LTX-2 Retake: Directable AI Video Editing on RunDiffusion

LTX-2 Retake lets creators regenerate selected moments within a video while preserving continuity. You can reshape tone, dialogue, or motion without re-rendering entire scenes, making Runnit a powerful tool for directable AI filmmaking.
LTX-2 Retake: Directable AI Video Editing on RunDiffusion


The newly launched feature LTX-2 Retake on LTX Studio brings real directorial control to AI-generated video. Instead of re-rendering a full scene when something needs changing, Retake lets you selectively edit while preserving everything else: performance, setting, lighting, motion, and context. For creators, marketers, and studios using AI for video production, this is a major win for flexibility and efficiency.


What Is Retake?

Retake is the first AI-directing tool designed to let you:

  • Rephrase dialogue without re-rendering the entire shot.
  • Redirect emotion or action in a specific moment.
  • Modify beginnings or endings of a take.
  • Produce alternate versions (different pacing, tone, framing) from a single base shot.

You pick a segment typically between about 2 to 16 seconds and Retake regenerates only that portion, while the rest of the shot stays intact.

This is not a trim tool. It’s not a full re-render. Retake is a “directorial redirection” tool everything outside the edited moment remains coherent and continuous.

Let's see an example.

Why Retake Matters: Flexibility, Speed, and Creative Control

Cut Costs & Save Time

Traditional fixes mean re-shoots, rerenders, or full regenerations. Retake lets you make small changes — dialogue, emotion, camera moment without scrapping an entire shot. This saves time, reduces compute cost, and avoids losing all other good elements of a scene. It is cheaper to use LTX-2 Retake to edit a VEO 3.1 Fast than try to get the same generation again.

Iterate Quickly on Feedback

Need to change a line after feedback? Want a different emotional tone? Retake allows for fast iteration recreate only what needs changing, while keeping performance, background, lighting, and continuity intact. Great for marketing, brand videos, or collaborative creative reviews.

Creative Experimentation

Alternate endings, emotion changes, different camera actions, or pacing tweaks — Retake enables creative experimentation within the same take. You can generate multiple variants from a single source act, giving flexibility for A/B testing or narrative branching.

Non-Destructive Editing in AI Video

Retake unlocks a non-destructive editing workflow: you don’t need to throw away a full shot because of one line or a small visual/acting issue. That’s powerful for teams working in AI-powered filmmaking pipelines.

How Retake Works

Feature Description
Edit Scope 2–16 second segments within a shot
Continuity Surrounding motion, lighting, and frames remain unchanged to preserve context
Output Format 1080p output (with downscaling if 4K input)
Use Cases Dialogue rephrasing, emotional retakes, alternate endings, brand A/B test variations, post-production fixes

Who Benefits Most from Retake

Brands & Agencies

  • Adjust messaging or tone after reviewing a cut.
  • Test multiple call-to-action versions or dialogue lines from the same footage.
  • Save on reshoots, speed up feedback loops, and maintain brand consistency.

Filmmakers & Post-Production Teams

  • Fix emotional beats or pacing after previewing.
  • Explore alternative directions without reshooting.
  • Save cost and time while preserving performance and continuity.

Creative Studios & Content Creators

  • Iterate visuals quickly for different social formats or platforms.
  • Experiment with tone, camera direction, and acting takes inside the same shot.
  • Bring flexibility to AI-driven video pipelines.

Limitations & Things to Keep in Mind

  • Retake currently works for short segments (up to 16 seconds) not full-length films.
  • Output is limited to 1080p if input was 4K (downscaled).
  • Because the tool regenerates frames, very complex scenes or heavy VFX might require manual review post-edit.
  • Continuity depends on how well the surrounding frames match the regenerated segment good lighting, stable camera, and consistent motion help.

What This Means for Cloud-Based AI Video Workflows

Retake transforms how teams work with AI-generated video. Instead of treating each shot as final, Retake encourages experimentation, letting creators branch, iterate, and refine without redoing the whole scene. For platforms like RunDiffusion-style cloud workflows or integrated AI studios, this kind of editing flexibility speeds up production and lowers risk.

If you combine Retake with tools that offer consistent scene generation, storytelling, and asset management (like LTX Studio), you get:

  • Faster turnaround times
  • Reduced compute and production cost
  • More creative options per shot
  • Better adaptability to feedback and iterative design

Why Retake Matters

Retake introduces something new to AI filmmaking:
the ability to direct, not just generate.

Traditional AI video systems required re-rendering entire shots to make small changes. Retake solves this by letting you:

  • Preserve what works
  • Modify only what you need
  • Act on feedback immediately
  • Iterate faster and with greater creative precision

It helps creators move from “close enough” to intentional, directable storytelling, where nuance, pacing, and emotion truly matter.
