Visual Editor is an "visual" or "WYSIWYG-like" online rich-text editor, which allows you to edit wiki article in a more intuitive way - just like in Microsoft Word. If you have basic knowledge about wikitext, and you want to have more control in how you want to format text or do something more advanced(such embedding a video,etc.) you can choose to edit in wikitext editor.
