Desktop application to cut videos

Wanted to build a Desktop app (mac first) that will do one simple function. Cut and resize videos easily. Functionality should be this - Add a video - Select (can be as simple as just adding them one by one) different time stamps/clip stamps - The key here will be that I can add multiple timestamps in one go with names - The app will output all the clips which can be renamed if required in the same UI. - The clips can be resized in this step - Hit export and it exports all the clips in the sizes/dimensions required. This specific project is mostly as an MVP right now so it has to be functional. Ideally need someone with FFMPEG understanding and deep knowledge on how to implement this effectively.
