Kling Video O3 Pro Video Edit

Kling Video O3 Pro Video Edit is Kuaishou's most advanced video editing model, enabling natural-language-driven edits on existing video footage. Upload a video, describe the change you want — swap objects, alter scenes, shift styles — and get high-quality edited results with preserved motion and structure. Supports up to 4 reference images for precise visual guidance and optional original audio retention.

Why Choose This?

Prompt-driven editing Describe your edits in plain language — no timeline, no masks, no manual keyframing required.
Reference image support Attach up to 4 reference images to guide the target element, scene, or style in the output.
Audio preservation Keep the original soundtrack intact with the keep_original_sound option.
Element list control Lock in specific visual elements — characters, objects, or styles — to maintain consistency across the entire clip.
Scene-level understanding The model recognizes objects, backgrounds, and context within the video to apply accurate, context-aware edits.
Motion-consistent output Edits blend naturally across frames with strong temporal coherence — minimal flicker or ghosting.

Pro Tips

Use clear, specific prompts describing exactly what should change for best results.
Reference images work best when they clearly represent the target element or style.
Keep keep_original_sound enabled when audio continuity matters for your project.
Test edits on shorter clips first, then apply to longer footage once satisfied.
Ensure video URLs are publicly accessible — a preview thumbnail in the interface confirms the link works.

Notes

Both prompt and video are required fields.
Billed duration is clamped between 3 and 10 seconds regardless of actual video length.
Using element_list: First use Kling Elements to generate your element and note its name and ID. Then simply write the element name naturally in your prompt, and enter the corresponding element ID in the element_list field. No special characters or syntax required.
If using a URL, make sure it is publicly accessible.

What is the Kling Video O3 Pro Video Edit API?

Kling Video O3 Pro Video Edit is a Kuaishou model for video editing, exposed as a REST API on WaveSpeedAI.

How do I call the Kling Video O3 Pro Video Edit API?

The playground generates a ready-to-paste code sample in Python, JavaScript, or cURL for whatever inputs you've set.

The exact cost for your current input is shown live next to the Generate button before you submit, and the actual per-call charge is recorded on the prediction afterwards.

What inputs does Kling Video O3 Pro Video Edit accept?

Key inputs: `prompt`, `images`, `video`, `element_list`, `keep_original_sound`, `shot_type`.

Can I use Kling Video O3 Pro Video Edit outputs commercially?
