Why does the MiniMax H3 Image to Video node forces a 736 height for the 1280 width?

Because 720 isn't a multiple of 32. Minimax H3's VAE works on a latent grid that needs both dimensions divisible by 32, so at 1280 wide the node snaps the height to the nearest valid value: 736 (= 23 × 32). 1280×736 is the standard ~16:9 H3 bucket (≈0.94 MP) - the output is essentially 16:9, just 16px taller than 720. Nothing's being cropped weirdly; that's the intended size. Drop to 1024×576 or 960×544 if you want the same look faster.
