--- Comment #9 from Jean-Baptiste Mardelle <j...@kdenlive.org> --- I need more infos to understand the problem. I need you to check those things: 1 - Make sure Kdenlive works without movit: If you disable movit in Kdenlive settings, can you correcty open and play a video clip 2 - Make sure MLT works with Movit: in a terminal, type: melt myclip.mp4 .glsl=1 -attach movit.saturation saturation=0 -consumer xgl Replace myclip.mp4 with any clip you have. It should play your clip in black and white Please let me know the results of steps 1 and 2 -- You are receiving this mail because: You are watching all bug changes.
