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: a typical short edit costs about 5 credits, and new accounts receive 100 free credits to test the workflow. The underlying technique mirrors the inpainting research surveyed in the Stanford AI Index 2024 report. Start with a free clip below.
