Where this family fits.
Preparing a bounded Kling 4 shot brief
Checking 3–30s, 720p / 1080p and auto / 16:9 / 9:16 / 1:1 / 21:9 before you run
Pacing a Kling 4 shot anywhere between 3 and 30 seconds
Deliverables that expect Kling 4 to render its own audio track
Carrying up to 10 reference images into a single Kling 4 shot
What not to assume.
Every request has to fit the Kling 4 envelope of 3–30s and 720p / 1080p; values outside it are refused before rendering.
Kling 4 always renders its own audio; the catalog lists no silent Kling 4 policy.
Motion can drift in identity, geometry, small text, logos and continuity, so Kling 4 output still needs review before publishing.
A Kling 4 request is asynchronous: a pending job is not a finished clip.
What the Kling 4 envelope allows
Kling 4 currently lists 3–30s durations, 720p / 1080p output and auto / 16:9 / 9:16 / 1:1 / 21:9 aspect ratios. Length is a free range from 3 to 30 seconds, so pacing is set by the request rather than by the model.
Choosing the workflow
Kling 4 starts from a prompt alone or from a reference image, so the first decision is which of the two carries the framing. Up to 10 reference frames are accepted per request, so more than one source frame can carry the look. Audio is rendered natively with the clip rather than added later.
How a request runs
Vizify inspects the selected policy before it sends the request, so a value outside the published envelope is refused rather than quietly adjusted. Video generation is asynchronous: a pending job is not a completed artifact, and the returned clip still needs a review pass for identity, geometry, small text and continuity before it is published.
