A dependency-free (pure standard-library) Python tool that loads the published rate-quality dataset and computes the full BD-rate matrix — HEVC vs H.264, AV1 vs H.264, and AV1 vs HEVC — per content type and as an average, reproducing this article's headline table exactly. BD-rate is computed the way the research recommends: SHAPE-PRESERVING monotone PCHIP interpolation (no overshoot), integration in the LOG10-bitrate domain, integration ONLY over the overlapping quality range (IoU reported, thin

Fora Soft Video Engineering Handbook
This Python tool computes the BD-rate matrix for HEVC, AV1 and H.264 per content type with monotone PCHIP interpolation in the log-bitrate domain over the overlapping quality range. Our seven-volume handbook covers the full video stack; start with Volume 1 for codecs, quality metrics and BD-rate, then Volume 3 for ABR ladders and Volume 6 for AI quality models. Written by Nikolay Sapunov, CEO at Fora Soft.
Need proof that AV1 or HEVC will save bitrate on your own content?
Send us sample clips, and we will run a BD-rate comparison across codecs on your content and estimate the CDN savings. 250+ video products shipped since 2005.
You get a realistic estimate, technical recommendations and next steps. Free, no obligations.
