Kling O1 on AI Compare Hub

Kling O1 by KwaiVGI performs context-aware video editing using natural language — swap subjects, change backgrounds, restyle scenes, or insert specific elements from reference images while preserving the original clip's timing and motion. Output duration matches the input video (3–10 seconds). Resolution spans 720p through 4K, with optional element-reference inputs for precise visual control.

What you can create

• Subject and outfit swaps

  Replace the person, outfit, or product in an existing clip with a description ("change the jacket to red leather") or with a reference image of the new element. The motion, timing, and camera move from the original video are preserved exactly.

• Background and environment changes

  Restage a scene by editing only the background — move a presenter from a kitchen to a studio, swap a daytime exterior for a night-time one, or replace a green-screen background with a fully-realized environment, all without re-shooting.

• Element insertion with reference images

  Provide reference images for specific objects — props, logos, characters, or styled assets — and Kling O1 inserts them naturally into the scene. The element references trigger a higher pricing tier but give you precise visual control.

• Style and look transfers

  Restyle an entire clip with a natural-language description — "make this look like a 90s film," "give it an animated/illustrated look," "convert to black-and-white noir." The original motion, framing, and timing are kept; only the visual treatment changes.

Why creators choose Kling O1

• Context-aware, not destructive

  Most video editing tools rely on masks and frame-by-frame work. Kling O1 understands the scene, applies the requested change in context, and preserves the parts you didn't ask to change — keeping motion, lighting, and continuity intact.

• Two resolution tiers and two cost paths

  Standard (720p) at 42 cr/sec, Pro (1080p) at 50 cr/sec for prompt-only edits. Add element references to lock in specific visual assets — Standard+elements at 57 cr/sec, Pro+elements at 76 cr/sec. Pick the path that matches your control and budget needs.

• Output timing matches your input

  The output duration auto-matches the input clip (3–10 seconds). No re-timing, no audio drift, no resync work — the credit quote uses your reference video's actual duration so what you see is what you pay.

• Replaces post-production VFX work

  Tasks that previously required keying, tracking, and compositing — background replacement, prop swaps, outfit changes — collapse into a single natural-language prompt. Use it for rapid iteration on cuts and for quick one-off fixes.

How to generate your first edit

1. Upload your reference video. The clip you want to edit (3–10 seconds). The original timing, motion, and camera move will be preserved in the output.
2. Describe the edit in plain language. Be specific about what to change and what to keep: "Change the man's blue shirt to a red leather jacket. Keep the lighting, background, and motion exactly the same." Optionally add reference images of specific elements you want inserted (props, characters, logos).
3. Configure mode and elements. Pick Standard (720p) or Pro (1080p). If you've added element references, you'll be quoted at the higher elements tier (57 or 76 cr/sec). Generate and review.

Common questions

What is Kling O1?

Kling O1 is KwaiVGI's context-aware video editing model, available via the Replicate API. It performs natural-language edits — subject/outfit swaps, background changes, style transfers, and element insertions — while preserving the original clip's timing and motion. Output duration matches the input video (3–10 seconds).

How much does Kling O1 cost in credits?

Standard (720p): 42 cr/sec for prompt-only edits, 57 cr/sec when element references are added. Pro (1080p): 50 cr/sec for prompt-only, 76 cr/sec with element references. The credit quote uses your reference video's actual duration.

When are higher pricing tiers used?

When you provide element references (the elements array — reference images of specific props, characters, or assets you want inserted), the model uses the higher "video-input + elements" pricing tier. Standard mode without elements is the cheapest path; Pro mode with elements is the most expensive.

How is the output duration determined?

Output duration matches the input video's duration (3–10 seconds). There is no separate duration parameter to set — the credit quote on the platform pulls the reference video's true length once it's uploaded.

What kinds of edits work best?

Subject swaps, outfit changes, background replacement, prop insertion, and style/look transfers are all strong use cases. Edits that preserve the original scene's structure (motion, framing, lighting) work most reliably. Highly destructive edits that change everything at once may be better handled by re-generating from scratch.

Can I keep the audio from my source video?

Yes — toggle "keep audio" to preserve the audio track from the input video in the edited output. This keeps dialogue, ambience, and music in sync with the original timing.
