How Long Are the Vidios on Youtube?

Start with longer form video, specifically on you two. And decide a niche, a category, a keyword, as you call it, that you want to dominate in and start making your content around that. Then after you've done that, take those longer videos and edit them down into two shorter videos that you can publish on the socials. There really is no right or wrong answer for how long a video should be, because it really is just good to depend on your audience.
