Background blur runs a fast segmentation model on every frame to find the person, then blurs or replaces the rest. Quality hinges on clean edges around hair and hands and on keeping latency low enough not to lag the call.

AI for Video: A Complete Guide to Intelligence in Video Products: From Real-Time Pipelines and Agents to Serving, Cost, Compliance, and Verticals
Background blur has to segment every frame within the call's latency budget, and ragged edges around hair and hands are what users notice. Volume 7 covers real-time AI in detail: call latency, where AI fits into a WebRTC pipeline, serving with TensorRT, and cost per stream-hour, so background blur runs smoothly on the devices your users have. Written by Nikolay Sapunov, CEO at Fora Soft.
Background blur lagging the call or leaving ragged edges on low-end devices?
We will profile your segmentation pipeline and send a background blur plan with model choice, WebGPU or WASM placement and frame budget per device. 250+ video products shipped since 2005.
