Atomos just announced RAW recording at up to 4K@60Hz via HDMI from Sony’s new Alpha 7S III (ILCE-7SM3) full-frame mirrorless camera to the Ninja V HDR monitor-recorder. The Alpha 7S III has a CMOS image sensor, and the Ninja V can record its full dynamic range in Apple ProRes RAW for maximum detail and latitude in post-production. The active cooling employed means that internal record time limitations can be bypassed. Optionally, RAW video can also be captured on the Ninja V while compressed video is recorded internally to memory card on the Alpha 7S III, providing several workflow options and a useful backup.

Data from the Alpha 7S III’s large photosites makes recording RAW in dim conditions a practical option. The Alpha 7S III also has five-axis optical image stabilization available while shooting RAW video.

The 16-bit linear RAW output of the Alpha 7S III is compressed and recorded in the Ninja V as 12-bit ProRes RAW at up to 4K@60Hz. The result is a high-quality ProRes RAW file that combines the visual quality of the Alpha 7S III with the workflow advantages of RAW and ProRes’ real-time performance. One key benefit, especially in low light, is that the ProRes RAW files allow you to take fine control of how noise reduction and sharpening is applied to images, tuning these precisely for each shot.

According to Atomos, for the first time in a mirrorless camera from Sony, a 10-bit 422 HDMI video output option is available. The Ninja V and other current Atomos monitor-recorders can record this as 10-bit 422 Log or Rec.709 video at up to 4K@60HZ into production-ready ProRes or DNx codecs. These provide long record times and practical data rates when the additional flexibility of RAW is not required. This is ideal for situations where the camera needs to integrate into an established post workflow, or a fast turnaround is needed.

The 5” 1000nit HDR high brightness display of the Ninja V allows users to view the Alpha 7S III RAW signal in HDR in a choice of HLG and PQ (HDR10) formats or view natively in Sony’s S-Log profile and used with LUTs. The monitor offers touch screen access to tools like waveform, magnification and peaking so users can check focus and make adjustments to get the perfect HDR or SDR shot.
