Audio Engineering

USB vs XLR: Interface Deep Dive

From budget condensers to professional preamps — understand gain staging, phantom power, and impedance matching for broadcast-quality audio capture.

Compressor Chain for Stream Audio

Build a signal chain that tames peaks, controls noise floor, and delivers consistent loudness across OBS, Voicemeeter, and hardware outboard gear.

Room Acoustics & Mic Placement

Acoustic treatment on a budget: bass traps, diffusion panels, and the cardioid pickup geometry that eliminates room reflections in untreated spaces.

Video Capture & Encoding

Capture Card Selection Guide 2024

HDMI passthrough, 4K capture latency, and PCIe vs USB bandwidth ceiling — a technical breakdown for choosing between Elgato, AVerMedia, and Magewell hardware.

H.264 vs HEVC Encoder Settings

Keyframe intervals, CBR vs VBR, hardware NVENC vs software x264 — configuring your encoder for consistent bitrate at the lowest CPU load possible.

Scene Switching & Transition Design

OBS scene collection architecture — nested scenes, browser sources, and programmatic switching via OBS WebSocket for seamless production transitions.

Camera Lens & Depth of Field Control

Achieving cinematic bokeh on-stream: mirrorless vs webcam sensors, aperture trade-offs, and achieving shallow depth of field without a gimbal rig.

Chroma Key Studio Setup

Greenscreen lighting ratios, distance from the key surface, spill suppression in OBS, and virtual set design that survives 1080p compression artifacts.

Multi-Camera Production Switching

Two-camera setups with Atem Mini, triggered cuts via Stream Deck, and color-matching separate camera sources for a broadcast-quality multicam look.

Streaming Infrastructure

RTMP to SRT Protocol Migration

Why SRT is replacing RTMP as the ingest protocol of choice — packet recovery, latency tuning, and configuring OBS, ffmpeg, and NGINX for SRT ingest.

Self-Hosted NGINX Media Server

Compile NGINX with nginx-rtmp-module, configure HLS segmenting, and serve your own stream without paying for a third-party ingest service.

CDN Edge Caching for Live HLS

Cloudfront + NGINX HLS: segment cache control headers, origin shield configuration, and failover rules for reliable delivery to global audiences.
