--- Comment #9 from Adam Fontenot <adam.m.fontenot+...@gmail.com> --- Created attachment 165948 --> https://bugs.kde.org/attachment.cgi?id=165948&action=edit illustration of crf 20 vs 31 in a fullscreen recording As a quick illustration, I've taken two fullscreen (60 fps 1080p) screencasts with comparable details (I scrolled up and down this page in my browser for a bit), at both CRF 31 (the default) and CRF 20 (with my patch). The result illustrates the way that VP9 cheats on flat fields quite well. This area of the screen shown in the image is basically static in the video, and contains large regions of a single color. The encoder cheats a lot here, with a result that is visibly much worse with CRF 31. For common screencast use cases, like recording bugs and features, this is a worst case scenario of sorts, since you'd like to see relatively crisp looking text and icons. -- You are receiving this mail because: You are watching all bug changes.
