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 *** When using the Ut Video lossless encoder, the resulting file is not Ut encoded. It is instead rendered as an H.264 file with medium quality settings. STEPS TO REPRODUCE 1. Import video to timeline 2. Render as Ut Video (utvideo+pcm_s24le) OBSERVED RESULT H.264 medium quality encoded output. EXPECTED RESULT Ut lossless encoded output. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Linux 6.0.11 (available in About System) KDE Plasma Version: 5.26.4 KDE Frameworks Version: 5.100.0 Qt Version: 5.15.7 ADDITIONAL INFORMATION Looking at the generated .mlt file, the consumer tag has: <consumer properties="lossless/Ut" ...> Looking at the settings in the render window when selecting Ut, I see properties=lossless/Ut Video channels=2 ... I suspect that the space in "lossless/Ut Video" is resulting in "Video" being cut off, which may be resulting in the codec not being located properly and the renderer falling back to a default.
Can confirm on Mac (release/22.12, built 2022-11-25) that the utvideo preset creates an h.264 video. Did not look into the parameters yet.
