The scene and movement
The setting is a steady waist-up portrait showing both arms. The person smiles, flexes one arm and curves the other hand against the bicep to form a small heart before holding the pose. Your generation uses the prepared opening 7 seconds, so later moments in a full-length example may fall outside your result.
A readable heart shape matters more than exaggerated muscle size. The reference is a short fixed gesture, suitable for a greeting or playful gym update.
The role your photo replaces
For this template, your photo defines the single person performing the arm-and-hand heart. Use the editor preview to locate that role before uploading. The photo guides appearance, hair or fur, body proportions, and visible clothing; it does not record a new voice.
Use one photo per labeled role. Subjects without an upload slot keep their reference appearance.
Prepare a useful appearance reference
Choose one waist-up photo with both shoulders and arms visible. Leave space beside the head for the raised elbow.
Keep one subject clearly separated from the background. For Bicep Heart, pay particular attention to fingers against the bicep, elbow position, facial identity and the final heart silhouette. Include the body and outfit details that will be visible in those moments; avoid a collage or a group photo.
What follows the prepared reference
The camera path, scene order, supporting cast and props come from the prepared clip. The instructions preserve a steady waist-up portrait showing both arms and the movement described above. Replacing the appearance does not add separate controls for a new location, a different prop or another choreography.
Review these moments in the result
Play the entire result at normal speed, then pause around fingers against the bicep, elbow position, facial identity and the final heart silhouette. Check the same identity before and after a turn or overlap. A strong first frame does not guarantee that every later frame is consistent.
Length, credits and sound
The prepared generation is 7 seconds and costs 2 credits. The collected full reference is about 7 seconds. Previews can be longer and are free to play. The quote on Generate applies to the prepared clip, not to every second in the example gallery. Short-template estimates on this guide use 720p; choose 480p in the studio to see its lower quote. Long-template estimates use fixed 480p pricing.
The original audio is kept separately and merged into the finished video. Preview with the sound controls before creating.
