Comparison AI vs Human Video Production
Below is a real-world comparison for creating 10 one-minute videos per month, using AI tools vs hiring a human team.
Assumptions & Baselines
- Human production cost (mid-tier) ~ $1,000 per 1-minute video (includes filming, editing, voiceover, crew).
- AI approach uses subscriptions + minor human tweaks.
Cost Comparison Table
| Line Item | AI Scenario (InVideo + Synthesia + others) | Human Scenario | 
| Platform subscription | InVideo Max ($50) + Synthesia Creator ($89) + possibly Runway / DeepBrain add-ons = ≈ $150–$250/month | — (no subscription; cost is built into labor) | 
| Voiceover / narration | $0 (AI voice) or minimal cost for human voiceover | $200–$1,000+ (voice talent, studio recording) | 
| Editing, assembly, revisions | Mostly automated; maybe 3–10 hrs/month of oversight | 20–40+ hrs per video × 10 = major labor cost | 
| Filming / location / crew | $0 (no physical shooting) | Equipment, crew, travel, setup costs | 
| Total monthly cost estimate | ~$150–$600 depending on tool usage and human tweaks | ~$10,000 or more for 10 polished videos | 
| Cost per video | $15–$60 | ~$1,000 | 
Time & Effort: AI can produce 10 videos in hours or at most a day. A human team may take weeks to complete same content.
Final Recommendations
| Use Case | Best Tool / Mix | Recommendation | 
| Social / Marketing Ads | InVideo + Pika | Fast, templated output with creative overlays | 
| Training / Explainer / LMS | Synthesia or DeepBrain | Avatar-based, scalable, multilingual | 
| Cinematic / Branding Campaigns | Veo 3 / Leonardo / Kling AI | Use high-end outputs for hero content | 
| Hybrid Workflows / Editing | Runway | Use AI + manual edits to polish final versions | 
Best Practice: Start with one tool aligned to your primary need (e.g. marketing or training). Integrate it into your workflow, test with low-stakes content, then scale up. Always add human oversight (voice, script, review) when content has high brand or emotional weight.
