--- Comment #33 from Jean-Baptiste Mardelle <j...@kdenlive.org> --- The thing is that in your DebugView startup log, you have 130 lines like: plugin not available: "avfilter.aecho" Normally, you should only have like 29 lines of it, because some avfilters are not supported. This means that MLT cannot correctly load the avformat module (its module interfacing with FFmpeg). So I agree that the issue is probably not related to your video files, but there is something on your system that prevents MLT to correctly communicate with FFmpeg. Comparing the 23.x with 24.x installs, I found a difference in the way MLT libraries are installed. In 23.08, the 2 MLT libraries libmlt-7.dll and libmlt++-7.dll were in 2 locations: C:\Program Files\kdenlive\bin and C:\Program Files\kdenlive\lib In Kdenlive 24.x, these 2 libraries are only in: C:\Program Files\kdenlive\bin Could you try with a Kdenlive 24.12 install to copy these 2 libraries from C:\Program Files\kdenlive\bin to C:\Program Files\kdenlive\lib and check if it makes a difference ? -- You are receiving this mail because: You are watching all bug changes.
