Hello I just needed to download and locate ffmpeg libraries.

sorry i can't understand... the FFMPEG is provided already on Kdenlive for Windows and there are not issue about CRASHES on preview (no more for what i know)

are you referring to a specific issue? https://invent.kde.org/kde/kdenlive/issues

have you tried latest Nightly of Kdenlive for Windows? https://binary-factory.kde.org/job/Kden ... 64-gcc.exe

Hello thanks for your reply. I'm not sure if ffmpeg library works properly there. I've had this problem also using Subtitle Edit. Sorry for my English.
