Dear Phil,
If you use the Trim or Multitrim options the sections marked will be left, while the sections that are unmarked - will be deleted; so you might have misunderstood the feature. You can find the detailed information in
AVS Online Help.
it might be easy for you to use the Split option to split the video into several parts and delete the unwanted one, you can also use the Next Frame, Previous Frame on the preview window to make editing more precise - please see the screenshot attached.
Please let me know if I can be of any further assistance to you.
Kind regards
