One clear subject
Choose one person or one pet. Group photos, mirrors, and objects covering the face make the subject harder to read.
Show the upper body
Use a waist-up or wider photo. Leave space around shoulders, elbows, hands, and front legs so the gesture is not cropped.
Use even light
Soft light and a simple background keep the face, clothing, arm, and hand edges visible. Avoid strong backlight and heavy filters.
Keep the original
Use a sharp original image instead of a screenshot compressed several times. Only use a photo you own or have permission to use.
The best framing, at a glance
A useful starting image shows the subject facing mostly toward the camera, with the head, shoulders, upper body, and arms visible. A slightly wider portrait is safer than a tight face crop because the bicep-heart movement needs room above and beside the shoulders. The subject does not need to be doing the pose already.
Good defaultUse one well-lit waist-up portrait with open space around both sides of the body. Save close-up selfies for a different use.
Photos to avoid
- Very dark, backlit, blurry, or heavily filtered images where the face and arm edges are unclear.
- Group shots, reflections, or a second person's arm crossing the main subject.
- Tight face-only crops, crossed arms, hands covering the face, or elbows outside the frame.
- Busy backgrounds whose colors blend into the subject's sleeves, skin, or fur.
- Images you did not take or do not have permission to use.
Person and pet photos need different expectations
For a person, choose a relaxed image where the upper torso and both arms are easy to identify. Short sleeves can make the arm outline easier to follow, but they are not required. For a pet, show one animal's face, body, and front paws clearly. A pet version should be understood as a playful interpretation of the gesture, not an exact recreation of a human hand pose.
Before you select a file
Keep an original copy on your device. If you are choosing among several images, compare them at normal phone size: can you still see the shoulders, elbows, and face without zooming? If not, choose the wider, clearer photo. Avoid sharing photos of children or anyone who has not agreed to their image being used.
Use the AI video generator with confidence
Bicep Heart supports JPG, PNG, and WebP images up to 10 MB and previews your selection before generation. Starting generation uploads the photo to Bicep Heart and fal.ai, stores the source and result privately, and uses 100 credits. Deleting a completed result is logical: it removes account access while private media awaits operational cleanup.
