Can this program trim .MP4 files?

Is this program capable of making trims to .MP4 files? We just want to trim off some of the beginning and end of the video. It was not created in ActivePresenter, so there are no source files or anything like that, only the finished .MP4.

Hi,

Yes, of course, Scott.
ActivePresenter provides you with basic to advanced video/audio editing tools.
Trimming a part of a video is just one of the various functions that ActivePresenter can help you.
Just insert your .mp4 file into the app then easily select the range you want to trim.
For more details, kindly take a look at this article: Basic Audio and Video Editing: Cut, Copy, Delete, and Crop -
Or, you can follow the quick steps in this video tutorial:

Hope it helps.
