Showmax switches to next‑gen codecs and rewrites the encoding pipeline so a single 90‑minute movie goes from taking multiple hours (often up to 3.5× video duration) to as low as 0.12× duration by splitting mezzanine files into chunks and running parallel chunk workers that transcode and reassemble. Uses ffmpeg, a CMS to set priorities, and Unified Streaming filters; outcome is ~30% less delivered data, far faster job prioritization, and finer device‑codec control.
