--- Comment #1 from Martin Pecka <pe...@seznam.cz> --- I also got this error between steps 3 and 4: Your project file was upgraded to the latest Kdenlive document version, but it was not possible to create the backup copy D:/Download/test3/test4_after_restart_backup0.kdenlive. I do not see this error normally, it was just triggered by the frequent usage of "Save project as". And it shouldn't influnce the usage of proxies, because step 5 still renders fine. -- You are receiving this mail because: You are watching all bug changes.
