It is usually recommended to capture your screen using lossless mode in libx264 and then re-encode the output to avoid the higher encoding cost during capture. However, if you're planning on editing the screencast with Kdenlive then huffyuv may be more editor friendly (I haven't tried lossless H.264 with Kdenlive): $ ffmpeg -f alsa -i default -f x11grab -r 25 -s 1280x720 \ -i :0.0+320,180 -vcodec huffyuv -acodec pcm_s16le output.mkv > Incompatible pixel format 'bgra' for codec 'libx264', auto-selecting > format 'yuv420p' That is just an info message, and not an error. ------------------------------------------------------------------------------ Master Visual Studio, SharePoint, SQL, ASP.NET, C# 2012, HTML5, CSS, MVC, Windows 8 Apps, JavaScript and much more.
