--- Comment #11 from alcinos <french.ebook.lo...@gmail.com> --- Thank you very much with the in-depth exploration! When you don't accept to create the profile, or switch to an existing profile, it means that potentially the fps of the project and the fps of your video samples don't match. My theory, based on what you show, is that the fps conversion math (used for example to compute the length of the clips in frames), will create small but real rounding errors, and when you repeat that over and over the errors will compound. I'm a bit short on time right now but will definitely take a look soon, if confirmed it would be a serious bug. To be sure I reproduce exactly what you did, would you mind giving me the default fps of your projects in kdenlive? It should be displayed in the title of the app when you open a fresh kdenlive. -- You are receiving this mail because: You are watching all bug changes.
