Product: kdenlive
Version: 18.08.3

SUMMARY
I make rendering of project with default preferences of "MPEG-2" profile from
"Generic" group. It going very very slow and all the time loads my CPU at 100%
(CPU = DualCore, 3 GHz on each, RAM = 4 GB). "estimated time" is constantly
growing while the progress has not reached 50% and only then start to decrease.
At the same time, the estimated time was determined completely incorrectly - if
believe him, everything had to end in 3 hours. In fact, the rendering after
progress at 50% took about 7 hours. Whole rendering - about 12 hours.
