I used to use OpenShot. I totally forgot how to use it after a few years hiatus and I could not find a way do what I remember I was doing, so I switched to plain ffmpeg. I use it to cut pieces of videos and extract the audio track. I use Audacity to denoise the audio, adjust the volume and silence some sequences. Then ffmpeg again to assemble everything into the final video. That never crashes and it's easier to document than working in a GUI.
