--- Comment #2 from Jean-Baptiste Mardelle <j...@kdenlive.org> --- Oh, somehow I forgot to post my comment on this issue. I think the bad performance you are experiencing in timeline is caused by the track's composite transition, which are causing a huge performance issue. Can you try disabling them to see if it changes something ? Looking at your project file, it looks like only proxies are used in timeline. -- You are receiving this mail because: You are watching all bug changes.
