BicepHeartBicep heart video hands look wrong? 6 things to change before you regenerate
Six concrete photo changes that make the pose easier for an AI model to read.
1. Give each hand its own space
A hand resting against another person, a phone or a sleeve gives the model several shapes to untangle. Choose a photo where the fingers are separated from nearby objects. Start with a relaxed pose rather than an already complicated heart gesture.
2. Keep both elbows inside the photo
A face crop leaves the model to invent the arms. Back up to a waist-up image with breathing room above the shoulders and outside the elbows. Do not cut off the wrists at the frame edges.
3. Show the upper arm
A fitted short sleeve or sleeveless top makes the shoulder-to-elbow relationship easier to read. Bulky coats and folded sleeves can hide where the arm bends.
4. Use even light
Strong shadows can merge fingers into a dark background. Prefer soft daylight and a clear edge around the hands. Increasing brightness cannot restore detail that was never captured.
5. Remove competing subjects
Use one person. A second face, a mirror reflection or someone else’s hand can become part of the animation. Choose a different source image instead of blurring away a crowd.
6. Change the source before spending again
Compare the failed frame with your source. If the same hand is hidden in both, a new random take may repeat the problem. Each completed new take costs 10 credits; automatic failed-job refunds do not mean every visually imperfect completed clip is free.
