Introduction

The streaming industry faces an unprecedented challenge: Gen-AI video content is exploding in volume while CDN costs continue to spiral upward. A breakthrough Q3 2025 case study from an OTT startup demonstrates how combining Sima Labs' SimaBit preprocessing engine with strategic multi-CDN routing can slash total bandwidth costs by 43%. This comprehensive analysis reveals the exact methodology, implementation details, and measurable results that transformed their streaming economics.

Sima Labs' SimaBit AI preprocessing engine reduces video bandwidth requirements by 22% or more while boosting perceptual quality (Sima Labs). The engine integrates seamlessly in front of any encoder—H.264, HEVC, AV1, AV2, or custom solutions—allowing streamers to eliminate buffering and shrink CDN costs without disrupting existing workflows (Sima Labs).

The Challenge: Gen-AI Video's Bandwidth Explosion

Rising Content Complexity

Gen-AI video presents unique compression challenges that traditional encoding approaches struggle to handle efficiently. Unlike natural video content, AI-generated footage often contains:

• Synthetic textures that don't compress well with standard algorithms

• Rapid scene transitions that increase bitrate spikes

• Complex visual effects requiring higher quality preservation

• Diverse content types spanning from photorealistic to stylized animation

These characteristics result in significantly higher bandwidth requirements compared to traditional video content, directly impacting CDN costs for streaming platforms.
