loop_video

Loop a performance bank

Rotate one to three owned 1–15 second video takes to a target duration, up to 30 minutes. Plain loop or ping-pong. Output is silent for dubbing. Free; uses storage. get_generation waits for the result.

Scope

generation.write — Makes, edits, imports, shares and deletes media in the account.

Behaviour

Writes: Creates or changes items in the caller's own account.
Adds or updates: Adds or updates; nothing the caller already has is deleted or overwritten.
Stays in the account: Stays inside the caller's private Kuro account: any media provider it calls acts on Kuro's account, and the result is visible to no one else.
