Prompt to Video: Create Talking Videos from Text Prompts

Overview

Go from 0 to video with just a prompt — enabling anyone to go from idea to edited talking video, featuring actors that don’t exist. With this first-of-its-kind tool, it’s never been easier to turn text into professional-quality videos or ads. Prompt to Video is powered by Mirage, our groundbreaking video generation model.

What edits are applied to the video?

All elements of professional video storytelling are seamlessly combined into one cohesive experience:

A-Roll: A Mirage-generated actor addresses the camera directly, delivering your message with natural expression and movement.
B-Roll: Contextual images and videos are generated and thoughtfully incorporated to enhance your video and message.
Professional editing: Our model will then analyze the content and apply choice transitions, sound effects, music, zooms, cuts, and other edits.

The result is a fully produced and fully AI-generated talking video that’s engaging and polished — all from a single prompt.

How It Works

iOS
Desktop (Web)

On the home screen, you can start by writing your video idea in the prompt field or importing a voiceover track.
Choose your language from the dropdown
Browse and select your actor or generate a new AI Twin
Choose an Edit style and custom color
Select media to be included in your video (optional)
Preview and select the voice for your actor (you can also generate a voice clone based on your own voice)
Tap Generate Video

After the video is done generating, you can open the video in the Captions editor to make adjustments to shot styles and edit your video before exporting.

Captions lets you turn a script or voice clip into a fully custom, actor-driven video. Here’s how to get started:

1. Add Your Script or Audio

You can either type your script or upload/record your own audio.

Write a script: Enter up to 30 seconds (or 1,000 characters) into the text field. Choose a language and one of our built-in voice options.
Upload audio: For more control, upload your own voice recording (audio or video file). Mirage will automatically extract and use the audio.
Record audio: Click Record to capture audio directly in Captions. Review and retake as needed before applying it to your project.

Your audio quality will affect the video. Try to record in a quiet space with a tone that matches the scene you’re going for.

2. Pick a Voice (if needed)

If you didn’t upload/record your own audio, choose a voice from our partners (like ElevenLabs or Google).
You can also trim the start or end of the audio to remove silences.

Make sure the voice matches your actor description. For example, don’t pair a deep male voice with a teen female actor unless you’re going for something unique.

3. Choose or Create an Actor

You have three options here:

Choose an already generated actor from the actors library

You can use the actors library to choose an already generated actor provided by Mirage.

Upload a reference image

Create an “AI Twin” of yourself or someone else (with permission).

5. Export Your Video

Once you’re happy with the result:

Download the video to share anywhere
Export as a .zip if you want all files, including audio
Reshoot all clips if you want to try a fresh version
Delete if it’s not something you want to keep
