What a second of AI video costs, channel by channel

What a quiet month costs on a monthly allowance

Where a monthly allowance expires, the effective rate is the advertised one divided by the share of the quota actually used. A production using half its allowance is paying twice the headline figure, and no pricing page shows that number. As of 2026-09-12.

The same plan, three answers, three effective ratesAn allowance that lapses makes the advertised rate a floor: a buyer using half the quota pays twice the headline figure. One month of grace smooths a single slow month and caps a buyer at two allowances at once. A quota pooling to a renewal date removes the problem entirely.What does the page say happens to unspent quotaIt lapsesDivide by utilisationHalf the quota used meanstwice the advertised rate,and no page shows thatnumber.One month of graceTwo allowances,maximumSmooths one slow month.Two quiet months in a rowand the first is goneanyway.It pools to renewalThe figure is thefigureBursty output stops beingpenalised, which is worthmore than most price cuts.Expiry rewards even output and punishes bursts

Inclusion rule. The answers a priced page can give about quota left unspent, with the arithmetic each one implies. An answer no page in this register gives is not listed. Order. From the answer that costs a buyer most to the one that costs least.

1Utilisation is the figure a buyer supplies

Every allowance-based rate in a comparison is really a rate divided by a utilisation number, and the only person who can supply that number is the buyer. A studio generating steadily every week and one working in bursts around delivery dates pay different effective rates on the same published plan.

That is knowable in advance and almost never worked out, because it needs a production calendar rather than a price list. An hour with a calendar is worth more than a week comparing headline figures.

2Expiry rewards steady output and punishes bursts

A quota that lapses monthly is a bet that output will be even. Serial production is rarely even: a script pass, then a burst of character sheets, then a quiet fortnight of review, then every segment of two episodes at once.

Against that shape, a plan whose quota pools to a renewal date can be worth more than a visibly cheaper one that resets. The difference is a factor rather than a percentage, and it is invisible in every comparison built from advertised rates.

3What to do when the page is silent

Assume the worst case and compare on that. It costs nothing if the assumption is wrong and saves a month of wasted quota if it is right. Where the seller has raised the question in its own material and not answered it, the policy exists and the sentence is missing, which makes the pessimistic reading more reasonable rather than less.

The alternative habit, taking the advertised figure and hoping, produces a budget that is correct only for a production that consumes everything it buys. Very few do.

Written to explain, not to record. No sentence here is attributed to a seller, and none of it should be quoted as a fact about one. The sourced material is on the ledger. Related: Assumed averages, Buying machine time.

4What the seconds buy

Price aside, what goes into the seconds behind “A quiet month” is described in SceneMixer's guides:

SceneMixer turns a novel into a watchable short-drama series in one pipeline: upload the novel (Chinese or English) → AI extracts characters, scenes, and an episode-by-episode structure → generates consistent character and scene art → writes storyboard scripts → renders video segment by segment (16:9 by default, 9:16 in one setting) → composites full episodes.

Paste a scene or a short script and SceneMixer gives you a storyboard — numbered shots with framing and seconds — and then a moving version of each segment, which you can join into a rough cut of the scene.
