Begin with either a finished audio performance or a script that can be converted into speech. Review the resulting transcript, place jump cuts where the delivery should change, and then build the visual performance around that audio. Select an existing actor, generate one from a written description, or upload a suitable character image. Define the setting through a background description or image, then audition multiple actors against the same material. This separates message development, voice delivery, casting, and visual production into controllable stages. The output is reusable A-roll that can stand alone for simple short-form content or feed a broader editing workflow containing product footage, captions, graphics, and B-roll.

Core principles
- 01Start with the intended spoken delivery, not the visuals.
- 02Treat AI actors as castable performers rather than fixed templates.
- 03Control backgrounds, cuts, and presentation before rendering.
- 04Use generated video to remove recording and production barriers.
How to run it
- 1
Prepare the message
Write a concise script or record the desired performance as audio. Optimize the message for the target format before generating visuals.
Pro tip Upload performed audio when precise pacing and emotion matter.
Watch out A generic script will remain generic even when the video looks realistic.
- 2
Load the delivery
Upload the audio or generate a voice from the script using an available voice provider.
Pro tip Choose a voice whose energy and cadence fit the intended actor.
Watch out Do not treat voice selection as an afterthought; it anchors the performance.
- 3
Review the transcript
Check the transcript and position jump cuts or delivery breaks where the video should change rhythm.
Pro tip Use cuts to remove dead space and sustain short-form pacing.
Watch out Poorly placed cuts can make an otherwise realistic performance feel artificial.

Create the visual setup
Select or generate an actor, then define the clothing, location, lighting, and background.
Pro tip Describe the desired actor and environment as specifically as a casting and set brief.
Watch out If using a reference image, ensure important facial details are visible.
- 5
Audition alternatives
Generate several actor options performing the same material and compare their fit with the message.
Pro tip Judge credibility, delivery, visual continuity, and brand fit together.
Watch out Do not select an actor solely because the still image looks attractive.
- 6
Render and review
Generate the selected performance and inspect every line, gesture, cut, and expression before publishing or editing further.
Pro tip Save the chosen actor for consistent future content.
Watch out A one-shot render may be usable, but it is rarely the strongest available result.
In the wild
A software marketer writes a 60-second explanation of a customer-support feature, generates a confident voice, auditions three professional-looking actors, and selects a simple office background. After adjusting two jump cuts, the marketer renders a vertical talking-head video for the product page.
→ The company gains a credible product explainer in hours without organizing a shoot.
The Captions team generated realistic presenters in a customized Japanese-inspired studio and used them to explain Mirage's value for ads, product demos, explainers, and landing pages.
→ The team produced distinctive A-roll that would have been difficult to cast and record conventionally.
Common mistakes
Starting visuals before the message
An impressive actor and setting cannot rescue an unclear script or weak spoken delivery.
Using the first actor generated
Skipping the audition stage removes one of the workflow's main controls over credibility and brand fit.
Ignoring facial reference quality
A reference image that hides details such as teeth forces the model to invent those details.
Is it for you?
Best for
It is best for marketers and founders producing ads, explainers, product demos, landing-page videos, and vertical social content.
Not ideal for
It is not ideal for cinematic productions, animation-led projects, or content whose value depends on documenting a real person or event.
From the transcript
“You can see you can start off by basically uploading an audio file or generating one.”
“After the audio is uploaded, you can select actors. You can go through this like audition process.”
“You can like adjust like the jump cuts and stuff like that where you want them to be in your video so you can move…”
