I think if the use case is as simple as it sounds, a video editor
is not really needed.

If you re-encode the video anyway, there should be multiple easy
ways to achieve your goal with filters.

If you don't want to re-encode the complete video, than it will
require quite a stunt, which potentially can be achieved with
ffmpeg, but ffmpeg won't be helping you to achieve it. The risks
of errors might be to high to try that.

Maybe there are other tools or video editors that support this,
but I just don't know.
