Biceps Heart is a web based AI video generator for creating a short video from a still photo. It animates the person in the image into the bicep heart pose, in which one arm is flexed and the other hand curves over the bicep to form a heart shape. The service produces an approximately seven second vertical video that can be previewed and downloaded as an MP4. To use it, a person signs in with Google, selects a credit pack, uploads a photo, chooses a style and selects 720p or 1080p quality before generating the video. Generation costs one credit at 720p or two credits at 1080p. The site recommends a clear photo of one person visible from the waist up, with both arms and face in frame, even lighting and a simple background. Short sleeves or sleeveless clothing can make the upper arms easier to see. HEIC images must first be saved or exported as JPG files. The website also explains the bicep heart trend, provides examples made with fictional people and displays creator videos embedded from TikTok. Users should only upload photos they have permission to use. Uploaded photos are processed to create a video, and the site states that private photos and videos are scheduled for deletion after seven days.
