MiniMax H3 image-to-video auto-stretches output at 1344x768 but works fine at 1056x608

A Reddit user reports odd behavior in a MiniMax H3 image-to-video workflow: 1056x608 (0.6MP) runs cleanly, but at 1344x768 (1.0MP) the output video automatically stretches upward, with the black borders at top and bottom being cropped away. Both resolutions are multiples of 32, so the model's dimension requirement is met. The user suspects the 1.0 megapixel setting or the frame-count formula at length=124, and links the full Civitai workflow. No resolution yet.
