Hello. I use Kdenlive for my video editing needs and I notice that on my Intel Core i7-4790K CPU, when rendering, Kdenlive does not fully utilize the CPU. The CPU usage hovers at around 20% and that's as high as it goes. I feel that if Kdenlive were optimized for multicore/multithreaded CPUs, that it would be more efficient and would render videos much faster with faster CPUs.
