Essential Broadcast Engineering Tools and IP Video Calculators

Modern media production involves complex infrastructure, from baseband SDI routing to advanced IP video protocols like SMPTE ST 2110, NDI, and SRT. Transitioning broadcast facilities to IP introduces new challenges in timing, bandwidth management, and network architecture. Our suite of broadcast engineering tools is designed to help System Integrators and Production Engineers calculate exact requirements for data payloads, precise A/V synchronization, and QoS configurations.

Whether you are budgeting network switch capacity using our IP Video Bandwidth Calculator, troubleshooting dropped packets over public internet with our SRT Latency Calculator, or planning optical runs with the Fiber Optic Link Budget Calculator, these experimental utilities provide quick technical references without relying on guesswork. Proper planning of 10GbE and 25GbE networks prevents costly bottlenecks during live multicamera events.

XR and Virtual Production Planners

Virtual Production (VP) using Unreal Engine and LED volumes requires millimeter-perfect calibration between real-world cinema cameras and virtual sensors. Misconfigurations lead to visible rendering artifacts, bad frustum scaling, and tracking latency mismatch. We developed dedicated XR production calculators to bridge the gap between physical camera technicals (like focal length, filmback sensor size, and Depth of Field) and Unreal Engine's nDisplay logic.

Use the Camera Depth of Field Calculator to establish hyperfocal limits that keep physical talent in sharp focus while sufficiently blurring the LED wall to eliminate cross-hatch moiré patterns. Simultaneously, map your camera tracking data delays, render pipeline processing, and LED processor frame buffering with our Tracking Latency Calculator to implement exact genlock compensations.

Audio over IP (AoIP) and Dante Synchronization

Audio network design dictates that PTP (Precision Time Protocol) clocking remains absolute. Mixing Dante and AES67 endpoints requires explicit switch configuration. Our Dante & AES67 Switch Configurator generates exact QoS DSCP mappings to prioritize network clock sync over generic TCP data. Combined with the Audio Latency Calculator to convert samples to milliseconds, and the visual A/V Sync Calibrator, audio engineers can align disparate incoming video sources—like vMix callers, TriCaster inputs, or remote NDI feeds—perfectly to the house audio console delay.
