MiniMax H3
MiniMax
Follows a long, specific brief more literally than the rest of the video lineup. MiniMax H3 — strong prompt adherence and reference support. 4–15 seconds; uooki drives it from a first frame only.
Using MiniMax H3 in uooki
uooki has no model picker. You name the model in the conversation and the agent routes to it — “make the clip with MiniMax H3” is the whole interface. Common spellings and older ids resolve to the same model, so you do not have to match our internal naming.
Leave the model out and the agent picks one for you based on what you asked for. Naming it is for when you have a reason to — this page is about those reasons.
What it is good at
- A shot where the brief names several things that all have to happen — camera move, subject action, lighting
- Clips built from a reference image you want honoured rather than loosely interpreted
- Anything between 4 and 15 seconds; it is the longest single clip in the catalog
Where it is not the right pick
uooki drives it from a first frame only — the video tool has no last-frame input, so no controlled A-to-B transition, even though the model itself accepts one. Four seconds is a hard floor: ask for less and you still get four. It runs on a single provider, so there is no failover.
When to reach for something else
- PixVerse V6
You want the cheapest clip with sound, and the brief is simple.
- Veo 3.1
You need the strongest overall motion quality and can pay for it.
