Cost Model By Video Minute

This document captures the reproducible planning baseline for performance plan item Cost model by video minute.

What this model is:

  • A benchmark-backed planning model for cost per source-video minute.
  • Derived from the checked-in FFmpeg runtime baseline and object-storage bandwidth baseline.
  • Based on explicit example cost assumptions that are intended to be replaced with current vendor-specific prices during rollout.

What this model is not:

  • It is not live cloud pricing.
  • It is not a production invoice forecast.
  • It does not include cross-region egress, observability platform costs, database costs, or support overhead.

How to rerun:

mvn -q -Dtest=CostModelBenchmarkHarness test

Generated artifact:

  • target/benchmarks/cost-model-by-video-minute.md

Interpretation notes:

  • compute reflects FFmpeg worker time from the preset benchmark.
  • transfer reflects worker time spent waiting on object-storage throughput assumptions.
  • retention scales with source and output bitrate assumptions plus retention days.
  • requests captures one source GET plus clip PUT activity and remains a minor component in the modeled scenarios.

Operational note:

  • Replace the example hourly and storage rates with current prices from the target cloud before using this model for budgeting or margin decisions.
