Modify Video – Generative Video Editing Model

What is Modify Video?

Modify Video is Luma AI’s state-of-the-art generative video editing model designed for high-fidelity transformations without reshooting. By leveraging advanced pose, facial and lip-sync tracking, it maintains full-body motion consistency while enabling scene swaps, environment retexturing and style restyling. Creators and developers can generate multiple variants from a single clip, each preserving natural temporal flow and actor performance signals.

Key Features

• Full-Body & Facial Tracking: Retains original actor movements, expressions and lip-sync for seamless edits.
• Temporal Consistency: Keeps frame-to-frame continuity, minimizing flicker and jitter in output.
• Multiple Modes:
  • adhere_1/adhere_2/adhere_3 – faithful, subtle edits
  • flex_1/flex_2/flex_3 – balanced transformations
  • reimagine_1/reimagine_2/reimagine_3 – creative overhauls
• Prompt-Driven Styles: Use natural-language instructions (e.g., “make it vintage”) to guide restyling.
• First-Frame Guidance: Supply a custom first frame image URL to anchor the visual style.
• Native Resolution Support: Outputs at the same resolution as the source clip (MP4).

Best Use Cases

• Scene Replacement: Swap backgrounds or entire sets in short clips under 30 seconds.
• Creative Restyling: Transform modern footage into vintage, cinematic or genre-specific looks.
• Lip-Sync Corrections: Fix dialogue sync issues while preserving actor performance.
• Color Grading & Lighting Adjustments: Apply consistent color palettes and dynamic lighting effects.
• Director-Grade Edits: Iterate on multiple stylistic variants quickly for pre-visualization and dailies.

Prompt Tips and Output Quality

1. Start Simple: Begin with clear prompts like “add neon lights” or “cinematic teal-orange grade.”
2. Adjust Mode:
   • For minimal adjustments, choose adhere_1.
   • For bold, artistic changes, use reimagine_1.
3. Leverage First Frame: Supply a stylized image via first_frame_url to guide overall look.
4. Clip Length: Keep source videos under 30 seconds for optimal processing speed.
5. Iterate Variants: Run the same prompt with different modes to compare subtle vs. dramatic effects.

FAQs

Q: What video formats are supported?
MP4 clips (under 30 seconds) are recommended for reliable ingestion and native resolution outputs.

Q: How do I choose between adhere, flex, and reimagine modes?
Use adhere modes for faithful edits, flex for moderate stylizations, and reimagine for full creative overhauls.

Q: Can I preserve lip-sync accuracy?
Yes—Modify Video’s facial tracking maintains lip-sync motion even when retexturing environments.

Q: Is a custom first frame required?
No. It’s optional but highly effective for guiding strong stylistic changes.

Q: How do I guide specific edits?
Set the prompt parameter with natural-language instructions (e.g., “make it look like film noir”) to direct the AI.
