Modify Video by Luma AI

Product Introduction

1. Modify Video by Luma AI is a post-production video editing tool that enables granular control over style, character, and environment while preserving the original motion, performance, and camera dynamics. It uses advanced AI to reinterpret scenes, swap elements, or redesign entire frames without requiring reshoots or manual tracking.
2. The core value lies in eliminating the need to restart workflows when altering creative decisions, allowing professionals to iterate on environments, textures, and characters while retaining the integrity of performances and camera movements. It bridges the gap between raw footage and final renders by offering director-grade flexibility in post-production.

Main Features

1. Motion & Performance Capture + Puppeteering: Extracts full-body, facial, or lip-sync motion data from any video to animate new characters, props, or camera paths. This enables seamless integration of CG creatures with live-action actor performances or stylized character variants synchronized to original movements.
2. Restyle, Retexture, and World Swapping: Transforms scene aesthetics while preserving motion and framing, such as converting a garage into a spaceship or shifting footage from low-poly to photorealistic. The AI maintains temporal consistency across frames, ensuring smooth transitions between styles or environments.
3. Isolated Motion VFX & Scene Element Edits: Edits individual elements like wardrobe, props, or skies without affecting the entire shot. This allows for in-scene aging of characters, color correction for continuity, or adding visual effects like UFOs without green screens or manual tracking.

Problems Solved

1. Main pain point addressed: Traditional video editing requires restarting workflows for major changes, leading to wasted time and resources. Modify Video eliminates this by enabling non-destructive, AI-driven transformations of scenes, characters, and objects in post-production.
2. Target user group: Professional creatives in film, VFX, advertising, and game development who require high-fidelity edits without compromising motion or performance data. It also serves indie creators needing cost-effective alternatives to reshoots.
3. Typical use case scenarios: Previsualization for pitch decks, client-driven style changes in commercials, fixing continuity errors in films, or experimenting with character designs in animated sequences without re-rendering entire scenes.

Unique Advantages

1. Difference from similar products: Unlike prompt-only tools like Runway Gen-2, Modify Video uses performance signals (pose, facial tracking, scene structure) to preserve critical motion data while editing, ensuring outputs align with director intent.
2. Innovative features: Structured presets (Adhere, Flex, Reimagine) allow users to define transformation intensity, from subtle retexturing to full-scene reinterpretation, such as mapping humans to non-humanoid creatures.
3. Competitive advantages: Native 16:9 (720p) resolution support, prompt-optional visual guidance, and multi-variant outputs for rapid style exploration outperform competitors in temporal consistency and motion retention, as validated by blind evaluations against Runway V2V.

Frequently Asked Questions (FAQ)

1. What is the maximum video duration supported? Modify Video currently supports clips up to 10 seconds in Dream Machine: Ray 2, optimized for high-quality motion preservation and style transfer without performance degradation.
2. How does it preserve facial expressions during transformations? The AI analyzes performance signals like lip sync and facial tracking data, isolating these elements from background or stylistic changes to maintain emotional authenticity.
3. Can I use my own visual references instead of prompts? Yes, Modify Video allows users to guide outputs with first-frame images, style boards, or existing footage, bypassing text prompts for precise creative control.
4. What file formats are supported for input and output? The tool accepts common video formats (MP4, MOV) and exports in 16:9 (720p) resolution, ensuring compatibility with standard editing pipelines.
5. How does the Reimagine preset handle non-humanoid characters? By prioritizing creative freedom, the preset uses advanced rigging algorithms to map human motion data to fantastical forms (e.g., monsters), retaining original movement logic while altering visual design.
