Explore Kling O3 video editing with a source clip, image references and subject elements. Learn how to brief and review a focused scene change.
This is a model feature guide. This model is not listed in Longtake's current catalog; the workspace offers other models.
The O3 editing endpoint takes a source video and an edit instruction. Treat it as a revision workflow: replace a setting, change a subject or restyle a shot instead of describing an unrelated film from scratch.
Image references and elements can help specify the replacement subject or visual treatment. For a room redesign, provide the target palette and describe which surfaces should change without introducing a second camera move.
Review the edit against the source at the opening, middle and end. Check object boundaries, reflections and the subject's silhouette, not just the most attractive frame. Keep the original clip until the revision passes your review.

Editing uses an existing video as the starting point. Generation creates a new clip from a prompt and the references supported by its endpoint.
Do not assume pixel-identical preservation. Inspect unintended changes to the background, movement, face and soundtrack before accepting the edited clip.
