OpenShot does this very well. Clip and delete few frames here and there or whatever. Export video. Output file remains same bit rate within a few bps, same file size within a few bytes, and looks to me like same quality, and same sound quality and channels as specified. Takes 2x - 3x to output, though, but it’s worth it.
VidCutter will do the same, but it’s UI is bad. Mainly for lack of zoom control and frame selection. Also, it crashes a lot. Probably can’t handle big files. IDK. Use OpenShot IMHO.
ShotCut is a way, way better editor UI, but I don’t know why this task is so hard (impossible) for this program.
