Problem: Audio effects Compressor/Eypander (avfilter.compand), Crossfeed, Crystalizer, Deesser, Haas Stereo Enhancer, Limiter, Pan, Simple Compressor/Expander (avfilter.acontrast), Stereo tools, Stereo widener, cause extreme distortion/clipping in timeline playback AND rendered output. Same clip sounds perfect in Clip Monitor. STEPS TO REPRODUCE New project (default settings) Import any WAV file, place on single audio track (no video, no other tracks/effects) Apply one of listed effects (e.g. Limiter, Stereo Tools) Timeline playback: heavily distorted/clipped Render to any format (e.g. MP4, WAV): distorted identically Clip Monitor playback: clean audio OBSERVED RESULT EXPECTED RESULT SOFTWARE/OS VERSIONS System: Manjaro XFCE (current), Kdenlive 25.12.0 (and previous version), MLT 7.34.1, only SDL audio backend available. ADDITIONAL INFORMATION IMPORTANT: Official Kdenlive AppImage (same version) with identical project/clip/effect: perfect playback and render. No config changes, clean user profile tested. Likely packaging issue in Manjaro's MLT/Kdenlive build affecting audio effect processing.
Manjaro packaging issue confirmed: - All functional MLT/FFmpeg versions show identical distortion - Downgrades break dependencies (missing libs) - AppImage works perfectly as control group → Manjaro maintainers: please check FFmpeg/MLT build flags post-8.12.2025
Strange, there was just a new update to Kdenlive 25.12.0-1.0, but there has been no improvement in the audio effects.
Noch ein Hinweis: Wenn man die updates bei Manjaro und Kdenlive Repos macht, dann startet Kdenlive nicht mehr, es sei denn, man löscht zuvor die kdenliverc.
One more note: If you update Manjaro and Kdenlive Repos, Kdenlive will no longer start unless you first delete kdenliverc.
