--- Comment #16 from Scott <shagooser...@gmail.com> --- I did some more tests on large files and discovered that there is indeed some problem with Kubuntu that is directly affected by what size file it is working on. For the tests I used MKVtoolnix GUI Ver 50 once on Kubuntu 20.04 against the same files and MKVtoolnix on Windows 10 using the same hardware, including disks. The test involved re-muxing a video file from an m2ts container to an mkv container, therefore the data of the movie was not changed. File size is output size. This is repeatable. File Time Size Windows Kubuntu 1GB 11 secs 7 secs (45 min TV show) 6.2GBs 2 mins 23 secs 2 mins 30 secs (typical DVD) 18.8GBs 6 mins 43 secs 38 mins 45 secs (HD Blu Ray) 43.4GBs 14 mins 172 mins (UHD Blu Ray) As would be expected the time increase for Windows is fairly linear being dependent on file size whereas Kubuntu needs fixing. -- You are receiving this mail because: You are watching all bug changes.
