I had made a 107 minute video with kdenlive - exporting slides from a Google Slides presentation, and syncing with audio. While rendering it, found this link,

melt /path/to/project.kdenlive -consumer avformat:output.mp4 vcodec=libx264 b=5000k acodec=aac ab=128k
went at 1.6x - 3600 frames in 72 sec
375% CPU with top. The entire render took approx 75 min.
Kdenlive was going at 0.6x - the 107 minute video showed 2:45, i.e. 165 minutes to complete.
250% CPU with top.
So, rendering with melt is more than twice as fast as rendering in kdenlive. This was with kdenlive-18.12.1b-x86_64.appimage and melt -version shows 6.0.0.
