Overview

WATT-IF is an AI-powered mobile application that transforms the way video creators handle lighting. It functions as a pocket-sized lighting studio, allowing users to adjust and enhance the lighting of their videos after they have been recorded. Using advanced machine learning algorithms, WATT-IF analyzes the video frames, identifies light sources and subjects, and enables precise control over lighting direction, intensity, color temperature, and softness. Users can simply tap and drag on the screen to reposition virtual lights, achieving professional studio-quality results without the need for expensive physical lighting equipment. The app leverages computational photography techniques to deliver realistic relighting effects in real time, making it accessible to both amateur and professional videographers.

In addition to basic relighting, WATT-IF offers a suite of creative controls. Users can simulate dramatic studio setups, correct poor lighting conditions, add accent lights to specific areas, or completely change the mood of a scene. The AI handles complex scenarios such as mixed lighting, skin tone preservation, and dynamic backgrounds. The app provides intuitive presets for common scenarios like interviews, product shots, and social media content, while also offering manual sliders for fine-tuning. With its non-destructive editing workflow, users can experiment freely without altering the original footage.

WATT-IF is designed for on-the-go content creators who need high-quality video production directly from their smartphones. The app integrates with popular video editing and sharing platforms, allowing seamless export. Its lightweight architecture ensures smooth performance even on older devices, and regular updates introduce new AI models for improved accuracy and speed. The paid subscription model provides access to premium features such as 4K support, advanced color grading, and cloud storage for projects.

The technology behind WATT-IF includes deep neural networks trained on extensive datasets of lighting scenarios, enabling it to understand 3D geometry and reflectance from a single 2D video stream. This means that even with a simple selfie video, users can add professional lighting as if they had a full studio. The app's interface is minimalist and user-friendly, catering to beginners while still offering depth for experienced editors.
