Capacity-planning assumptions
Results use decimal storage units: 1 GB is 1,000 MB and 1 TB is 1,000 GB. Actual encoded bitrate can vary by scene, codec, quality settings, metadata, snapshots, filesystem overhead, retention policy, and provider behaviour. Keep operational reserve beyond the mathematical estimate.
