The best way to make enticing videos, is by remaining consistent in what you film and the way in which you present it. By having a similar style of editing on each video, the material released almost becomes like a series and in return, the show's material becomes better.
How you deliver your video is paramount.
The video doesn’t have to be professionally shot but does have to somehow hold the user's attention. Whether this is via props or animated elements on top of the video, you need to keep the user stimulated.
The heading of the video is extremely important.
Make it as punchy and attention grabbing as possible. The topics that you talk about need to be interesting and current. It is also useful if they can be illustrated on screen with graphics which will offer an exciting, more visual way of presenting your ideas.
When talking in a video, you also need to be careful how much detail you go into. If the topic warrants a lot of explanation, then try and split the video up into 3 or 4 shorter videos rather than 1 long one. “Make sure you have finished speaking before your audience has finished listening.” Dorothy Sarnoff.
