Minimax H3 Tutorial: Achieving Seamless Long Videos via Tail-Frame Continuation

rcscs · reddit · 2026-08-09

A developer shared a technique for creating seamless continuous videos using the Minimax H3 model. The core method involves using the last 2 seconds of the previous video as reference input for the new generation, combined with reference images to prevent facial drift.

The author emphasizes explicitly prompting the model to match the first frame of the new shot with the last frame of the reference video. This ensures the model understands the necessary motion trajectory to continue, allowing multiple clips to be joined into a cohesive long video.
