Video-to-video with intent
Give O3 a clip and a prompt. It restyles the whole sequence — lighting, palette, character look — while keeping the underlying motion intact.

Features
Why Kling O3
Object-level editing
Swap a jacket, change the background, replace a prop. O3 isolates regions inside motion so your edit doesn't leak into the rest of the frame.
Style transfer at clip length
Apply a reference look — film stock, illustration style, painterly pass — to an entire clip in one pass instead of frame-by-frame.
Kling's motion realism, on edits
O3 inherits Kling's physics and character handling, so edits stay grounded. Clothes still fold right, hair still swings with the body.
Up to 1080p at 24 fps on edits
Edited output retains the resolution and frame rate of the source clip, up to 1080p at 24 fps. No quality loss from the restyle pass — the final export matches what you'd get from a fresh Kling 3.0 generation.
Up to 15-second edit window
Apply style transfers, wardrobe swaps, and background replacements to clips up to 15 seconds in a single pass. Longer sequences can be handled shot-by-shot in Flow.
Character identity preservation
Face and body proportions survive even aggressive style changes. Restyle a clip from live-action to anime and the character remains recognizable — critical for brand mascots and recurring talent.

Who it's for
Use cases
Post-production wardrobe and prop fixes
Change an outfit, swap a product, or replace a prop in existing footage without a reshoot. O3's object-level isolation keeps the surrounding motion untouched — a VFX fix that used to take hours, done in minutes.
Style exploration for creative pitches
Take a single live-action clip and generate it in 5 different visual styles — anime, oil painting, noir, cyberpunk, film grain. Present options to a client without shooting or illustrating each from scratch.
Brand video restyling
Restyle existing campaign footage to match a new season's color palette or visual identity without re-editing the timeline. O3 applies the change across the entire clip in one pass, keeping motion and timing intact.
Social content remixing
Turn a single behind-the-scenes clip into multiple social assets — different backgrounds, different moods, different aesthetics — all from one source video. Pair with Kling 3.0 to generate the original clips, then remix with O3.

FAQ
Questions & answers
How does Kling O3 differ from Kling 3.0?
Kling 3.0 is the flagship text-to-video model — it generates video from scratch. Kling O3 is tuned for editing existing video — style transfer, object swaps, video-to-video. Use 3.0 to create, O3 to restyle.
Do I need a reference video to use Kling O3?
For the video-to-video modes, yes. O3 also supports text-only generation where the editing heuristics carry forward into the generated clip.
Can O3 handle faces and characters?
Yes. Character identity survives style transfer and restyle passes — the person in the edit still looks like the person in the source.
What's the max clip length?
Up to 15 seconds per edit in most modes. Chain edits in Flow if you need longer sequences.
Does O3 replace a video editor?
No — it replaces specific tasks that used to require VFX work: style passes, wardrobe fixes, background swaps. Your editor still cuts the film.
What resolution does Kling O3 output?
Up to 1080p at 24 fps. The restyled output matches the source clip's resolution with no quality loss from the editing pass.
How does Kling O3 compare to Sora 2 for video editing?
Sora 2 is primarily a generation model — it creates video from prompts. O3 is an edit-first model — it modifies existing video. For post-production style changes, wardrobe swaps, and background replacements, O3 is the more targeted tool.
How does Kling O3 compare to Veo 3.1?
Veo 3.1 excels at prompt-adherent generation with strong camera control. Kling O3 excels at editing existing footage. They solve different problems — use Veo 3.1 to generate new clips, O3 to restyle or fix existing ones.
Can I upload a reference image to control the restyle?
Yes. Upload a style reference image alongside your source clip and O3 will match the visual tone — color palette, lighting mood, texture style — across the entire edit.
How much does Kling O3 cost on Sunra?
Free daily credits cover several O3 edits. Beyond that, credits are deducted from your wallet or subscription allowance. Cost per edit is comparable to a Kling 3.0 generation.
