In the Timeline, there are these two red markers.
Use them to mark the beginning (eg. frame no.1) and end of a video clip (eg. frame no. 100).
Export the first video clip.
Then, mark the timeline again (eg. frame no. 200 to frame no. 300).
Export as the 2nd video clip.
The unwanted part (eg. frame 101 to 199) is not captured as a video clip.
