An AI video editor you prompt, versus one that invents footage
Veo, Kling and Luma generate frames that never existed. A prompted editor makes cutting decisions on footage you shot. Confusing the two is expensive.
Prompt-to-video means two unrelated things. One invents footage. The other decides how to cut the footage you already have. The first wins demos; the second is what gets posted on a Tuesday.
State of generation
- Veo 3.1 leads on prompt adherence and generates synchronised audio, including dialogue and ambience, in one pass.
- Runway has the strongest editing workflow layered on top of generation.
- Kling 3.0 handles ambitious physical motion better than the rest.
- Luma is strongest animating a reference image, with self-correction that cuts repeated regenerations.
- Sora's consumer app shut down on 26 April 2026, with the API scheduled to stop on 24 September 2026.
Where generation still breaks
The failure modes are consistent: hands, fast movement, face continuity across shots, and audio that does not match the scene. None of that matters in a showreel and all of it matters when the subject is supposed to be you. Generated footage also carries rights and brand-safety exposure that lands on the publisher, not the model.
What a prompted editor does instead
- You shoot one take on a phone and say what you want in a sentence.
- The model decides where to cut, what to drop, what to illustrate and where to place emphasis.
- Captions, music and b-roll are chosen against the meaning of what you actually said.
- Versions per platform come out of the same decision, not a separate export session.
The honest state of agents
Agentic editing works and is early. An agent can draft a script, build a shot list, call the services it needs and assemble a rough cut. Human review still decides taste, rights, brand safety, factual claims and pacing. Autonomous assembly and publish-ready production are not yet the same thing, and anyone claiming otherwise is selling the demo.
How to choose
| Need | Use |
|---|---|
| Footage that cannot be filmed | generation, with budget for regeneration |
| A daily cadence with your own face | a prompted editor |
| Cutaways inside your own clip | stock or short generated inserts, not a whole generated video |
| The same look for months | an agent with a fixed brand, not a generator with fresh output each run |
Where Monty sits
Monty is the prompted-editor side. One raw take in, a sentence about what you want, and out comes a finished vertical video: dead air and filler cut, captions synced to speech, music ducked under the voice, b-roll placed by meaning, audio cleaned, a version per platform, published to YouTube Shorts, Instagram Reels, TikTok and Telegram. It does not invent footage you never shot, and that limit is deliberate.
FAQ
What is the difference between generating and prompting an edit?
Generation invents frames. A prompted editor decides how to cut footage you shot, so your own face and voice stay in the result.
Which generator is best in 2026?
Veo 3.1 for prompt adherence and synchronised audio, Runway for the editing workflow, Kling 3.0 for physical motion, Luma for animating a reference image.
What happened to Sora?
The consumer app closed on 26 April 2026 and the API is scheduled to shut down on 24 September 2026.
Where does generated video reliably fail?
Hands, fast movement, face continuity between shots, and sound that does not match the scene.
Can an agent publish without review?
It can assemble without review. Publishing still needs a human for taste, rights, facts and pacing.
