A one-page printable landscape reference that maps every common video artifact (blocking, ringing, mosquito noise, blur, banding, color bleeding, judder/stutter, freezing/tiling) to what it looks like, where it is born in the pipeline, which objective metric catches it or is blind to it, and the fix — with the banding and temporal blind spots highlighted. Built for keeping beside a QC dashboard.

Fora Soft Video Engineering Handbook
This field guide maps blocking, ringing, mosquito noise, blur, banding, color bleeding, judder and freezing to their look, origin, the metric that catches them and the fix. Our seven-volume handbook covers the full video stack; start with Volume 1 for compression artifacts and quality metrics, then Volume 3 for delivery and Volume 6 for AI quality models. Written by Nikolay Sapunov, CEO at Fora Soft.
Chasing compression artifacts that your quality metrics do not flag?
Send us problem clips, and we will identify each artifact, trace it to the pipeline stage and suggest metric and encoder fixes. 250+ video products shipped since 2005.
