Created attachment 183039 [details] High RAM usage + low RAM alert + plasmashell crashed, all in the same picture SUMMARY Kdenlive took 5.6 GB of memory to encode mild 1440p30 video, which is crazy for a simple cut and simple covering stuff with squares), which triggered OOM, crashed plasmashell and made my system run like a crawl. STEPS TO REPRODUCE 1. Put your project in 1440p30 and put something in it (a video in my case) 2. Put many color clips (at least 7) and use transform to make them cover subjects 3. Export with any codec with slow CPU encoding- could be x264 in veryslow mode OBSERVED RESULT Kdenlive uses an insane 5.6 GB of memory for cutting a video and covering stuff with black squares EXPECTED RESULT Kdenlive should use a VERY lower amount of RAM on encode time- at least low enough to make the system usable SOFTWARE/OS VERSIONS Windows: macOS: (available in the Info Center app, or by running `kinfo` in a terminal window) Linux/KDE Plasma: Arch Linux KDE Plasma Version: 6.4.2 KDE Frameworks Version: 6.15.0 Qt Version: 6.9.0 ADDITIONAL INFORMATION
