounting. Power draw rises with frame rate and monitoring; plan high‑current batteries and a smart distro for Xtreme days.

Codecs, Media & Data Strategy

ProRes family for most work; ARRICORE is added for the highest fps/Overdrive.
Media: CODEX Compact Drives continue—align card count with fps plan and DIT offload math.
DIT workflow: Maintain dual‑ingest checksum, manage ARRICORE decode paths in your apps, and organize per‑scene LUTs/looks.

Color, Monitoring & Post

LogC4 & REVEAL: Ensure current IDTs/LUTs in Resolve/Baselight/Colorfront, etc.
Village consistency: Keep LUTs unified across on‑cam and village monitors; avoid baking irreversible looks for editorial.
HDR deliveries: The extra latitude vs. older ALEXAs helps manage speculars and skintone roll‑off.

Where Xtreme Shines

Commercial beauty: Ultra‑clean slow‑mo with flattering skin.
Narrative action: 120–330 fps for expressive motion; 660 fps for tent‑pole beats.
Nature/macro: Reveals motion textures invisible at 24 fps.
VFX plates: Stable textures with consistent color management.

Watch‑Outs & Limitations

Sensor Overdrive trade‑offs: Lower DR (~11 stops), shutter angle limit, EI range constraints, ES mode restrictions—test with your lighting.
Throughput: Even with ARRICORE, high‑fps = heavy data. Budget DIT time, backup media, and batteries.
Super 35 sensor: If you specifically want LF DoF, plan lensing/composition to achieve it.

ALEXA 35 Xtreme vs ALEXA 35 (Standard)

Image: Same ALEXA 35 look (REVEAL/LogC4) and ~17‑stop latitude in normal modes.
Speed: Xtreme adds 330 fps full DR and 660 fps Overdrive—that’s the headline.
Workflow: ARRICORE joins ProRes; media/accessories remain familiar.

Recommended Kits & Accessories

Monitoring: MVF‑2/CCM‑1 on‑cam + calibrated village monitors; consider HDR‑aware chain on HDR shows.
Media & Offload: Extra CODEX drives + dual station checksum offload for slow‑mo days.
Power: High‑current Gold/V‑mount batteries; test real run‑times at target fps.
Lensing: Fast S35 cinema primes/zooms; for LF‑style separation, pick character lenses and compose accordingly.
