How to write lyrics and direction for an AI duet video
Add your own lyrics, performance directions, or both in the optional text box. You have up to 500 characters to shape the singing style, camera mood, and movement. Leaving the box blank gives you our standard performance.[1]
How to write your lyrics and direction
Four helpful details to include are who starts first, what each person does, how they deliver the lines, and the overall mood on camera.[2]
Who goes first
Name who sings or speaks the opening line. Setting the starting order helps create a natural back-and-forth flow across the scene.
What each person does
Describe actions across the scene, such as turning toward each other, pointing to the camera, or stepping through a small dance.
How to sing it
Choose a vocal style for the lines, such as rap, slow melody, or a soft whisper to guide the sound.
Mood on camera
Set the emotional tone for the scene, from upbeat and energetic to calm, playful, or thoughtful throughout the performance.
What to leave out
- Skip lyrics you lack rights to, and choose your own words to keep your video yours.
- Skip names of real public figures so the focus stays on your two subjects.
- Skip harmful or unsafe words to help the AI model process your scene smoothly.
- Save lengthy paragraphs for longer scenes, matching brief lines to shorter clips.
Video length and credit costs
Select 5, 10, or 15 seconds for your video. Credits are charged per second of video, and shorter text naturally suits a shorter video. The full credit cost displays clearly before you generate your scene.

Frequently asked questions
Do I have to write lyrics and direction?
Writing in the box is completely optional. If you leave it empty, your scene uses our standard performance with default movements and vocal delivery. Adding your own words is simply there whenever you wish to customize who sings first, how the characters move, or the overall mood.
Can I use lyrics from my favourite song?
We recommend writing your own words or choosing lyrics you have permission to use. Creating original lines keeps the video uniquely yours and respects songwriter rights. You can write rhymes, spoken dialogue, or a simple greeting that fits your two characters.
How closely will the video follow my words?
Your text guides the overall performance, and each video is a fresh creative take. After your video is ready, take a moment to check that the visuals and lyrics match what you had in mind. You can always adjust your wording and create another take to explore different results.
How long can my lyrics and direction text be?
You can write up to 500 characters in the text box. That provides plenty of space to outline who sings first, detail specific actions like dancing or pointing, specify a singing style, and set the camera mood for your scene.
What happens to my credits if the AI model cannot use my text?
If the AI model cannot use your added text, all credits charged for that video return to your balance automatically. Nothing else is charged, allowing you to revise your description and try again whenever you are ready.
