Read your script out loud as you write. This helps you avoid complex sentence structure.
Reduce your script to talking points. This helps you draw on your natural conversational tone.
Rehearse, but don’t overdue. Over-rehearsing can suppress spontaneity.
Warm up your voice by reading something out loud, fast, while over-enunciating.
Present
Check your posture—with your head, spine, hips (and, if standing, feet) comfortably aligned. This can relax you and help your lungs and diaphragm work efficiently.
Be enthusiastic, but most of all, be authentic.
Smile on the inside.
Think about helping others while you present. This focuses your attention away from self-consciousness and engages you with the learner.
Use a conversational tone. You know the person on the other side of the lens.
Look into the camera lens occasionally, but do not stare it down. Allow yourself to naturally look elsewhere as you rephrase and then look back to the lens for emphasis.
Allow yourself to make gestures, but avoid jabbing movements toward the camera lens, shuffling feet, or constantly shifting.
Use talking points that provide the framework to keep you organized while allowing you to speak with some spontaneity.
Revise
Watch your recordings and take notes on revisions you would like to make when updating your recordings.
Note the difference between picking up the pace versus talking faster. If you are losing energy, consider how to say something more concisely or find a way to illustrate a point.
Watch how you emphasize words and phrases. Are you emphasizing the key words in a sentence?
Get feedback from reviewers. Ask a few people to review and share observations.
Determine a schedule for replacing recordings. As the content expert, you know when a recording may need revision or replacement.
