# Calculating ROIROIReturn on Investment: the ratio of net profit to the cost of an investment. A 300% ROI means each dollar invested returns $3.View full definition → on AI production tools
A mid-sized post-production house in London runs the same trailer edit twice: once the traditional way, once with an AI-assisted rough-cut tool. The AI version comes in 40% faster. Six weeks later, the client requests three additional rounds of revisions because the pacing "feels off" in two scenes the AI selected. The editor who reviews this cut later calls it "fast, but not free." That tension between speed gained and quality re-work owed is the entire ROIROIReturn on Investment: the ratio of net profit to the cost of an investment.

Vendors selling AI rough-cut tools (Adobe Premiere's AI features, Runway, Descript, or specialized tools like Munch or Move.ai for other pipelinepipelineAll active sales opportunities across the stages of the sales process, together with their combined potential value and probability of closing.View full definition → stages) love to quote time savings. A common vendor claim: AI can cut initial assembly time by 30 to 50% (industry estimate, varies widely by content type and tool, as of 2025).
That number is real but incomplete. It measures input time, not output value. A defensible ROIROIReturn on Investment: the ratio of net profit to the cost of an investment. A 300% ROI means each dollar invested returns $3.View full definition → case has to net out three things:
1. Hours saved on the task the AI touches directly.
2. Re-work cost when AI output needs human correction, beyond normal review.
3. Quality tradeoff cost, harder to quantify: lost nuance, tone misses, or brand risk that surfaces after delivery.
Here is the core calculation, adapted for production tooling rather than generic finance:
Net Hours Saved = (Baseline Hours - AI-Assisted Hours) - Re-work Hours
ROI (%) = [(Value of Net Hours Saved - Tool Cost) / Tool Cost] x 100Where "Value of Net Hours Saved" = Net Hours Saved x fully loaded hourly rate of the editor or team.
Assume a post-production house in the US handles 20 trailer edits per month.
Step 1: Raw hours saved per trailer
8, 5 = 3 hours saved
Step 2: Adjust for re-work
40% of 20 trailers = 8 trailers need 1.5 extra hours = 12 hours/month of re-work
Step 3: Net hours saved per month
(3 hours x 20 trailers) - 12 hours = 60, 12 = 48 net hours saved/month
Step 4: Dollar value
48 hours x $75/hour = $3,600/month in labor value recovered
Step 5: Net of tool cost
$3,600 - $250 - $167 = $3,183/month net benefit
Step 6: ROI

That number looks spectacular, and it can be real. But it only holds if the re-work estimate is honest. Many early adopters under-report re-work because it happens downstream (client revision rounds) rather than in the edit bay, where it's easy to see.
Re-work hours are visible and billable. Quality tradeoffs are not, and they show up as:

1. Why do vendor claims about 'hours saved' on AI production tools give an incomplete picture of ROI?
2. In the Net Hours Saved formula, what role does 're-work hours' play?
3. A studio finds that an AI tool cuts assembly time by 45%, matching vendor claims, but editors report spending extra time each week fixing pacing issues in AI-selected cuts. What should the studio do before concluding the tool has strong ROI?

1. Comparing AI cost to zero cost. The real comparison is AI cost versus the fully loaded cost of the human hours it replaces or augments, not versus doing nothing.
2. Ignoring ramp time. Editors take 4 to 8 weeks (estimate) to get efficient with a new tool. Early ROIROIReturn on Investment: the ratio of net profit to the cost of an investment.

3. Skipping the re-work audit. If nobody is tracking how many AI cuts get sent back for revision, the number is fiction.
4. Treating all content types the same. A 30-second social cutdown tolerates more AI-driven imprecision than a theatrical trailer.
