Correction Time Ratio

Correction Time Ratio measures the minutes an editor spends fixing AI-generated cuts, captions, or silence removal for every minute the tool saves. A tool that drafts a 10-minute cut in 90 seconds but requires 25 minutes of cleanup has a ratio above 1 and destroys margin on fixed-fee video retainers. Agencies should benchmark this ratio on the same representative brief across tools: run identical footage through Descript, Submagic, and Kapwing, then log correction minutes per accepted deliverable. The category description's warning applies directly: the productivity result is the measured change in accepted deliverables and labor, not a category-wide multiplier. A 2026 MIT Technology Review and Snowflake study found fewer than half of agent-generated insights lead to action, a reminder that automated output still needs human review before client delivery. Track correction time per deliverable, not per tool demo.
