I have deactivated the track with all the titles in Kdenlive and did rendering again. On nearly all circumstances graphics and video section of the Nvidia showed up with loads of some few percents whereas the CPU runs with about 60% load continously. I could watch the load on CPU and GPU (Nvidia GTX 1650 4GB RAM) via Psensor. ![]() But when I loaded a project in Kdenlive, which contained three AV tracks and one title track for overlay, it endend up with nearly the same rendering time as on ffmepg software encoding with my i5-7400 CPU 3 GHz (4 threads). H265 did not work for me as the rendered file did only contain audio. Just another small handy tip I wanted to share for those making Linux gaming video content.F=mp4 vcodec=nvenc_hevc acodec=aac g=120 global_quality=23 ab=384k vq=23 r=60 preset=slow bf=2 It wasn't to me and likely isn't to others. The drawback, is that it will use some extra hard drive space, but it makes things much easier to do.Īgain, if you're a kdenlive or video editing pro, this is likely old news to you. Make sure "Proxy clips" is ticked and then it will begin to make a proxy of your video clips, which will allow you to have a very smooth editing experience. ![]() Simply go to the Project menu at the top, then Project Settings and you will see something like this: It essentially makes a low quality copy of the videos files you're using while editing, to make it easier on your computer. I had been looking around for other editors, but it turns out that the solution to this problem is already built into Kdenlive and has made me love it even more. For me today, it got to a point where editing a particular video became so slow it was impossible to work with. ![]() Seeking through the timeline and the timeline video preview will be extremely slow and stutter a lot, if your file is on the large side. Kdenlive is a pretty great video editor, but it does have a problem when it comes to large files. This tip is about working with large files, like longer or high quality gameplay videos. This is likely something many of you who edit videos frequently already know, but here's a small tip for those of you (like me) who aren't massively familiar with all the video editing options available.
