WRITE A SCRIPT OR OUTLINE
Writing a script in advance will help you organize your thoughts so that you're prepared once you're on-camera. You don't have to follow the script verbatim. In fact, sometimes I write scripts and never even look at them while filming my on-camera talking scenes.
Writing your thoughts out is just another way to practice what you're going to say.
PRACTICE OUT LOUD
After you've figured out what you want to say -- practice some of it out loud. Sometimes there are sentences that look fine on paper, but are tough to get off your tongue when you're speaking out loud. Practice saying a main points will help you figure out which sentences sound too stiff or un-natural. This is basically the part where you take a proper-sounding script and throw some of your own voice into it.
Find the parts that make you think "I would never say it like that out loud" and switch it to a conversational tone -- something you feel comfortable saying.
TAKE IT ONE SENTENCE AT A TIME
I hate to break it to you, but you're going to mess up. It's a given. While jump-cuts are incredibly popular and totally normal on YouTube, they tend to be distracting if you have multiple of them mid-sentence. If you pause, fumble or forget what you're saying mid-sentence start over.
It makes editing seem more seamless when the cuts are between each sentence rather than the middle of a thought.
TALK TO YOUR EDITOR ON-CAMERA
Whether you're the editor or you've hired an editor, leave some on-camera notes! Sometimes when you're filming you have a certain vision for certain parts. Talking and leaving notes on-camera will ensure that the notes will never get lost and you or your editor will never forget what it is you want that piece of footage for.
Maybe you're talking on-camera and you realize that you've been talking too long about the wrong thing. Stop and say "Okay. I wan't all of that where I'm talking about "x" cut out. Let me start over..." or "over this next part, put some b-roll of x, y and z here" and resume or start over what you were saying.
If you're filming b-roll footage that doesn't require audio, feel free to talk during it -- or take the time at the beginning or end of that clip to talk your notes over. You could say something like "I want some of this footage that I'm taking right now to be part of a montage," or "do a timelapse or speed up this footage here."
If you're your own editor it may be weird to be talking to yourself at first, but trust me--it'll come in handy!
