A dependency-free (pure standard-library) Python tool that loads the per-content rate-quality dataset and computes BD-rate (HEVC, AV1 over H.264 and AV1 over HEVC) for every content type, the spread across content types, the content-complexity table (anchor bitrate at VMAF 93 with ITU-T P.910 SI/TI), and a CATALOGUE-WEIGHTED saving for any content mix via --mix (e.g. --mix animation=60,screen=20,film=20). Reproduces this article's per-content table and worked mixes exactly and matches article 7.

Fora Soft Video Engineering Handbook
This Python tool computes BD-rate for HEVC and AV1 per content type, the content complexity table with SI and TI, and a catalogue-weighted saving for your own content mix. Our seven-volume handbook covers the full video stack; start with Volume 1 for codecs and quality metrics, then Volume 3 for ladders and delivery and Volume 6 for AI quality models. Written by Nikolay Sapunov, CEO at Fora Soft.
Want to know how much AV1 or HEVC will save on your mix of animation, sports and film?
Tell us your catalog mix, and we will run a content-weighted BD-rate estimate and translate it into storage and CDN savings. 250+ video products shipped since 2005.
You get a realistic estimate, technical recommendations and next steps. Free, no obligations.
