Kling 4.0 Flash
The quick edition of Kling 4.0 — from words, from a first frame, from your reference pictures, or on a clip of yours.
Kling 4.0 Flash is the quick edition of Kling 4.0. It works four ways: from your words alone, from a picture of yours as the first frame, from reference pictures that guide a new video, and on a clip you already have, changing what your words say. When Studio offers it, you find it under Videos on Studio's home and Generation in Choose a model.

The price is never written here — prices change. It is on the model's page in Studio: on the Make button and beside each length, size or quality that changes it, before you press.
Writing for it
Say what happens, in order. From a frame, the video keeps your picture's shape.
With reference pictures, name each one where it matters — type @ and pick it.
Edit changes what you describe on a short clip of yours; add pictures to show what the change should look like.
