A short routine in one continuous take
One adult portrait guides the performer. Leave room for both arms; the final hand-to-arm contact is the detail to review.
Before you start
A fixed-camera routine
Follow the smile, crossed arm, flex and final heart without scene changes.
A short clip with sound
The finished video includes the matching reference audio.
One flex, one hand, one complete heart
The small movement matters: the heart comes from the shape of your arm and hand, followed by a short hold.
Keep the whole gesture visible
Leave room beside the head and across the chest. Cropped elbows or hidden hands give the model less guidance for the heart.
Close the heart with the free hand
The other hand meets the inside of the bent arm. It is a physical outline made by the pose, rather than a graphic placed over the body.
Hold the ending and review the hands
The last moment lets the heart register. Watch the wrists, fingertips and face through the whole clip; precise contact can vary between generations.

FAQ
Questions before generating
Do I need muscular arms?
No. The preset requests your natural build. Short sleeves and enough space around the arms matter more than muscle size.
Can I use a close-up selfie?
A face-only crop is a weak reference because it hides the arms. Use at least a head-to-waist photo with both arms visible.
Can I upload a pet or two people?
This version is for one adult. Pet anatomy and two performers need different motion handling and are not offered here.
Does it use the reference sound?
The model renders silent footage, then the matching reference audio is added to the result. No new spoken message or custom song is generated.
Why might the heart or fingers look wrong?
Hands must touch a specific part of the arm. Occlusion and tight crops can cause extra fingers or an unclear outline; inspect the full video before sharing.
Does changing my notes cost credits again?
Yes. Each new submission is a separate generation with its own displayed quote. Downloading an existing result does not create a new generation.
