Content-dependent codecs (constant quality, VBR) vary their data rate with scene complexity — the figures above are typical values, and actual rates range around them.
Figures use decimal units (1 GB = 1000 MB), the convention used by drive and camera manufacturers. Computed with the same calculation engine as the Workflow Data Calculator — open it to add audio, streams, backup copies, offload time and storage cost, or to export a PDF report.
