--- Comment #9 from Jean-Baptiste Mardelle <j...@kdenlive.org> --- The issue was produced in some cases when the video file reported an incorrect aspect ratio. This can be fixed by changing the proxy profile like this: replace this part "-s 640x480" with: "-vf scale=640:-1" This tells ffmpeg to keep aspect ratio -- You are receiving this mail because: You are watching all bug changes.
