Playing back clips in the clip monitor has incredibly choppy sound. The latest release branch does not have this issue. Clips have been captured with Canon 5DmkIII, at 25fps all I-frames.
Please try with the latest Kdenlive Nightly AppImage version: https://binary-factory.kde.org/job/Kdenlive_Nightly_Appimage_Build/lastSuccessfulBuild/artifact/
