H3 Video Model Review: Great Motion Control but Slow, 15s Takes 800s on A100

A Reddit user shared their hands-on experience with the Min Max H3 video generation model. Overall, the model excels in motion control (such as prompt-guided movements and full-body interactions) with face consistency rated 8/10 and very low censorship.
Regarding performance, generating a 15-second vertical video at 0.9 MP resolution takes about 800 seconds on an A100 80G GPU. The user noted that using the official prompt structure yields better results and is currently looking forward to the Turbo LoRA to boost generation efficiency.
