--- Comment #1 from Jean-Baptiste Mardelle <j...@kdenlive.org> --- It is a known issue that generating the audio waveform is currently slow in Kdenlive. One idea is to use a performant library like: https://github.com/bbc/audiowaveform to generate the waveforms (it is approximately 3 times faster than our code), but it will take some time until this is implemented. In the meantime, you can disable audio thumbnails for a project in: Project > Project Settings > Thumbnails Uncheck "Audio". To disable thumbnails for new projects: from the Kdenlive Settings > Timeline Uncheck the "Enable for audio" option in Thumbnail. -- You are receiving this mail because: You are watching all bug changes.
