Start with the finished vertical video
Download the 7-second 720 × 1280 MP4 from your order and preview it before importing it into TikTok, Instagram Reels or another editor. Keep the face, both arms and the heart shape visible when choosing a crop. Adding captions or interface overlays directly over the hands can make the short gesture harder to recognize.
Choose sound inside the destination app
Use music available to your account for the intended use, or a track you separately have permission to use. Platform libraries and permitted uses can differ, including for commercial posts. If an original bicep heart trend song is unavailable, choose another suitable sound rather than extracting someone else's audio and assuming it is reusable. This page does not identify a single verified original song.
Fit the edit to a seven-second gesture
Watch when the arm movement begins and when the heart is held, then trim your chosen sound to that section. Keep enough of the held pose for a viewer to understand the result. Avoid claiming that this generator synchronizes lip movements or choreography to an uploaded song: custom music input and beat matching are not features of this service.
Label realistic AI content appropriately
The result is an AI animation of a photo, not footage proving that the person performed the movement. Follow the destination platform's current rules for disclosing realistic AI-generated content. TikTok's official guidance is linked below. Use a consenting adult's photo and do not frame an edited clip as someone else's endorsement or an authentic event.
