What is Whisper Thunder?
Whisper Thunder is an AI video generator powered by Runway Gen-4.5 that converts still images into 5- or 10-second HD videos. It accepts JPG, PNG, WEBP and GIF inputs and exports 720p or 1080p video optimized for social platforms. The interface uses natural-language prompts for prompt-based motion control and precise prompt adherence.
Gen-4.5 outputs support photorealistic and stylized animation, complex scenes, detailed compositions, realistic physics, and expressive character motion. The workflow is a three-step process—upload image, add prompt, download video—suited to photographers, content creators, social media managers, marketers, and digital artists.
