MiniMax H3 2K vs 768P: I Ran the Same Prompt Twice and Got Two Different Films

MiniMax H3’s 768P and 2K video options differ not only in resolution but, for text-to-video prompts, can produce substantially different generations because the 2K mode regenerates the scene using the original context rather than simply upscaling a 768P output. Tests on Atlas Cloud found that 768P delivered 1344×768 video at $0.10 per second and 2K delivered 2560×1440 at $0.14 per second, with 768P generally returning faster but offering a 29% per-second saving rather than a dramatic price reduction. Identical text prompts produced changes in composition, lighting, set dressing, and object placement between tiers, making an unanchored 768P draft an unreliable preview of a 2K final. However, supplying a generated still as the first frame through image-to-video kept framing, setting, and label placement consistent while allowing 2K to improve fine texture and small text. Conventional upscaling preserved the exact 768P take at lower cost and speedier turnaround but could not restore missing fine detail, so the recommended choice depends on whether preserving a specific performance or recovering high-resolution details is more important.
