The Billing ClockThe two clocks on a MiniMax H3 Max generation — the one you wait on and the one you are billed for — and the arithmetic between them.

The free clip is granted once, not daily, and that changes how you spend it

Free tiers on video models come in two shapes, and the difference decides your whole evaluation strategy. One kind refills — a few seconds a day, a handful of credits a week — and rewards patience. The other is a one-time grant, and rewards planning.

MiniMax H3 Max is the second kind. One clip, granted once, when the account is made. Not daily, not monthly, not per calendar reset. Lifetime.

What the single clip actually gets you

Property Value
Quantity 1 clip, total
When granted at account creation
Length 5 s
Resolution 480P
Ratio 16:9
Audio included, generated in the same pass
Watermark none
Payment card not required
Commercial use paid plans only

Two of those rows are unusual enough to name. No watermark on a free output is rare — the standard free-tier deal is a burned-in logo, which makes the result useless for anything except deciding whether to pay. And the clip runs on the flagship post-train, not a cheaper stand-in wheeled out for free users, so what you see is what the paid plans produce.

The row that catches people is the last one: commercial use starts at the paid plans. The free clip is an evaluation artefact, not a free asset.

Spend it on your hardest prompt

Because the grant does not refill, the usual approach — burn the first one on "a cat, cinematic" to see if the thing works — wastes the only sample you get.

A single 5-second 480P clip with audio is enough to answer exactly one question well. Make it the question that would actually stop you buying:

Write that prompt somewhere else first, read it twice, then create the account. The account creation and the generation are the same decision here, which is not true on a refilling tier.

The 7-day window is the real second chance

If one clip is not enough — and for a real evaluation it usually is not — the safety net is not another free grant. It is the refund: 7 days, while the credits are untouched.

Read that condition literally, because it is the whole mechanism. Untouched. The window is not a trial you can spend and then walk back; it is a cooling-off period on an unused balance. So the sequence that works is: decide the plan, buy it, and then either run your tests inside the week or ask for the money back before you spend a credit. The sequence that does not work is buying, spending half, and then changing your mind.

And a failure is not a spend

One thing that makes the paid week less nervous than it sounds: a failed run never costs credits, and there is no per-generation fee sitting on top of the per-second rate. A request rejected for being 4 seconds long, or for an image outside the accepted dimensions, costs nothing at all — the meter never starts.

That is why the validation rules are worth reading before your evaluation week rather than during it. Errors are free; the generations you get wrong because you guessed at a limit are not.
