What a second of AI video costs, channel by channel

Where unused credits go on invideo AI

invideo AI gives this column a single sentence saying credits do not roll over to the following month. There is no plan-by-plan variation and no grace period, which makes the allowance a use-it-or-lose-it quantity. As of 2026-09-22.

What one sentence settles and what it leaves openThe pricing page states that unused credits do not roll over to the next month, and that is the whole answer. It covers every plan without distinguishing between them, and it says nothing about credits acquired outside a plan or about what an exhausted allowance does mid-month.What happens when a month ends with credits leftAnsweredThey lapseOne sentence, on the pagecarrying the plan prices,with no plan-by-planvariation.Not addressedCredits bought outsidea planOther channels treat thesedifferently; this pagedoes not distinguish them.Not addressedHitting the capmid-monthStopping, queueing andcharging on are threedifferent outcomes for adelivery date.One published sentence, two unpublished consequences

Inclusion rule. Channels whose own priced pages say something about credits left unspent, including the ones that raise the question and leave it unanswered. A channel that never meters in credits has nothing to answer and is not listed. Order. Alphabetical by channel name.

2A one-sentence answer is worth more than it looks

This column is mostly filled with hedges, cycles and exceptions. A flat statement that the allowance does not survive the month is the easiest version of this fact to plan against: the effective cost of a month is the plan price, whatever fraction of the allowance was used.

That also makes the seller's incentive legible. An allowance that expires rewards steady monthly output and punishes bursts, and a production working in bursts is paying for months it barely used. Nothing else needs to be worked out.

3What the sentence does not cover

It says nothing about credits acquired outside a plan, which on other channels is the half that behaves differently. If no such purchase exists here, the omission is correct; if one does, the answer for it is missing from the page that prices it.

It also says nothing about what an exhausted allowance does mid-month. Stopping, queueing and charging on are three very different outcomes for a delivery date, and the pricing page treats the boundary as a quantity rather than an event.

4Why this entry sits outside the ledger

invideo AI is recorded here as a channel without a computable rate, because the credits it meters in are quoted per video rather than per second and no credit price appears. This column is the part of its pricing that is fully published, which is why it has an entry at all.

Read together, the two facts describe a monthly product rather than a metered one. For a buyer that is a legitimate shape; it just cannot be compared against a figure in dollars per second without inventing the missing half.
