Recording parameters
Sumo 19: up to four simultaneous 1080p60 ISO feeds via 3G-SDI Level A. The 4 ISO option multiplies the per-feed storage estimate by four.
Typical reference bitrate. Actual rate varies by implementation and frame rate.

Atomos Sumo 19 • 1 feed
Storage is calculated for the selected number of simultaneous recorded feeds.
Apple ProRes 422
Estimated reference bitrate based on raster and frame rate.
—
This is an estimate. Use Custom bitrate for a known encoder setting.

Based on selected channels, sample rate and bit depth.
Equipment profile: Sumo 19 and HyperDeck Studio 4K Pro.
Both support ProRes 422 workflows, but exact recordable formats depend on the selected raster and frame rate.
SDI transport bandwidth and recording bitrate are separate calculations.
Engineering note: ProRes rates use the configured raster-specific 29.97 fps reference table and scale by frame rate; the default workflow is 1080p50. ProRes is VBR, so actual files vary around the target; validate the exact recorder profile and allow storage headroom.
