Wraith Engine

The media processing engine behind the suite.

Wraith Engine is MediaWR's in-house media processing pipeline for professional media. It powers FORGE, REALTIME and VOX across file-based and live workflows.

Written in house for video, audio and data processing, it is designed to deliver the format coverage, performance and output quality expected in broadcast and post-production environments.

Purpose-built for media
Designed from the ground up for professional video, audio and data processing, with the media pipeline at the centre of the architecture.

Professional format support
Built for the codecs, containers, metadata and standards used across broadcast, post-production and delivery workflows. The table below is not exhaustive and is continually expanded.

CPU and GPU processing
Engineered to make efficient use of modern CPUs and GPUs at every stage of the pipeline.

High quality processing
Processes resolutions from SD to 8K through a full 16-bit image pipeline, with colour-accurate processing including HDR in PQ and HLG. The audio pipeline supports high-bit-depth multichannel processing. Scaling, colour conversion, resampling and format conversion preserve precision, chroma handling and signal integrity throughout.
