Another perspective, I don't feel like these informational videos need to be exciting. For this, I feel like 'just the facts' are a breath of fresh air.
Maybe exciting is the wrong word, but compelling is a better one.
For example, just the order of how you present information matters. Compare these two approaches:
1. "If you don't floss enough, then <BadThing> may happen. Here's tips on how to floss: A, B, C."
2. "Here's tips on how to to floss: A, B, C. Btw, this can help prevent <BadThing>."
The first is better. "Boring" information ceases to be boring and instead becomes compelling when you have a strong reason to want to know the information. Thus, it's important to hook people by giving them that motivational reason to watch/listen before you jump right into a video or article. Otherwise, you will likely only retain viewers who already arrive with their own personal motivations.
