Overview
The speaker explains their process for generating consistent characters in Runway V3 for a documentary, covering visual and voice consistency, and techniques for removing unwanted subtitles using AI tools.
Creating Consistent Visual Characters
- Runway V3 currently lacks character reference support, so the process relies on detailed prompt engineering.
- Used Google's Whisk tool to generate an image and a robust prompt from the AI's image analysis.
- Transferred the image description and original prompt into Gemini, instructing it to focus on the character's facial features.
- Requested a consistent character template, resulting in a core prompt for visual appearance and personality.
- Maintained consistency by using the same detailed character description across all prompts.
Ensuring Consistent Character Voice
- Asked Gemini to suggest a character name ("Aram") and detailed voice description for use in prompts.
- Desired a consistent, slightly raspy and thoughtful voice for the character.
- For audio, combined clips into a 10-second sample and used 11 Labs to clone the character’s voice, aiming to minimize unwanted accent variations.
- Used text-to-speech in 11 Labs to fine-tune or replace inconsistent voice outputs for better uniformity.
Removing Captions/Subtitles from Videos
- Noted inconsistent results with caption removal when generating videos using Gemini.
- Used Runway’s inpainting tool to manually brush out captions, producing acceptable but sometimes noticeable edits.
- Found Cap Cut’s AI removal tool more effective for erasing captions, especially in complex visual areas.
V3 Video Generation Tips
- Compared V3 fast mode (20 credits) to quality mode (100 credits), noting that fast mode sometimes yields unique and even preferable results.
- Explained how to switch between fast and quality modes in Runway V3 settings.
Final Advice and Resources
