RA2 CHARACTER FRAME · MINIMAX H3 + SWAP LORA · ORIGINAL AUDIO
Swap the characters. Keep the scene.
A character-swap LoRA on MiniMax H3 replaces the people in your footage with the characters from one reference image while the source video drives the camera, background, lighting and motion. Clips follow the original cuts, are joined with the untouched soundtrack, and the whole job is priced per source second before you start.
