Changing video editing software a few days before the planned publication of the work from it is probably not the best idea. But #Kdenlive does not take it out and often crashes even when working with one footage for a couple of tens of seconds, so I took #DaVinciResolve and try to get used to it in an accelerated mode. At least it does not crash, which is already good. But for some reason he can not do in MP4, forcing me to convert all the sources, which now they do not fit on the drive.
