--- Comment #11 from Jean-Baptiste Mardelle <j...@kdenlive.org> --- Thanks for your report. From the log, I would say that your source video file is corrupted: [mpeg2video @ 0x7fcd9819a900] Invalid frame dimensions 0x0 Could you try to remux the source file with FFmpeg ? In a terminal, type: ffmpeg -i yoursource.m2t converted.mp4 -vcodec copy -acodec copy This will create a "converted.mp4" file that might be usable in Kdenlive. If this does not work you can re-encode it with: ffmpeg -i yoursource.m2t converted.mp4 This will re-encode the video and should work. To further debug the issue (probably an upstream problem in MLT), we would need access to the source file but I guess it's a huge file. So please first try my workarounds. -- You are receiving this mail because: You are watching all bug changes.
