AI video editing is the use of generative AI models — specifically in-painting and segment edit models — to clean up, restyle, or extend existing video clips without re-shooting the original footage. Instead of doing frame-by-frame keyframing inside a traditional non-linear editor, you mark a region (a logo, a face, a 2-second gap) and the model fills, replaces, or stretches it in a single pass. AI Pin Maker's video edit tool runs this entirely in the browser and is built around fixing or extending short social clips (TikTok, Reels, Shorts) where one bad second usually meant a full re-shoot. Pricing is credit-based: the cost depends on the model and clip length and is shown before you generate. The underlying technique mirrors the inpainting research surveyed in the Stanford AI Index 2024 report .
