What is Kling 3.0 Omni Edit?

Kling 3.0 Omni Edit is the video-to-video editing route under Kling 3.0 Omni. Pass a source video (up to 10 minutes from the playground) and a prompt describing the edit, and the model returns a new clip of the same length. The reference bundle is up to 4 across image_urls and elements combined (shared cap of 4). Two video modes drive the result: Reference uses the source as a style or motion guide while the prompt steers the change; Transform reshapes the source more aggressively. keep_audio preserves the original soundtrack, which is useful when audio continuity matters. Output renders at Standard (720p) or Pro (1080p), in 16:9, 9:16, or 1:1.

Key features of Kling 3.0 Omni Edit

Five features cover what teams build with Omni Edit.

Edit a source video with a single prompt

Pass video_url and a prompt describing the edit. Output length follows input length, so the timeline stays put while the visual changes.

Reference and Transform video modes

Reference treats the source as a style or motion guide for the prompted change. Transform reshapes the source itself with a heavier restyle or retime. Pick the right one for how aggressive the edit needs to be.

Image and video elements in the reference bundle

The elements array supports both image and video element types. Useful when the reference is motion or style from another clip rather than a still. Combined cap of 4 with image_urls.

Audio passthrough on demand

Set keep_audio to true to preserve the source soundtrack in the output. Default is off, which is what you want when you plan to score the edit in post.

Standard or Pro output

Std mode renders at 720p for editorial passes and alternate-cut review. Pro mode renders at 1080p for delivery. Three aspect ratios cover most placements.

Best for

Reshoots and revisions

Reprompt the same clip for look, pacing, or subject changes without rebuilding the timeline.

Reference-guided edits with VIDEO elements

Use video elements as conditioning. Useful when the reference is motion or style from another clip, not a still.

Localization with audio preserved

Adjust visuals while keeping the dialogue track. Useful for ads going to multiple regions with the same VO.

Social repurposing

Reframe and restyle clips for different platforms using aspect controls and prompt adjustments.

VFX-style passes via Transform

Heavier restyle or retime when the brief needs more than a colour tweak.

Long-source workflows up to 10 minutes

Most edit endpoints cap at 30 seconds. Omni Edit handles a 10-minute source, which supports trailer cuts and long-form work.

Variants

Two output tracks and two edit modes. Combine them based on resolution and how aggressive the edit needs to be.

Standard

The 720p output mode. Faster turnaround for editorial passes where the cut is not heading to a hero unit yet.

Pro

The 1080p output mode. Use it when the edit is the delivery cut and resolution is the contract.

Reference mode

Treats the source clip as a style or motion guide for the prompted change. Good for edits that should preserve the original feel while the prompt steers a specific change: costume swap, lighting shift, character substitution.

Transform mode

Reshapes the supplied footage more aggressively. Heavier restyle, retime, or scene-level rework. Use it when the edit is a meaningful departure from the source.

Use cases

Re-cut a finished spot for a new region by passing the original ad as video_url, prompting in the new background or signage swap, and keeping audio passthrough on so the VO stays locked. Restyle a brand piece into a different look by switching to Transform mode and passing a reference image of the target style as @image_1. Build alternate cuts for client review without re-shooting by reprompting the same source three different ways and sending the chosen variant on Pro. Apply a VFX-style colour and motion pass to a trailer in one call instead of layering multiple passes in an NLE.
