SUMMARY *** NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols. See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports *** STEPS TO REPRODUCE 1. 2. 3. OBSERVED RESULT Kdenlive will try to Pre-render the stuff on the timeline but will fail after a few seconds. EXPECTED RESULT Pre-rendering failed. (See screenshot) SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: (available in About System) KDE Plasma Version: KDE Frameworks Version: Qt Version: ADDITIONAL INFORMATION
Created attachment 159233 [details] Screenshot of my timeline
Created attachment 160270 [details] A shot of the failed pre-render and a shot of the one (disabled text layer) with the successful pre-render So we finally pinpointed the cause. the title clip is causing the pre-render to fail. Further Explanation: If we disabled the title clip, the pre-rendering goes without any problems, but if we enable it and try to pre-render, It fails. So something is wrong with the way Kdenlive handles title clip and pre-rendering.

I can confirm this also for Linux 23.04.3 A simple single title clip in the timeline results in an error: Preview Rendering failed, check your parameters. If the Show details link is available it will show this error: libpng warning: iCCP: known incorrect sRGB profile
