New in Sondo AI: Duo Music Video Is Here!
Sondo AI introduces Supporting Character Upload for duo music videos. Add a second character reference for clearer identities, better consistency, and more personalized two-character stories
Creating a music video with two people opens up more ways to tell a story. It can be about a couple, two friends, family members, creative partners, or simply two characters sharing the same visual narrative.
But when a second person appears across multiple scenes, keeping that character recognizable can be challenging.
That is why Sondo AI is introducing Supporting Character Upload, a new feature designed to give creators more control over the second important character in a music video.
You can now upload a separate reference image for a supporting character alongside your main character, helping AI better understand who should appear in the story and how the two characters should remain visually distinct.
What’s New: Supporting Character Upload
With the new Supporting Character Upload feature, you can provide a dedicated reference image for the second important person in your video.
Your creative setup can now include:
Song + Main Character + Supporting Character + Creative Idea
Instead of relying only on text to describe the second character’s appearance, you can directly provide a visual reference.
If you want to create a music video about a couple, two friends, or two people sharing a story, you can upload a separate image for each character and then use the prompt to describe where they are, what they do, and how they interact.
1. Better Control Over the Second Character
Supporting Character Upload gives the second person in your music video a clearer visual reference from the start. Instead of relying mainly on text to describe their appearance, you can upload a dedicated image that helps Sondo AI better understand who that character should be.
This is especially useful when the supporting character appears across multiple scenes. Their setting, clothing, or position in the frame may change, but the reference image provides a consistent visual anchor for details such as facial features, hairstyle, age, and overall appearance.
By defining both the main character and supporting character separately, you also give the model clearer information about which person should appear in each part of the story. This helps make two-character scenes easier to control and keeps the second person from feeling like a generic or loosely defined background character.
2. Build Clearer Two-Character Stories
A two-character music video is not only about placing two people in the same frame. The relationship between them often shapes the story itself.
With separate references for the main and supporting characters, you can define both people visually and then add your prompt to describe how they connect. This makes it easier to build a clear narrative around their roles, actions, and shared moments.
For example, you could create:
A couple spending a quiet weekend together, from morning coffee to a sunset walk.
Two friends taking a road trip, stopping at a diner and exploring a new city.
Two family members revisiting familiar places and shared memories.
A main character moving through the story while an important second character appears at key emotional moments.
The character references establish who is in the story, while your prompt establishes what happens between them. Together, they give the video a stronger narrative structure and make interactions between the two characters feel more intentional.
❌
Two people spend the day together.
✅
“The main character and supporting character spend a relaxed summer afternoon together, stopping at a café, walking through a quiet neighborhood, and watching the sunset from a rooftop.”
3. More Ways to Create Personalized Music Videos
Supporting Character Upload also expands the types of personalized stories you can create with Sondo AI.
Couple Stories
Turn a favorite song into a story about two people—from a first date and weekend getaway to quiet everyday moments at home. Let the main and supporting characters share small interactions that make the relationship feel personal and connected.
Friendship Videos
Follow two friends through a spontaneous day out: grabbing late-night snacks, exploring city streets, taking photos, or watching the sunset together. Mix individual moments with shared scenes to capture the energy of a real friendship.
Revenge Stories
Build a more dramatic two-character narrative around betrayal, rivalry, or a comeback. One character might walk away after being underestimated, rebuild their confidence, and return stronger while the supporting character becomes part of the conflict that drives the story forward.
Adventure Duos
Send two characters into the same adventure. They might take a road trip through the desert, explore an unfamiliar city, hike toward a remote viewpoint, or step into a fantasy-inspired world together. Alternate between solo discoveries and shared moments to make the journey feel bigger and more cinematic.
Supporting Character Upload makes it easier to explore a wider range of storylines instead of limiting two-character videos to one type of relationship. Your characters can fall in love, grow apart, compete, reconcile, escape together, or take on an entirely new world—the relationship between them can become part of the story itself.
By defining both characters with reference images, you have more freedom to experiment with different moods, conflicts, settings, and narrative structures. From warm everyday stories to dramatic revenge plots and cinematic adventures, one song can become the starting point for many different two-character stories.
Tips for Better Supporting Character Results
Use Clear Reference Images
Choose images where each face is clearly visible.
Front-facing or slight three-quarter views generally work well. Good lighting and minimal obstruction can also provide a clearer visual reference.
Avoid images where the face is heavily covered by hair, hands, sunglasses, or other objects.
Give Each Character a Clear Role
Describe what each person should do in the story.
For example:
“The main character prepares dinner while the supporting character sits nearby and helps set the table.”
Clear actions are more useful than broad instructions such as “they spend time together.”
Keep Character Labels Consistent
Use the same labels throughout your prompt.
For example:
Main Character
Supporting Character
Avoid changing between several different names for the same person.
Mix Individual and Shared Shots
Both characters do not need to appear in every scene. Alternating between solo shots and two-person scenes can create a more natural rhythm and give each character a clearer presence.
Describe Important Interactions
If the two characters need to interact, explain exactly what happens.
For example:
“They sit across from each other at a small café table.”
“They walk side by side along the beach.”
“They sit together by the window and look through old photos.”
Specific actions give the model a clearer visual direction.
Keep the Story Focused
Two characters already introduce more visual complexity. A focused story with a few connected locations and simple actions is usually easier to follow than one filled with many characters, locations, and unrelated events.
Create Stories Around Two Characters
Some music video ideas are naturally built around more than one person. With Supporting Character Upload, Sondo AI gives you a more direct way to define that second person.
Upload your song, add your main character, provide a reference image for your supporting character, and describe the story you want to create. With clearer character references and more control over each role, you can build Duo Music Videos that feel more personal, connected, and intentional.
