H3 Max is a post-trained version of MiniMax H3 developed by fal Research and optimized for fast AI video generation. It turns a text prompt or one or two still frames into a 5–15 second video at 480P or 768P, with audiovisual output generated in the same workflow.
| Question | Answer |
|---|---|
| Model origin | Post-trained from MiniMax H3 by fal Research |
| Inputs available here | Text prompt, or a first frame with an optional last frame |
| Output duration | 5–15 seconds, in whole seconds |
| Output resolution | 480P or 768P |
| Text-to-video ratios | 21:9, 16:9, 4:3, 1:1, 3:4, and 9:16 |
| Audio | Describe dialogue, ambience, effects, and music cues in the prompt |
fal says its post-training focused on prompt adherence and visual quality while its inference work reduced latency. That makes H3 Max useful when you need to test several short creative directions instead of waiting for one long render.
Good fits include product reveals, vertical social hooks, dialogue-led clips, cinematic concepts, character motion, and first-to-last-frame transitions.
They belong to the same model family but should not be presented as identical products.
Read the full H3 Max vs MiniMax H3 comparison before choosing a workflow.
fal reported approximately three seconds of model inference for a five-second video in its launch benchmarks. That is not the same as guaranteed browser waiting time. Queueing, prompt expansion, uploads, network transfer, webhook delivery, and saving the finished file can add time.
See how fast H3 Max is for the difference between a model benchmark and end-to-end generation time.
