FYI, if one has or creates their own You Tube channel, one can use the following editing feature via the Playlist application:
Advanced playlist features and strategies
Feature: Start and End Time
Find it: In Edit Playlist
What it does: Sets the “in” and “out” points for any video in a playlist. Allows you to create a seamless curated experience, highlighting and connecting select moments in videos. This feature is especially useful if your videos include repetitive opening titles and credits; you can use it to omit these portions of your videos.

I believe that all of the videos I listed are on You Tube with the exception of the video on vicarious trauma.
