There must be many users who are confused by how to crop YouTube videos. Indeed, not being able to get direct help from YouTube's official video editor makes everyone feel very disappointed. Often what we can do is find other ways, but the results are always irrelevant.

All these inconveniences make me eager to share the following pro-test effective methods with you.
