Luma Modify Video API for Motion VFX & Scene Restyling

Luma Modify Video, developed by Luma Labs, is an AI-powered video transformation tool that reimagines what’s possible in post-production. Unlike traditional workflows that demand reshoots, green screens, or heavy VFX pipelines to alter a scene, Modify Video allows you to change the world around your subject—while preserving the integrity of the original motion, performance, and camera work. Built on the powerful Ray 2 , it enables seamless edits such as environment swaps, lighting adjustments, texture restyling, and even character transformations. Whether you're turning a living room into a futuristic cockpit or subtly adjusting wardrobe for continuity, Modify Video gives you full creative control without compromising what makes your footage work. It’s a new standard for professional-grade, motion-aware video editing—designed to unlock limitless possibilities from a single shot.

What Makes Luma Modify Video a Game-Changer in AI Video Editing

Luma Modify Video offers three structured modification modes—Adhere, Flex, and Reimagine—each designed to give creators precise control over how much the original video is altered. Whether you're making subtle adjustments or embarking on full-scene reinvention, these modes ensure your vision is preserved and elevated with AI precision.

The Adhere mode is ideal for light-touch edits that maintain the original video’s structure, motion, and aesthetic integrity. It focuses on subtle changes like retexturing, minor lighting adjustments, or wardrobe tweaks—perfect for continuity fixes or light stylization without altering core elements. Adhere preserves every nuance of the source video, making it the go-to choice for professional-grade polish with minimal disruption.

Adhere: Subtle Enhancements, Maximum Fidelity

Flex strikes a balance between fidelity and transformation, offering moderate creative freedom while retaining key aspects of the original footage. This mode allows for significant style shifts—such as changing environments, time of day, or material properties—while keeping the character’s performance, facial expressions, and motion intact. It’s an ideal middle ground for content creators, filmmakers, and VFX artists seeking visual impact without losing narrative cohesion.

Flex: Creative Balance Between Realism and Imagination

Reimagine mode unleashes the full creative potential of Luma’s Modify Video API. It enables complete visual reimagination, allowing characters, props, and environments to be transformed into entirely new forms—such as turning a human into a creature, or a mundane street into a sci-fi cityscape. This mode is best suited for projects that demand bold, artistic reinterpretation, and is particularly powerful for concept development, world-building, or experimental storytelling.

Reimagine: Full Scene Reinvention with AI Freedom

Choosing the Right Modification Mode in Modify Video: Adhere, Flex, or Reimagine

The Luma Modify Video API is built to capture and preserve intricate performance details—such as full-body motion, facial expressions, and lip-sync—ensuring the original timing, emotion, and choreography remain untouched. This capability allows you to drive new characters or visual elements using the same expressive data, all while maintaining the authenticity of the original take. It’s a motion-aware editing foundation that brings AI-driven workflows to a professional level.

Precision Motion Preservation with Luma Modify Video API

Modify Video empowers users to reimagine entire scenes through advanced restyling, retexturing, and world swapping—without affecting the original motion or performance. Turn a parking garage into a neon-lit spaceship, shift a sunny afternoon into a stormy night, or transform live-action footage into stylized animation. Thanks to the Ray 2, these changes occur with visual coherence and spatial consistency, making it possible to explore radically different aesthetics while keeping the character and camera exactly as intended.

Restyle, Retexture, and World Swapping with Modify Video

Luma Modify Video supports Motion VFX and localized scene edits with surgical precision. Whether it’s changing a shirt’s texture, replacing a specific prop, or adding fire or glowing light to a moving object, this feature allows you to isolate and modify elements frame by frame—without tedious rotoscoping or full-scene reprocessing. The system intelligently tracks motion and context, enabling clean integration of dynamic effects into the scene while maintaining original performances.

Isolated Motion VFX and Element-Level Editing in Luma Modify Video

The Modify Video API gives creators structured control over the degree of transformation through its three intelligent presets: Adhere, Flex, and Reimagine. Each mode balances creative freedom with visual fidelity—ranging from light surface-level changes to full-scene reinventions. This framework makes it easy to adapt the tool to different creative goals, whether you’re maintaining continuity in post-production or crafting experimental visual narratives from scratch.




Adaptive Creative Modes in the Modify Video API

Key Features of Luma Modify Video: From Motion VFX to World Swapping

Both Luma Modify Video and Runway Aleph are powerful AI-driven video tools, but they serve distinct creative needs. Runway Aleph focuses on comprehensive in-context video editing, excelling at tasks like object removal and camera manipulation. In contrast, Luma Modify Video is purpose-built for high-fidelity video restyling, preserving motion and performance while transforming scenes, textures, or characters. If your project demands precision in performance retention and creative visual reimagination, Luma offers a longer clip limit, structured transformation modes, and superior motion fidelity.

Luma Modify Video vs. Runway Aleph: Which AI Video Editing Tool Fits Your Workflow?

To begin using the Modify Video API, visit Kie.ai and create an account or log in. Once inside your dashboard, navigate to the API section to generate your unique Modify Video API key. This key is required for authenticating all API requests and accessing both the Playground and deployment environments.

Step 1: Register and Get Your Modify Video API Key

In the Playground, you can quickly experiment with different transformations—no coding required:
- Paste a Video URL to define your source footage.
- Optionally provide an Image URL to serve as a visual style or first-frame reference.
- Enter a Prompt to describe the visual transformation you'd like (e.g., “an ancient temple at sunset”).
- From the Mode dropdown, choose how far you want the scene to change:
   Adhere (1–3): Minimal edits, such as texture and lighting tweaks.
   Flex (1–3): Balanced changes, keeping core structure while shifting aesthetics.
   Reimagine (1–3): Full-scene re-creation—ideal for fantasy, surrealism, or animation-style remapping.

Step 2: Test Your Video in the Playground

When you're ready to build, use your API key to connect the Modify Video API to your application. You can send HTTP requests with your video link, optional prompt, reference image, and selected mode. The API works with any programming language that supports HTTP—like Python, JavaScript, or others.

Step 3: Integrate the Modify Video API into Your Project

Send a short video (up to 10 seconds), and describe how you'd like to transform it. You can change the style, setting, lighting, or even reimagine the entire world—while keeping the original motion and performance intact. Just choose a transformation mode (Adhere, Flex, or Reimagine) and submit your request.

Step 4: Generate Modified Videos from Your Input

Once your video is processed, the API will return a link to the modified version. You can view it, download it, or use it directly in your product or workflow. Each result also includes basic metadata like duration, resolution, and the applied mode.

Step 5: Access and Use the Resulting Video

Getting Started with Modify Video API on Kie.ai

Avoid stating what you don’t want—instead, describe exactly what you do want to see. For instance, use “a glowing city street at dusk with neon signs” instead of “do not make it daytime.” This style helps the model align with your creative intent. Think of it as directing a scene—include lighting, mood, environment, and tone to give the AI a concrete visual direction.

Lead with clear, visual, and positively framed prompts

When provided with a reference image, the API can root the transformation in a specific aesthetic or first-frame anchor. You can choose whether it's applied as a style reference or a literal start frame, making it a powerful tool to guide retexturing, world changes, or visual mood.

Use reference images to guide style and visual clarity

Your source video should ideally be no longer than 10 seconds, filmed with minimal camera shake and clear lighting. A plain, uncluttered background helps the AI isolate subjects and track motion effectively. This foundation ensures accurate preservation of motion while enabling seamless visual transformation.

Prioritize clean, stable footage with clear subjects
