If the recent releases of Kdenlive, OpenShot, Pitivi, and others haven't satisfied your needs, perhaps you may want to try out the latest build of Avidemux.

For those in need of a basic cross-platform, open-source video editor, Avidemux 2.6.16 is now available. Avidemux 2.6.16 is coming just one month after the previous release and together provide a modestly-sized bundle of updates. Avidemux 2.6.16 updates its FFmpeg library, adds a resizer to VA-API, improvements to its Qt user-interface, fixed sub-titling on macOS, re-emabled NVENC video encoding support, and build system improvements.

November's Avidemux 2.6.15 release had improved hardware decoding support, added support for HEVC/VC1 with VA-API on Linux, fixed NVENC NVIDIA video encoding, experimental Dxva2 video decoder for Windows, and various other updates.
