Credit rollover: unused plan credits carried forward
A credit rollover lets plan credits left unused at the end of a billing cycle carry into the next one, usually for a limited time or only on some plans. From 5 source pages, read 2026-09-25 to 2026-10-25; no maker pays to be listed.
HeyGen rolls unused credits over for one more month on monthly plans. Runway rolls up to a month over on its Max plan only, and Krea on its Business and Enterprise plans.
Most pages on the sheet say the opposite. Higgsfield's unused subscription credits expire at the end of each month, and Pika's plan credits refresh each billing period.
A rollover changes how a heavy month is paid for: credits saved in a quiet month can be spent later instead of lost.
Where a page limits rollover to one more month, the saving is short; a season planned around it has to spend within two cycles.

2What a series pipeline carries
Limits aside, the series work behind “Credit rollover” is described in SceneMixer's guides like this:
The spoken lines and the end card follow your interface language across fifteen dialogue languages, with the cast and setting adapted to that market. The end card falls back to a language it can typeset when a script needs shaping or right-to-left layout.

About 300,000 characters of English — roughly 50,000 words — in one project. Past that, split by act or volume and run them as separate projects; the cast can be carried across.
