What it does
Flowblade is a GPL3 nonlinear video editor with multitrack editing, compositing and a G'MIC filtering tool.
Use its timeline tools to assemble a cut, then combine images and audio through the documented compositing and filtering controls. The project explains that available media support follows the Linux system and FFmpeg backend, so confirm your actual source formats in your installed environment.
Strengths
