How to make AI true crime videos
Last updated: May 2026 — 11 min read
What you'll learn
The end-to-end workflow for producing a cinematic AI true crime documentary — case selection, source-grounded research, narrative structure, narration register, visual treatment that respects victims, score, YouTube policy compliance, and monetization. Built around Onira's pipeline (Gemini 3.1 Pro screenplay, Pixverse v6 motion, ElevenLabs eleven_v3 narration, ElevenLabs Music score, Remotion assembly), but the principles apply to any production approach.

Atmospheric recreation, no victim imagery, measured narration
Why true crime is the right fit for AI production
True crime is one of the highest-engagement niches on YouTube — long session times, high watch-time-per-view, loyal subscriber audiences, and an unusually patient appetite for long-form. The constraint isn't audience demand. The constraint is production cost: traditional documentary research, scripting, voice talent, editing, and music licensing run $5,000–$50,000 per episode. For solo creators that math doesn't work at the cadence the algorithm rewards.
AI production collapses the cost. Onira ships a 20-minute case documentary in 10–20 minutes for roughly the credit cost of one Creator-plan month. That changes the unit economics enough to make a serious documentary channel viable as a one-person operation.
The catch: the genre is sensitive. Real victims, real families, real legal consequences. The rest of this guide is about how to use the production speed responsibly.
The six-step workflow
Each step matters. Skipping the research brief in step 2 is the most common mistake — it produces generic scripts that don't pass either YouTube's originality bar or the audience's accuracy bar.
Pick a case with documentation
Start with cases that have rigorous public-record documentation: court transcripts, official investigation reports, contemporaneous newspaper coverage, and reputable books. Cold cases from before 1990 and clearly closed historical cases are both legally lower-risk and content-richer because original source material has been catalogued by historians and journalists.
Build a research brief, not a prompt
Onira's Researcher agent does best with structured input. Write a brief: the case (dates, jurisdiction, principals), the angle (cold-case forensic, wrongful conviction, criminal-psychology profile, investigative-journalism deep dive), the sources (court records, books, articles, podcast episodes), and the narrative arc you want emphasized. The Showrunner agent uses this to curate facts and the Screenwriter produces the screenplay.
Choose narration register and language
ElevenLabs eleven_v3 ships dozens of voices across documentary, conversational, and dramatic registers. For true crime, lean toward measured documentary registers — Walter Cronkite, not Investigation Discovery. The pipeline supports 30+ languages, so the same case documentary can ship in English, Spanish, and German with localized narration without re-running the visual pipeline.
Let the pipeline produce the documentary
Once the brief is in, Onira runs end-to-end: research → screenplay → 60–80 scenes of cinematic visuals via Pixverse v6 → ElevenLabs narration → ElevenLabs Music score keyed to tension and resolution → Remotion final assembly with burn-in captions. Total turnaround is 10–20 minutes for most case lengths. The output is a finished MP4 — no editor required.
Review for accuracy before publishing
Onira's Verifier agent checks for internal script consistency. It is not a fact-checker. Before publishing, read the script — preferably alongside a domain expert (journalist, lawyer, historian) for sensitive cases. The pipeline produces what you asked it to produce; correctness is a function of the source material you brought.
Publish with proper YouTube policy compliance
Use YouTube's content disclosure tool to flag AI-altered content where required (current policy: required for content that makes a real person appear to do or say something they did not, or for realistic recreations of events that did not occur). Onira's atmospheric recreations are typically below the disclosure threshold — but check current policy at upload, not from a guide written months ago.
Ethics: the ground rules
Three rules that should not bend regardless of production tool.
- No victim imagery, no crime-scene photography. Onira does not generate it; you should not source it from elsewhere either. The case can be told without it. Audiences in the prestige tier explicitly reward restraint.
- Source from public record. Court documents, contemporaneous reporting, books with citations, academic case studies. Forum threads and unverified social posts are not source material.
- Identifiable living persons require legal review. Defamation and privacy law are jurisdiction-specific and unforgiving. Get a media-law attorney to review scripts before publishing content about people who could plausibly sue. Onira does not provide legal advice and the production speed is not a substitute for the review.
Monetization realities
True crime CPMs sit roughly in the $12–$25 range on YouTube — solid, not top-tier. History ($25–$40) and finance ($25–$50) are higher. The reason true crime monetizes well despite mid-tier CPMs is session time: a 25-minute documentary at 60% watch-through equals roughly 15 minutes of monetizable inventory per view, an outsized share of which is mid-roll.
Diversification matters. AdSense alone for a true crime channel typically tops out around $3,000–$8,000/month at 100K subscribers. Patreon supplementaries, sponsorship partnerships with adjacent products (security, legal services, identity protection), and affiliate revenue from book recommendations can double that without changing the production volume.

Frequently asked questions
Is AI-generated true crime allowed on YouTube?
Yes, with conditions. YouTube's policy evaluates whether content is original — original script, original visuals, original narration — not whether AI was used in production. Onira generates a unique script and unique cinematic visuals per video, and the eleven_v3 narration is original audio. Channels that use AI to create research-grounded, factually careful documentaries are not the target of the demonetization wave; mass-produced template content is.
How do I avoid sensationalizing real cases?
Two rules. First, source from public record — court documents, contemporaneous reporting, books and academic studies — not from forum speculation or unverified posts. Second, use measured narration. ElevenLabs eleven_v3 has a documentary register that reads as authoritative without being lurid; pick that voice and pace it down. The visual treatment should be atmospheric, not graphic — Onira does not generate crime-scene photography or victim imagery, which is the right default for the genre.
What's the legal exposure?
Defamation, invasion of privacy, and rights-of-publicity laws vary by jurisdiction and are particularly sensitive when content covers identifiable living persons or recent cases. Onira does not provide legal advice. Get a media-law attorney to review scripts before publishing content about living people, ongoing investigations, or recent cases. Historical cases (pre-1970s) and clearly closed cases are lower-risk; recent unsolved cases involving living persons are highest-risk.
How long should a true crime documentary be?
True crime audiences have unusually high tolerance for length. 15–30-minute case documentaries routinely outperform shorter clips on session time and watch-time-per-view, both of which feed the YouTube algorithm. Onira supports up to 30-minute productions; for most cases 18–25 minutes is the sweet spot — long enough to do justice to the investigation arc, tight enough to retain attention.
How much does it cost to produce?
On the Creator plan ($149/mo), 3,750 credits is the monthly allowance. A 10-minute production uses ~1,930 credits and a 30-minute production uses ~5,800. That's roughly two 10-minute episodes per month on Creator, or one full-length 30-minute case documentary plus top-up credits ($35 per 1,000 — they don't expire). For a weekly publishing schedule, the Studio plan ($349/mo, 9,500 credits) is the right entry point.
Can I dramatize cold cases without victim imagery?
Yes — that's exactly the workflow Onira is built for. The pipeline generates atmospheric recreations: period architecture, era-appropriate weather, anonymized silhouettes, environmental shots that suggest rather than depict. The narration carries the case detail; the visuals carry mood and continuity. This is the approach prestige true crime publishers (Serial, S-Town, HBO documentary series) take and it's the appropriate visual register for AI production.
