Quantifying VMAF Gains with SimaBit: Netflix Open Content, YouTube UGC & OpenVid-1M Results
Introduction
Video streaming quality has become the defining factor in user experience, with buffering and poor visual quality driving viewer abandonment across platforms. As the global streaming media services market is projected to grow from USD 11,068.7 Million in 2025 to USD 52,198.0 Million by 2035, at a CAGR of 16.8%, the pressure to deliver high-quality content while managing bandwidth costs has never been greater (Future Market Insights). Traditional approaches to bandwidth optimization often sacrifice perceptual quality, leaving engineers struggling to balance user satisfaction with operational costs.
This comprehensive analysis presents quantified VMAF (Video Multimethod Assessment Fusion) improvements achieved through SimaBit, Sima Labs' AI preprocessing engine, across three distinct content corpora: Netflix Open Content, YouTube UGC, and OpenVid-1M. Our testing demonstrates consistent VMAF score improvements of +3 to +6 points while achieving 22% bandwidth reduction, even under challenging network conditions with WAN 2.2 jitter (Sima Labs). These results provide concrete benchmarks for engineering teams evaluating AI preprocessing solutions and justify preprocessing budget allocations with measurable quality metrics.
The VMAF Advantage: Why Perceptual Metrics Matter
VMAF has emerged as the gold standard for video quality assessment in streaming applications, offering superior correlation with human perception compared to traditional metrics like PSNR. Netflix's tech team popularized VMAF as a comprehensive quality metric that considers multiple factors including detail preservation, temporal consistency, and artifact visibility (Sima Labs). Unlike PSNR, which measures pixel-level differences, VMAF accounts for the human visual system's sensitivity to different types of distortions.
The importance of perceptual quality metrics becomes evident when examining user behavior data. Research shows that viewers abandon streams within seconds when quality drops below acceptable thresholds, making VMAF scores directly correlatable to engagement metrics and revenue retention. Video conferencing systems often provide poor user experience when network conditions deteriorate, as current video codecs cannot operate at extremely low bitrates (arXiv). This challenge extends beyond conferencing to all streaming applications where bandwidth constraints impact quality.
Modern AI-driven video enhancement techniques leverage deep learning-based super-resolution models, optical flow estimation, and recurrent neural networks (RNNs) to improve video quality while maintaining computational efficiency (JISEM Journal). These approaches address traditional video processing limitations including low resolution, motion artifacts, and temporal inconsistencies that plague real-time streaming environments.
