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

Tests of MiniMax H3 on Atlas Cloud found that its 768P and 2K options differ not only in resolution but, for text-to-video prompts, can produce substantially different generations because 2K uses an in-context regeneration process rather than a conventional upscale. In measured four-second clips, 768P delivered 1344×768 at $0.10 per second and 2K delivered 2560×1440 at $0.14 per second, with 2K taking longer to complete while providing higher bitrate and better recovery of fine details such as small product text. Repeating a text-only prompt at the two tiers changed composition, lighting, set dressing, and object placement, making a low-resolution text-to-video draft an unreliable preview of a 2K final. However, using image-to-video with a fixed first frame kept framing and scene elements consistent across tiers, allowing 768P to serve as a cheaper motion and pacing draft while 2K improves texture and readability. A separate upscaler can preserve the exact 768P performance at lower cost, but it cannot restore information absent from the original footage, so native 2K regeneration is preferable when fine text or surface detail matters. The analysis concludes that 768P is publicly available rather than gated, offers meaningful but limited batch savings, and is most useful when paired with a locked first frame or when the final clip will be upscaled rather than regenerated.
