Most bad bicep heart AI videos come from the photo: one arm cropped, long sleeves, a busy background or a hand already hidden. Fix the photo first, because a rerun with the same picture often repeats the same mistake. Renders that fail or are blocked here return their credits automatically; a finished clip you dislike is a new paid try.
One sharp photo of one adult is all the generator takes. You do not have to be flexing in it; the pose is added for you. Accepted: JPG, PNG, WebP · max 10 MB · min 300 × 300 px.

This is the most common miss for every video model. The usual causes are a hand that is half out of frame, fingers already touching your body in the photo, or a sleeve covering the upper arm where the hand needs to land.
Use a photo where both hands are fully visible and away from your body, with short sleeves or bare arms and space around the elbow that will rise.
Faces drift most when the face is small, turned away or in shadow. Pick a photo taken closer, facing the camera in even light, without sunglasses or a hand near the face. The generator invents the motion, so some frames always differ a little from the photo.
Models sometimes exaggerate the flex. A photo where the arm is clearly visible, rather than hidden by a baggy top, gives the model the real shape to follow. If a clip changes your body in a way you do not like, do not post it; try a clearer photo instead.
A render that fails, or that the safety screen blocks, returns its credits to your balance automatically; you do not need to ask. Long waits usually mean a busy queue. The job keeps running if you close the tab, and the clip appears in My Creations when it is done.
Photos of minors, of more than one person, of public figures or with nudity are not allowed, and the safety screen may stop them before anything is charged.

Change something first. A new render is a new paid attempt and the same input often gives the same kind of mistake. Switch to a sharper waist-up shot, short sleeves and both hands in view, then render again.
