Hi,

The environment
Kdenlive Version 18.08.3
MLT version 6.10.0
FFmpeg libraries
KDE Frameworks 5.52.0
Qt 5.11.2 (built against 5.11.2)
The xcb windowing system

Operating system: Arch Linux
GPU: GeForce GTX 1050 Ti

The issue
I am watching my GPU and CPU usage with #watch nvidia-smi and #htop . When I start rendering my movies, I can see, that the CPU usage shots up to 100% ... while the GPU remains around 2% ... despite I have installed the ffmpeg-full-nvenc package on my computer.
First thing I discovered: when I start the rendering process, I can see in nvidia-smi that a now process /etc/bin/melt is added.
Second, I saw that in Settings --> Configure Kdenlive --> Environment the fields for "FFmpeg", "FFplay" and "FFprobe" are empty.
(but even after adding /bin/ffmpeg in the FFmpeg field nothing changed).

--> How can I make usage of my GPU at least for rendering? I would be very happy for any hints, how to solve this ...

Although I have to admit, that my "GPU, Rendering and Kdenlive" know-how is almost zero, but I assume there is still a difference, which justifies both posts?

For a real rendering process, which finally results in an own "stand-alone-file" (e.g. mp4), it seems that there is the option to use directly ffmpeg. I assume, the trick here is to do the profile settings right.

However, the other posts is not about rendering the kdenlive-project into such a separate file. Here the issue is, that during working on the kdenlive-project you can play your movie "on-the-fly" ... maybe both is in the background the same ... I just don't know, but it looks like those are two different things (again, just the assumption from a not so experienced user ... hope you understand ...

Not that easy as MLT & FFMPEG is involved. See here: https://mail.kde.org/pipermail/kdenlive ... 10404.html
