Summary0001608: Nice level for rendering (feature request for the rendering window and rendering subprocess)
DescriptionRendering generally needs lots of CPU ressources and takes a long time - at least for big projects and/or difficult codecs. To keep the computer responsive and usable for other tasks, it is a good idea to run the rendering process with a nice level, but this can't be defined in the rendering window (or inside kdenlive at all).
Workaround: Let the rendering windows create a script for you, exit kdenlive and start the script with an appropriate nice level.
The problem might be irrelevant on multicore systems (don't know, have a single core).
Steps To ReproduceJust render and watch CPU usage.

I would like to see the ability to specify how many processors the renderer can access, also. I have manually re-niced mlt to as high as 19 during renders, and still it made the system lag noticeably normal use. I have a dual core 2.5 gHz Intel processor and 2 gigabytes of RAM.
