The 5 Essentials for Online Video Tutorials

I have been creating tutorial videos for Rezgo recently and have viewed several others on the internet, here are some essentials for making effective and interesting tutorial videos:

1. Smile when you talk - You can really tell the difference in your voice if you are smiling or if you have a straight face. No one wants to listen to 10 minutes of droning.
2. Zoom in - Don't have a full screen perspective for your entire video, show some movement and move the video frame to where the action is.
3. Highlight your pointer - It is difficult to follow a small pointer in a small video screen, add some highlight to help the viewer follow your mouse.
4. Add music - A little background music helps to fill in those pauses in the voice, it shouldn't be too distracting, but should still be upbeat.
5. Keep it short - Break up you tutorials into small digestible chunks. Don't assume that people have an hour to setup a system or account, break it up. There is a sense of accomplishment in completing small steps along the way, your viewers will appreciate it.

Here is what I have done thus far, you can see the progression of my own work as the first tutorials don't use all of my suggestions, but they get better with experience. What do you think?
