Idea
Generative video restoration platform improving quality and reducing bandwidth costs for large-scale user-generated content platforms.
Research Paper
Core Innovation
This paper introduces LPM, the first industrial-scale generative video restoration model using a diffusion-based framework. It combines large-scale data engineering, foundation-model training, and a temporal-pyramid inference mechanism to restore arbitrarily long videos with high fidelity and temporal consistency, outperforming prior restoration methods in scalability and quality.
Why It Matters
Video platforms face diverse, complex degradations in user-generated content that degrade viewer experience and increase delivery costs. LPM enhances video quality consistently while reducing bitrate, lowering bandwidth expenses by hundreds of millions annually. Its scalability and low serving cost enable broad adoption and integration into consumer-facing products, transforming video processing workflows.
Market Size (TAM)
$20–50B TAM for video streaming and content delivery; $2–10B SAM from social media and streaming platforms. Driven by rising video consumption and demand for cost-efficient quality enhancement.
Potential Customers & Pain Points
- Video streaming platforms – Need to improve video quality and reduce bandwidth costs
- Social media companies – Require scalable restoration for diverse user content
- Content delivery networks – Seek to optimize bandwidth usage
- Consumer app developers – Want cost-effective video enhancement features.
Business Model
SaaS or API-based licensing to video platforms and content delivery networks, with tiered pricing based on volume and feature set; potential white-label integration for consumer apps.
Competitive Landscape

- Cost-benefit analysis demonstrating bandwidth savings
- User feedback and engagement metrics post-integration
Research Paper Overview
LPM: Industrial-Scale Generative Video Restoration
Summary
LPM is a diffusion-based generative framework for photorealistic video restoration addressing complex degradations in user-generated content. Deployed at Kuaishou, it processes nearly half of total viewing time, improving video quality and reducing bitrate by 20%, enabling significant bandwidth cost savings and scalable integration into consumer products.
