In what order credits are spent

Three things can pay for an operation, and they are always tried in the same order: your plan’s monthly credits, then extra credits, then a pay as you go balance. Nothing reaches the balance while credits of either kind remain.

​

One operation, one source

An operation is funded from a single source. If your plan credits cannot cover the whole amount, the charge does not split: it moves on to extra credits and is taken there in full. So the last few plan credits of a month sit untouched while a larger operation is paid for out of the next source along.

What each operation weighs

Video mockups are weighted by the clip you ask for rather than by a flat figure.

​

Plan credits

Plan credits are the monthly allowance that comes with your plan. At each renewal the allowance is set back to the plan’s figure and the usage counter returns to zero, so unused plan credits do not carry into the next month. On a plan change the allowance is recalculated for the plan you moved to and the usage you have already recorded that period stays as it is.

​

Extra credits

Extra credits are bought in packs on top of a plan, and they behave differently on purpose. They do not reset at renewal, they do not expire, and they stay on the account after a plan ends. A pack is a count of credits rather than a sum of money, so its size does not change when you move between plans: one credit buys the same work on every plan. Because they sit second in the order, a pack is only touched once the month’s plan credits are gone. That is what makes it useful as a reserve for a heavy month rather than something you have to plan around.

​

The balance

A pay as you go balance is last. It is money rather than credits, so it is spent per operation at the price for your account, and it is what keeps a queue running when both credit pools are empty.

​

Refunds

A failed operation is returned to the source it came from: plan credits to plan credits, extra credits to extra credits, balance to balance. A render that never produced an image is never charged for.

Reading the numbers

The Billing page shows all three: the month’s remaining plan credits, the extra credit count, and the balance with a ledger of what was added and what it went on. Retrieve the current account reports the plan’s remaining credits and the balance to your own code.
