@jfml @mo Hey, Thanks! Yes, it is directly the Krita Recorder file posted here. I put this settings (screenshot in attachement) and it is complex to set because of a big bug in the math of the result/preview where the duration in second is always assumed for 30fps. So, because I put 120fps for the input, I have to put them 4 time longer. (eg. 4sec preview for 1sec real). Once like that, I obtain a ~2MB MP4 file.
