SUMMARY STEPS TO REPRODUCE 1. Render a video and set the target file to one on a NFS drive 2. Rendering fails 3. But saving the project to the same location does succeed ! OBSERVED RESULT Rendering fails with message "Cannot write to mnt/Public/Pictures/20190101_Vuurwerk/vuurwerk.mp4, check permissions." EXPECTED RESULT That I can get the resulting video in the chosen location. On the command-line I can move it to that NFS location, so it is not a permission issue. SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: (available in About System) KDE Plasma Version: KDE Frameworks Version: Qt Version: ADDITIONAL INFORMATION Maybe related to this https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=946964 ?
It could be a Debian issue. Clips and rendering to a USB connected drive could be a problem as well. Unfortunately 18.12 and older Kdenlive versions are not maintained anymore. You can try with 19.04 AppImage. Kdenlive 19.08 and 19.12 need Debian 19.04 or newer.
Installed KDENLIVE 19.12.1 (flatpak) and there it all works: I can save to the NFS drive without problems. Issue solved.
Thank you for the feedback. Glad to hear it works.
