"Worksheet","Plan multicamera recording capacity and playback rate separately","Evidence status","Your configuration"
"Purpose","Add simultaneous camera rates for throughput, and multiply each rate by its recording duration for capacity. Spare terabytes do not establish enough sustained read or write performance.","Proposed workflow",""
"Check","Question to record","Decision","Your observation"
"Capacity","Rate × time for each source","How much storage",""
"Throughput","Sum of simultaneous rates","How quickly data must move",""
"Decoding","Codec, profile and hardware route","Whether playback remains responsive",""
"Example","Four hypothetical cameras at 100 Mbps each require 400 Mbps, or 50 MB/s, of compressed video data when read simultaneously. Each hour produces about 45 GB per camera, or 180 GB total before audio, overhead and reserve. Those numbers do not certify a drive’s sustained behavior or the editor’s decoding speed.","Illustrative; not a measured product result",""
