Techsmith Camtasia Studio (https://www.techsmith.com/camtasia.html) worth to look into. Some of the feature:

• Unlimited tracks
• Split, delete, and stitch
• Noise removal and leveling
• Captioning/Subtitle
• Callouts - Arrows, cursor effects, keystrokes, sketch motion illustrations, text boxes, highlights, blur, and more--help you get your point across.
• Green Screen - Camtasia’s chroma key effect removes the background color of any video. Layer it on top of your recording to put yourself right in your video.
• Export your video projects in a variety of file formats (MP4, WMV, MOV, AVI, etc.)
• Send your recordings straight to accounts you already use like YouTube, Vimeo, Google Drive, and more.

I used it most of the time because of the feature, simplicity, drag & drop, not too technical & suit for most task. You can check lot of tutorial in the Youtube. Even after install it, it will show tutorial on how to use it.
