Created attachment 105510 [details] Rendering with all threads First of all, I know that is experimental function but for 8 threads in my PC it's a pity. When I use 1 thread, Kdenlive works fine but sometimes I have CPU bottleneck. It's not so bad but maybe, if I could use for preview 2=>8 threads at the same time, 1 thread was wouldn't so busy. It's not important but it's a pity. Rendering works fine with all 8 threads and rendering time is more than twice faster vs with 1 thread. How it looks: https://youtu.be/67z88hs49OU My PC: OS - KDE Neon 5.9.5 Kernel - 4.8.0-51 CPU - Intel Core i7 7700 RAM - 16GB 2400Mhz
Thanks for your report, this option has been removed altogether from Kdenlive since it is very buggy. We expect better support for multithreading in future versions of MLT.
