I have reproduced this with the latest release (kdenlive-20.12.0-x86_64.appimage) and what was the latest daily yesterday (kdenlive-21.03.70-984f452-x86_64.appimage) Some clips have really glitchy audio. Additional noises that shouldn't be there, chunks of sound that might be backwards. I can hear these problems both in the plaback in kdenlive, and the rendered output. I tried deleting the clip entirely from the project, saving, exiting, reloading, then re-adding the clip, no change. I worked around it by extracting the audio with this command, and adding it separately, which worked fine: ffmpeg -i *4519* -vn -acodec copy output-audio.aac I'm attaching samples this is happening for. An original that sounds fine through mpv, and the same thing just added to a kdenlive project and exported. An awful lot of the audio processed by kdenlive seem not quite right, this is just an example of where it is more noticable. The source is an LG G6, using the stock LG camera app. mp4, Selected audio codec: [ffaac] afm: ffmpeg (FFmpeg AAC (MPEG-2/MPEG-4 Audio))
