Lumen · AI Video Enhancer
Built for AI-generated video · YouTube · TikTok · Shorts

Make AI videos
look cinematic again.

Lumen restores blurry 720p clips from Grok, Kling, Veo and Runway — removing compression artifacts, sharpening faces naturally, denoising and upscaling to crisp 1080p, 1440p or 4K. Tuned to survive YouTube's re-encode so your uploads never drop to 480p.
