A one-page printable reference that maps each content type and edge case (film grain, high motion, 60 fps, dark/HDR, banding, chroma, screen content/text, animation, enhancement gaming) to why the objective score lies, which metrics are affected, and the detector or check to add instead — plus a short 'before you trust a score' checklist. Built for keeping beside a quality dashboard.

Fora Soft Video Engineering Handbook
This metric blind-spot field guide sits beside a quality dashboard and shows where VMAF and PSNR mislead: film grain, high motion, dark HDR scenes, banding and screen content. Our seven-volume handbook covers the whole video stack; start with Volume 1 on quality metrics, HDR and compression, then Volume 6 for AI models and Volume 3 for QoE monitoring. Written by Nikolay Sapunov, CEO at Fora Soft.
