SUMMARY Exporting a projet with multiple audio tracks to separated files was possible in Kdenlive 18.someting. There is still an option "Export audio multistem" ("Export audio multipise" en français) but it is just ignored and the rendered audio track is a mix of the project tracks. STEPS TO REPRODUCE 1. Make a project with one video and two audio tracks named audio1 and audio2 2. Render ac3 audio with "Export audio(automatic)" and "Export audio multistem" options on OBSERVED RESULT Only one file project.ac3 is generated as in not multistem audio export. EXPECTED RESULT project_audio1.ac3 and project_audio2.ac3 SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: (available in About System) KDE Plasma Version: 5.15.4 KDE Frameworks Version: 5.56.0 Qt Version: 5.12.2 ADDITIONAL INFORMATION
Just in case you were wondering, the latest appimage works the same.
Stem-Audio-Export doesn’t work in 19.04ff anymore. See issue: https://invent.kde.org/kde/kdenlive/issues/211 BTW: you can run an old versions of Kdenlive using the AppImage. Choose one from the Download page: https://files.kde.org/kdenlive/release/
