Framelock

FrameLock lets AI filmmakers change a video’s environment without rerolling an approved character performance. It validates and hashes the original 1280×720, 121-frame sequence, uses fal VEED to extract a frame-by-frame foreground mask, Nano Banana Pro to create replacement environment plates and Kling O3 to animate the selected world. FrameLock then composites the original character locally and restores every pixel inside its protected core from the canonical source frames. A separate verifier reopens the completed sequence and approves it only if all 121 protected-core hashes match with zero changed RGB samples—before MP4 encoding.
