Minimax H3 Context Loss: Background Changes After 13s at 0.9MP

MarekNowakowski · reddit · 2026-08-16

A user discovered that Minimax H3 video generation loses context when total pixel count exceeds a limit (e.g., 13.1s at 0.9MP). Beyond this threshold, the model 'forgets' the background, shifting to a blue wall or different camera angle. Reducing resolution or duration mitigates the issue, suggesting a limited attention window based on pixels.
