HEVC codec with high compression efficiency
XAVC HS format recording, using the MPEG-H HEVC/H.265 codec, roughly doubles the compression efficiency. Compared to a normal 4K XAVC S format, XAVC HS allows for detailed 10-bit video with 4:2:2 colour sampling at comparable or lower data rates, delivering even better image quality as well as manageable file sizes.
16-bit RAW data output
Facilitating improved image quality and more flexible and efficient editing in post production, the FX3 supports 16-bit RAW data output to an external recorder via the HDMI Type-A terminal. RAW video output is from a full-frame image sensor with 4264 x 2408 [16:9] resolution, to suit 4K (QFHD) or DCI-4K workflows, with a choice of frame rates (59.94p/50p/29.97p/25p/23.98p).
S-Log2 and S-Log3 with 10-bit 4:2:2 support
S-Log2 and S-Log3 gamma curves are available, with S-Log3 giving better gradations from shadows to the mid-grey range (18% grey), enabling a dynamic range of up to 15+ stops. For camera matching with other S-Log3 capable Cinema Line cameras, three colour gamut settings (S-Gamut, S-Gamut3, and S-Gamut3.Cine) are available, offering creative flexibility and efficiency during post production.
Proxy recording for more efficient editing workflow
Low bit-rate HD proxy files can be recorded simultaneously with higher bit-rate formats such as XAVC S-I 4K, and these smaller proxy files can then be used for editing and previewing prior to final production delivery. This reduces computer load and allows faster and more efficient workflows. Proxy files can be captured in either 10-bit XAVC HS (1920 x 1080) or 8-bit XAVC S (1280 x 720) .
Expand your vision with Creative Look
Looks emulate pro monitoring and post-production tools inside the camera. The Creative Look presets are available in-camera, and each of these can be used as is, or further customised using individual parameter settings such as hue, colour depth, brightness, contrast, and sharpness. Fine adjustment of preset looks can be made according to the user's preference, and you can also register your favourite settings as a custom look.
10-bit HLG picture profile
An HLG (Hybrid Log-Gamma) HDR picture profile, complete with the wide-gamut BT.2020 colour space, can be used for direct HDR (HLG) playback on compatible TVs. The result is true-to-life imagery close to what the naked eye can see, with detailed shadows and highlights, less blackout and less whiteout, all without the need for colour grading. In particular, 10-bit recordings reproduce a level of fine gradation and detail for extraordinary realism.  High flexibility to fine-tune images as desired (colour grading required)  Instant high-quality image (colour grading not required)
