Here's how I have to do it....
Add file (video)
Click on imported video once...it get loaded to clip preview window.
Okay, you will be selecting clips of the video that you want to add to final movie...
Click on timeline part of clip preview window at its beginning of the portion of video you want to keep.
Then click red set in point button.
Then go back to clip preview windows timeline and click at end of video segment your keeping.
Click blue set out point button.
Then click green "add clip to sequence"
For more parts of the same imported video....
left click on a part of the Videopad program that will leave the clip preview window blank...it will say "no clip selected"
ignore sequence preview window
when clicking be sure not to hightlight bottom sequence video track, this will cause it not to clear clip preview window
then start again...
click on imported video once...
select beginning of next clip...etc.etc.
green button will change to say add clip to beginning or end of final sequence....
Once your clips are all in bottom sequence you can highlight each clip and move them around to order them.
Sometimes it placed clip where I couldn't see them in bottom sequence window until I scrolled it.
