If I simply start a new project, adding the whole Sintel short film to the project bin, cutting the first minute and render it, nvenc simply does not work and the render time is tripled, despite having changed nothing else, including the nvenc render profile. After launching the ppa/installed version of kdenlive and opening this save file, rendering with nvenc works flawlessly. I have only been able to get rendering with nvenc to work properly when I use and open this specific kdenlive save file which I made of the first minute of the Sintel short film with the Appimage Version of Kdenlive. Using the latest version of kdenlive from the kdenlive-master ppa combined with the newly compiled versions of ffmpeg and mlt works perfectly, but only under very s pecific circumstances. Now here is the problem that I do not understand: Nvenc Profile: (compatible with recent mlt versions who are nvenc enabled by deafult)į=mp4 vcodec=nvenc_h264 global_quality=21 vq=21 preset=slow bf=2 ab=384k Rendering the first minute of the 1080p Sintel version, with 4 threads specified and my nvenc profile, finishes in 10 seconds.
I have successfully compiled mlt and ffmpeg with nvenc support using the official nvenc headers stripped from the Nvidia SDK.
