LPM: Industrial-Scale Generative Video Restoration
Summary
The Large Processing Model (LPM) is a diffusion-based generative framework for photorealistic video restoration, specifically designed for complex, in-the-wild degradations found in user-generated content (UGC). It represents the first generative video restoration model deployed at an industrial scale, notably at Kuaishou. LPM integrates large-scale data engineering, foundation-model training, and efficient inference through an enhanced architecture, progressive training strategy, and temporal-pyramid inference mechanism. This enables high-fidelity, temporally consistent restoration of arbitrarily long videos across diverse content. At Kuaishou, LPM processes videos accounting for approximately 45% of total viewing time, consistently improving quality-of-experience metrics. Furthermore, it reduces bitrate by 20% relative to Kuaishou's in-house codec, yielding annual bandwidth cost savings on the order of hundreds of millions, and has been integrated into products like Kling.
Key takeaway
For MLOps engineers optimizing video delivery on large UGC platforms, LPM demonstrates that generative video restoration is production-ready. You should evaluate diffusion-based models for enhancing video quality and achieving substantial bitrate reductions, potentially saving hundreds of millions in annual bandwidth costs. Consider integrating such models into your processing pipelines to improve user experience and system efficiency.
