How can teachers use video?

I discovered several ways how to use video as a teacher to make our lives easier.
The ideas below are represented in the following video "Innovative Education Think Tank - Using Video In The Classroom":

USING VIDEO FEEDBACK

• Personal connection;
• Good for online students;
• Easier to say and explain orally than in writing;
• Less time than typing. 

GUEST SPEAKERS

• Remote location;
• Support theory in the classroom;
• Interesting through a video;
• Easier to access busy people whom students will not see in real life;
• See things from different perspective;
• Make things real (alive) to students;
• Different way of presenting.

COMPACT INFORMATION-PACKED VIDEOS

• Answers to repeating questions; 
• Very fast on-demand piece of information; 
• Accessible; 
• Review for exams; 
• More time for interaction in the classroom; 
• More activity among students; 
• Clear delivery, chance to re-watch if necessary.  

SCREENCASTS

• Available lectures; 
• Better than just power-point presentation; 
• Less pressure with note-taking; 
• Hard first time, much easier later; 
• Visual learning. 

Teachers can also make videos more interactive and use them as a form of assessment with the help of such resources as EDpuzzle and TedEd.

Here are very quick and simple tutorials for these two.

First is ED Puzzle Tutorial.

Second is TED-Ed Website Tour.
