I just made a short video about our software.I was simply wondering why sometimes the rendering took so long. This really is like making a cake.There are ingredients to be used,pieces,cutting,stirring,then finally,the oven trip.This is the waiting period,where sometimes the cake can fall. Its a great way to learn videography.Check out Vic Licorish--Long Live Kdenlive! on youtube ; MrCyclopsking.Check out all of my videos. The latter ones are all made with kdenlive.
