trim_video

Trim a video

Save one stretch of an owned video as a new clip, using a keyframe copy by default. Set accurate true to re-encode an exact window for seamless adjacent cuts. Specify the start time and duration in seconds. Video only; a sound is trim_audio. Costs no credits; uses account 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.

Credits

What the tool's description says about credits, verbatim.

Costs no credits; uses account storage. get_generation waits for the result.
