Credit validity: how long a credit lasts
A credit's validity is the fixed time it can be spent, counted from the day it is issued or bought, after which it is gone whether or not the cycle has ended. From 4 source pages, read 2026-09-25 to 2026-10-25; no maker pays to be listed.
Kling AI and OiiOii give monthly credits 31 days from issue, Vidu 30 days, and Frameo 180 days. Kling AI's purchased credits last two years, as do Vidu's.
Validity is a different rule from a reset. A reset empties the balance on the renewal date; a validity period runs from each credit's own start.
Frameo's 180 days are long enough to carry a plan's credits across most of a season, which few other pages on the sheet allow.
When a page gives two lifetimes, one for plan credits and one for bought credits, spend the shorter-lived ones first.

2Making the series in practice
Limits aside, the series work behind “Credit validity” is described in SceneMixer's guides like this:
A script longer than about 10,000 characters (counted as Chinese-equivalent characters) is read in two passes: first the cast, sets and props, then the episode list with a short outline per episode.
SceneMixer, Long Scripts Are Read in Two Passes: What “Preparing Episodes” Means and Why Some Episodes Open Later (read 2026-10-13)
Scene order, dialogue and beats follow the script; what the pipeline adds is coverage — which shot sizes, who is in frame, how long each shot holds.
